Abstract Wireless Sensor Networks (WSNs) are usually formed with many tiny sensors
which are randomly deployed within sensing field for target monitoring. These sensors
can transmit their monitored data to the sink in a multi-hop communication manner.
However, the ‘hot spots’ problem will be caused since nodes near sink will consume
more energy during forwarding. Recently, mobile sink based technology provides an
alternative solution for the long-distance communication and sensor nodes only need to
use single hop communication to the mobile sink during data transmission. Even though
it is difficult to consider many network metrics such as sensor position, residual energy… More >
