Energy efficient multi-sink relocation in wireless sensor networks
Tiantian Yuan · Computer Engineering and Applications Journal · 2013
Deploying only one static sink in Wireless Sensor Networks has many drawbacks,such as imbalanced network energy consumption,short network lifetime,and large packet loss rate.This paper proposes a new and feasible multi-sink relocation algorithm EEMSR to resolve the above shortcomings.The EEMSR algorithm moves the multiple sinks to the optimal position respectively in the whole network lifetime by means of approximation gradually and cooperation.The simulation result shows that the application of the EEMSR algorithm can prolong the network lifetime enormously and enhance the packet delivery ratio greatly.
