Improvement of Routing Protocol LEACH in Wireless Sensor Network

Abstract

Abstract:

Abstract: Classic clustering algorithm LEACH is widely used in wireless sensor networks, but does not consider energy of cluster head and position, so the network consumes energy greatly. To save energy of node and extend the life of network, on the basis of the LEACH algorithm, we proposed the improved LEACHi. The LEACHi adds energy and distance references in the election expression of cluster head, so the nodes which have more energy can be cluster head. On experimental simulation platform of the NS2, the LEACHi algorithm is compared with LEACH algorithm. The results show that the network energy consumption is greatly reduced, and the network life cycle is extended.
