Improved Route Algorithm of Wireless Sensor Networks

Wireless sensor network(WSN) is an energy limited special network,traditional LEACH routing algorithms can not consider the surplus energy of cluster head and energy balance,resulting in very short network survival time.In order to prolong the network survival time,this paper put forward an improved LEACH routing algorithm.In the cluster head choice stage,the cluster was chosen by the surplus energy nodes,avoid the nodes with low residual energy becoming cluster heads.Then,in data transmission stage,the hybrid transmission mode with single-hop and multi-hop was used to balance the whole network energy.The simulation results show that,compared with the traditional LEACH routing algorithm,the energy consumption of all nodes in the network is more balanced improved algorithm and the life time of the entire network is prolonged.
