Novel Energy Efficient Election Based Routing Algorithm for Wireless Sensor Network (Published)

Sensor nodes close to the sinks will deplete their limited energy more rapidly than other sensors, since they will have more data to forward during multihop transmission. This will cause network partition, isolated nodes and much shortened network lifetime. Thus, how to balance energy consumption for sensor nodes is an important research issue. In recent years, exploiting sink mobility technology in WSNs has attracted much research attention because it can not only improve energy efficiency, but prolong network lifetime. In this paper, a modified  Election based Protocol, which employs the  decision  of  selecting  cluster  heads  by  the  sink  is  based  on  the  associated additional energy and residual energy at each node. Besides, the cluster head selects the shortest path to reach the sink between the direct approach and the indirect approach  with  the  use  of  the congested link.  Simulation results demonstrate that our algorithm has better performance than traditional routing algorithms, such as LEACH.
