A Mobile Sink Routing Algorithm Based on Grouping SLE Measurement
Han Yu Lao, Fang Ding Yi · 2018
In this paper, a novel mobile sink dynamic routing algorithm is presented to solve the problems including huge energy consumption and imbalance of energy consumption between nodes in wireless sensor networks (WSN). The algorithm selects cluster head of each group with the help of SLE measure. In order to deal with the NP complete problem of the mobile trajectory planning of the sink, the paper proposes an approximate solution. Simulation experiment shows that the algorithm can balance energy consumption between nodes and improve the network lifetime in WSN.
