Improvement on LEACH Protocol of Wireless Sensor Network
Wireless sensor networks comprise of minor battery driven devices with restricted energy resources.Once installed,the minor sensor nodes are usually unapproachable to the operator,and thus auxiliary of the energy source is not practicable.Hence,energy proficiency is a vital design issue that needs to be boosted in order to increase the lifetime of the network.LEACH is a popular hierarchical routing protocol which efficiently maintains the energy storage of nodes in Wireless Sensor Network(WSN).The nodes using LEACH are divided into clusters.The advantage of LEACH is that each node has the equal probability to be a cluster head,which makes the energy dissipation of each node be relatively balanced.This paper studies LEACH protocol,and focuses on how to decide the next hop nodes more reasonable when the data are transmitted at the steady state.Simulation has been done in NS2 and the results show that the algorithm after improved is more energy-efficient than LEACH protocol.
