Intelligent water droplet-based sink path planning algorithm in WSNs
In order to avoid the hotspot problem in a Wireless Sensor Network(WSN), a portable sink is utilized to gather information from the sensor nodes. A portable sink might be permitted to visit just a restricted number of sensor nodes, alluded as Rendezvous Points(RPs). The rest of the sensor nodes send their information to the closest RP so as to avoid the postponement due to visiting all the sensor nodes. Therefore, it is very important to determine an optimal set of RP in order to enhance the information gathering procedure. An Intelligent Water Droplet-based Sink Path Planning(IWD-SPP) algorithm is proposed. This algorithm aims at boosting up the lifetime of the network and minimizing the network energy consumption in forwarding the data packets. A productive mechanism has been devised based on the behavior of IWDs so as to find an ideal arrangement of RPs and the mobile sink's routing path. Simulation results show that the proposed IWD-SPP algorithm has better performance in energy consumption and network life.
