An Improved LEACH Protocol in Wireless Sensor Networks
Wireless sensor network routing protocol is to prolong the survival time of wireless sensor networks by using the sensor nodes energy efficiently.Traditional LEACH protocol is random in the election of the cluster head,if a less energy node is first elected as a cluster head node,then the node might die soon,it will greatly reducing the lifetime of the network.In order to collect data more efficiently and prolong the network life cycle,we need better clustering protocol.Aim at the traditional LEACH protocol have some weakness,this paper improve the protocol based on traditional LEACH protocol,two influence factors which the residual energy and the number of elected cluster head of the nodes had been introduced to make the clustering more ideal.Simulation results show that compared to the traditional Leach algorithm,the improved LEACH protocol can prolong the network life cycle more effective and reduce the energy consumption of the whole network.
