Improved LEACH Cluster Head Multi-hops Algorithm in Wireless Sensor Networks

摘要：

As WSN is a resource-constrained network, especially the limited energy, so it must maintain smaller router information and reduce the energy consumption as much as possible. This paper briefly introduces the wireless sensor network, and analysis the problems existed in LEACH routing protocol. Put forward the improved algorithm based on LEACH cluster head multi-hops algorithm, and under considering the premise of node energy, consider the optimum number of cluster head and selecting cluster node ,and through the use of limiter the number of nodes in each cluster to balance the energy depletion of each node. It could balance energy consumption and prolong the lifetime of sensor network through the use of algorithm. Emulation result indicates it is effective.
