The simulation and analysis of LEACH protocol for wireless sensor network based on NS2

The typical routing protocol of wireless sensor network is Low Energy Adaptive Clustering Hierarchy (LEACH) protocol, which uses self organizing and dynamic cluster formation, so it has a problem that more or less cluster headers may have a bad effect on the network. This article will discuss that the quality of network can be optimized through controlling the number of cluster headers in LEACH protocol via the NS2 simulation, and then illustrate that setting optimal cluster headers can lower energy consumption and extend the lifecycle of network.
