Application of mobile sink in wireless sensor networks

Motivation: In the last couple of decades, Wireless Sensor Networks (WSNs) have been used in a variety of applications which include military, agriculture, environment monitoring, home automation, smart transportation etc [1]. The sensor nodes in WSN are battery driven devices which collect data from the environment and forward this data to the sink for further processing leading to the energy consumption of their batteries. The batteries may be difficult to replace or recharge in certain environments. These problems have lead the path to the design of new protocols for energy-efficiency of the sensor nodes. In a typical environment, the sensor nodes exhibit many-to-one communication with the sink, resulting in faster energy depletion of the sensor nodes near the vicinity of the sink which is famously known as the energy-hole problem or the Hot-Spot problem [1]. Sink mobility can help in the balancing of the energy dissipation of the sensor nodes [1].
