Abstract :
In recent years, with the developments of wireless sensor networks technology, how to prolong the lifetime of WSN and reduce energy consumption by the sensor nodes becomes a hot topic. This article analyzes the mechanism of clustering in LEACH protocol and presents improved approaches based on energy of sensor node and the distance between the node and the base satation, then compares their performances. Results of simulation indicate that the improved protocols can balance the network load and prolong the network lifetime.
