摘要：Wireless Sensor Network (WSN) has been considered as a promising method for reliably monitoring civil and military environment in hazardous or dangerous conditions. Usually, sensor webs consisting of nodes with limited power and limited wireless communications are deployed to collect useful information from the field. Due to these reasons, how to improve energy efficiency is a critical issue for WSN protocols. The Low- Energy Adaptive Clustering Hierarchy (LEACH) protocol puts forward an algorithm where sensor nodes are built into clusters to fuse data before transmitting to Base Station (BS). An improved version of LEACH, called Low-Energy Adaptive Clustering Hierarchy- centralized (LEACH-C), is presented, where the central Base Station (BS) executes the clustering to improve energy efficiency. This paper presents an improvement of LEACH-C based on power, called Low-Energy Adaptive Clustering Hierarchy-central constrained (LEACH-CC), which balances energy distribution of network by means of changing range of nodes being cluster head. Stimulation results show that LEACH-CC can improve system lifetime over its comparatives.
