A Novel Solution for Energy Hole of Wireless Sensor Network
Wireless Sensor Network (WSN) is multiple hops network.Nodes near sink are required to transmit a large amount of data and expend energy rapidly.These nodes die early and outer nodes can not send data to sink.Therefore the network dies early with much unused energy.This phenomenon is called energy hole.Aiming at energy hole problem of WSN,a novel solution is proposed in this paper.According to the distance one node to sink and number of nodes in different distance to sink,energy is distributed to nodes nonuniformly.Correspondingly,we proposed a distributed conditional greedy routing algorithm for the nonuniform energy distribution strategy.Finally,simulation results have been given to validate our strategy.Results show that our strategy extends the network lifetime and reduces the waste of energy.Aiming at simulation results,we propose energy-cutting measure to compensate the weakness of our strategy,and simulation results prove that the measure can extend the network lifetime better.
