AbstractDue to a tremendous increase in mobile traffic, mobile operators have started to restructure their networks to offload their traffic. New research directions will lead to fundamental changes in the design of future Fifth-generation (5G) cellular networks. For the formal reason, the study solves the physical network of the mobile base station for the prediction of the best characteristics to develop an enhanced network with the help of graph theory. Any number that can be uniquely calculated by a graph is known as a graph invariant. During the last two decades, innumerable numerical graph invariants have been portrayed and used for correlation analysis. In any case, no efficient assessment has been embraced to choose, how much these invariants are connected with a network graph. This paper will talk about two unique variations of the hexagonal graph with great capability of forecasting in the field of optimized mobile base station topology in setting with physical networks. Since K-banhatti sombor invariants (KBSO) and Contrharmonic-quadratic invariants (CQIs) are newly introduced and have various expectation characteristics for various variations of hexagonal graphs or networks. As the hexagonal networks are used in mobile base stations in layered, forms called honeycomb. The review settled the topology of a hexagon of two distinct sorts with two invariants KBSO and CQIs and their reduced forms. The deduced outcomes can be utilized for the modeling of mobile cellular networks, multiprocessors interconnections, microchips, chemical compound synthesis and memory interconnection networks. The results find sharp upper bounds and lower bounds of the honeycomb network to utilize the Mobile base station network (MBSN) for the high load of traffic and minimal traffic also.
Currently, there has been an enormous expansion in rush hour traffic demand for communication services in cellular mobile networks. The frequency spectrum dispensed to the frameworks is restricted; thus, how to utilize frequency diverts most efficiently whether the frameworks depend on the Frequency division multiple access (FDMA) or the Time division multiple access (TDMA) . FDMA is the correspondence procedure utilized in communicating, land-versatile two-way radio, and so forth. It starts with a band of frequencies, which is distributed by the Federal communications commission (FCC). This band of frequency is additionally partitioned into a few thin groups of frequencies, where every frequency, otherwise called a channel, is utilized for full-duplex correspondence. The correspondence connection is kept up within the two headings, either in the frequency space or in the time area. This is represented by two fundamental modes of tasks known as the Frequency division duplex (FDD) and Time division duplex (TDD). These subjects, alongside FDMA range the executives and its credits, are introduced in this section . In new mobile radio frameworks, TDMA is utilized. Every versatile hub doles out frequencies for the utilization of the period on a repeating premise. Generally, a telecaster doesn’t have full admittance to the game’s data transmission for a specific timeframe. The frequency of the framework, then again, is partitioned into sub-groups, each involving TDMA for shared confirmation . The network structure used in a cellular network system is a hexagonal structure with two variants . The study technique is used to evaluate and optimize the physical layout of the mobile base station to fulfill the optimal traffic demand in rush hours. It can be done by solving the topology of cellular networks by modern invariants and predicting the physical characteristics of the honeycomb network used in the mobile base station network.
A mobile telephone base station is a transmission and gathering station in a decent area, comprising of at least one get/send receiving wire, microwave dish and electronic hardware used to deal with cell traffic. It fills in as an extension between all mobile clients on a phone and interfaces mobile calls to the mobile exchanging focus. It is fundamentally the main issue that all clients interface within a center and talked style network .
In material sciences, honeycomb networks play a fundamental part in various fields, particularly in wireless base stations, image processing and graphics. Honeycomb networks are formed by the iterative utilization of hexagonal tiles in a particular plan. We mean the n-layered honeycomb network with hexagons among focal and boundary hexagons by HCn. HCn are built by adding a layer of hexagon around HCn−1. Its evaluation is also useful in other fields of computer science like microprocessors, memory interconnection and processor interconnection. As another arising science is developed with the help of computer sciences, mathematics, and chemistry called cheminformatics, whose significant segments incorporate Quantitative structure-activity relationship (QSAR) and Quantitative structure-property relationships (QSPR) and the segments can add to the examination of the physicochemical characteristics of synthetic mixtures. QSAR is a modeling tool used to solve the topology of networks or structure of compounds and model the efficient and best performer networks or structures. QSPR is also a modeling tool that correlates the properties of network structures with the help of mathematical equations or expressions. It also provides the quantitative relationship between properties of networks or chemical structures. Angles of topology in the form of numeric values can be portrayed with the help of a graph because of invariance. It is done due to the automorphism property of the graph. A k-banhatti sombor index is a topological index which is a number associated with a network graph that captures the symmetry of the network structure and provides a scientific language for predicting the characteristics of the network. In the fields of computer sciences and chemistry, there are a lot of applications of graph theory .
On the other hand, V. R. Kulli in 2022, define another vertex degree-based invariant graph named Quadratic-contraharmonic indices (QCI) are used to get the sharp lower and upper limits of the related networks and the characteristics of the network showing up at the boundaries. There are two varieties of quadratic-contraharmonic indices, the first is a QCI and the second one is a CQI . A QCI is a topological invariant which is a number related to a network graph that gets the evenness of the network design and gives a coherent language to expecting the characteristics of the network.
The research work concentrates on the topological properties and solutions of mobile base station networks. The topological properties include lower bounds, upper bounds and prediction qualities of deduced mathematical results to resolve the issues related to connectivity, scalability, routing, node density, mobility among the nodes, link formation between the nodes modeling the network and simulation. Though mobile base station networks are modeled through these solved results. So, engineers and manufacturers foresee concerning networks before manufactured or developing them. After that Topological invariants (TIs) allow us to accumulate information about algebraic structures and mathematically predict hidden properties of various networks like hexagons and honeycomb etc.
This paper first introduces the problem statement with Honeycomb and regular hexagonal networks and KBSO and QCIs, secondly review the literature, thirdly discusses objectives, significance, research gap, and method in the research methodology section, in the fourth section analyze data and in the last section write results and conclude the research. The study has implications in the fields of computer science, physics, chemistry, mathematics, and bioinformatics for modeling purposes of networks, cellular networks, and chemical compounds. KBSO topological invariants and QCIs allow us to accumulate information about algebraic structures and mathematically predict hidden properties of various structures such as Honeycomb and regular hexagonal networks used in mobile base station networks.
In a cellular mobile communication framework, to treat the traffic demand at the necessary grade of administration, some number of frequency channels ought to be allocated to every cell of the framework under the electromagnetic limitations, for example, co-channel imperative, contiguous channel requirement and co-site imperative. The quantity of frequency channels apportioned to a cellular framework is limited on account of the restricted frequency spectrum . In any case, lately, interest in frequency channels has been expanded definitely. Consequently, how to appoint the expected number of frequency channels to every cell under the above requirements turns into a significant issue. This issue is called FAP. It has been broadly utilized as a choice measure of FAP to limit the most extreme range of the frequency channels utilized in a cellular framework . This paper study enhances the efficiency of mobile cellular networks by evaluating the cellular base station networks’ topology mathematically by newly prepared topological indices. So issues are started to resolve from the gross root level . This study solved and optimized the MBSNs in context with the topology of the network.
The calculation of the irregularity indices of honeycomb networks, hexagonal networks, oxide networks, and silicate networks is done. The results are very helpful in understanding the behavior of different computer networks and chemical networks. After understanding these formulas different researchers can construct their own best networks in chemistry and computer also . Further, the study elaborates that graph theory is a field through which they calculate topological indices for finding the properties of different chemicals without performing any types of experiments on them. It may be understanding only mathematical formulas or equations which are deduced for them. It also calculates topological indices form-polynomial block shift networks which are a part of different chemical compounds with the help of the division of edge .
The readings explain that another arising science is cheminformatics which is a combination of chemistry, mathematics, and computer science. It is the main concern and constituent part is QSAR and QSPR which mainly explore physicochemical properties of chemicals and their structures. This paper tended to the OTIS traded networks and bi-swapped networks and investigated their topological indices. They decided the overall randi ć, general aggregate availability, first and second zagreb, first and second multiple zagreb, hyper zagreb molecule bond, and mathematical indices for both the group of networks by considering the premise network as way Pn and k-customary graph Rk. They likewise gave express formulae for ABC4 and GA5 indices of these networks with the premise Rk network .
In the view of the study, the headway of large-scale integrated circuit innovation has empathy for the development of complex interconnected networks. Graph theory gives a key apparatus to designing and evaluating such networks. Connected networks and graph theory give a detailed comprehension of these connected themes. Chemical graph theory is a part of numerical science wherein they apply devices of graph theory to demonstrate the chemical wonder numerically. In-network vertex addresses network hub like PC, switch, switch some other gadget and an edge addresses a network path through which transmission completed. These topological indices or invariants are also numeric values related to computer networks, their interconnections, their properties, etc. It calculates the different topological indices of eccentricity-based for a binary tree up to k-level. The results of a paper can be used for computer networks and chemical networks in topological characterization .
Chemical graph theory manages the essential properties of a molecular graph. In graph theory, we relate molecular descriptors to the properties of molecular structures. Here, we calculate some Banhatti molecular descriptors for water-dissolvable dendritic uni-molecular polyether micelle. Our outcomes end up being extremely important to comprehend the way of behaving of water-dissolvable dendritic unimolecular polyether micelle as a drug-delivery agent .
Multiprocessor interconnection networks are habitually expected to join numerous indistinguishable processor-memory matches that are rehashed everyone is alluded to as a handling hub . Message passing instead of divided memory is much of the time utilized for synchronization of correspondence among the handling hubs for the execution of the program. Multiprocessor interconnection networks are most drawn in networks because of the accessibility of strong and cheap microchips and memory chips. By rehashing normal polygons, intermittent plane decorations can be handily constructed . For direct interconnection organizations, this plan is vital as it offers high worldwide execution. A few equal organizations that start from well-known networks are hexagonal and honeycomb .
With the assistance of the topological index (TI), we can figure out various properties of molecular structures. TI empowers us to connect a number with a molecular construction. Various mixtures can be changed into various shapes like trees, cycles, and so on. This paper is about the reverse Zagreb indices, hyper turn around Zagreb invariants, and their polynomials for metal-natural structures .
In the field of chemical graph theory, topological indices are vital. The topological index is a mathematical amount reliant upon various invariants or molecular graph qualities. In the current article, the topological indices of para desert plants chain graph are determined, for example, iota bond availability, mathematical number juggling, first k-banhatti, second k-banhatti, first k-hyper banhatti, second k-hyper banhatti, adjusted first k-banhatti, altered second k-banhatti and consonant k-banhatti utilizing their M-polynomials by the equations given in. Graphical examination of the discoveries is additionally shown the capacity to recuperate the topological indices .
To increase the effectiveness of observing and conservation endeavors, it is of key importance to foster sound quantitative techniques that can indicate which key areas and site components play a noticeable and critical job in the working of territory mosaics. In this article, a new emerging study will compute different indices of bridge networks. The results will play a vital role in determining the properties of these networks and their uses in the computer industry, electronics, chemistry, pharmacy, etc. It will also perform index analysis on certain networks which may be beneficial for people who are working in the field of computer science, mathematics and chemistry also. In the end, formulate a mathematical formula to construct a computer network or processor design or chemical compound, check the properties of concerning before and also check the feasibility of anyone which discuss earlier .
Chemical graph theory is a subfield of numerical chemistry that is exceptionally valuable in the advancement of the computational examination of chemical mixtures. A chemical graph is the result of the molecular design by applying some graph The exhibit of chemical mixtures with the M-polynomials is a creating thought and the M-polynomial of various molecular structures upholds us to ascertain numerous topological indices. In this paper we ascertain M-polynomial and topological indices for the starphene graph, then, at that point, we recuperate various topological indices utilizing the M-polynomials .
The momentum disclosure of various kinds of nanostructures has propelled scientists to concentrate on the uses of these structures in various fields. In this review, the study dissected the boron three-sided nanotube through topological indices. M-polynomial of a boron three-sided nanotube can recuperate the topological indices which are reliant upon the level of the vertex. We have introduced the outcomes in a graphical structure .
These topological indices can contribute to getting the natural, chemical and actual qualities of a molecule. Along these lines, the topological index plays a vital part in addressing the chemical design of a particle in a genuine number and is utilized to communicate the atom which is tried. These outcomes are useful in understanding and determining the physicochemical properties of these chemical structures .
Another study told that topological indices and network polynomials are invariants of molecular graphs. Expected properties of structures of molecules can be studied with the help of invariants. In benzene networks, honeycomb networks are significantly used. In the current article, new topological portrayals of honeycomb networks are given as degree-based descriptors. They, for the first time, used some consistency indices and a few co-indices identified with this network without a line graph and complement also. These indices of honeycomb networks are very much effective to understand the physicochemical properties of chemicals. These realities might be valuable for individuals working in software engineering and science who experience honeycomb networks. An ideal level of a specific index can be acquired by putting a limitation on n .
Another study conveyed that since computers are a tool used in the world as a source of information, they increase in numbers numerously. To such an extent, today, it is hard to track down any space, logical or other, which is not dependent on their application. Indeed, even general sets of laws have been affected by novel processing and data strategies. A considerable lot of these QSAR procedures depend on the utilization of structural boundaries, which are mathematical arrangements that classify helpful structural data and empathy relationships among structure and natural properties .
KBSO index and its reduced version have a good potential for prediction in the field of computer science, mathematics, chemistry, pharmacy, informatics, and biology in context with physical and chemical structures and networks. On the other hand, the CQI and its reverse form are also having the same prediction quality as mentioned earlier.
