A hybrid routing protocol for wireless sensor network

Abstract

Routing protocols in wireless ad-hoc networks are not well suited for Wireless Sensor Networks as they have huge number of nodes, densely deployed and limited power processing and storage. Energy consumption of sensor nodes and their lifetime has become the major issues of Wireless Sensor Networks. This paper aims at building up of hybrid routing protocol based on PROUD and LEACH in Wireless Sensor Networks. For randomly generated nodes with different energy levels, cluster heads are chosen. Every other common node chooses its own cluster heads based on the available cluster choices and thus forming clusters. Cluster heads get sensed data from the common nodes and they send their aggregated data to the Base station for monitoring. So, node to node communication happens through cluster heads. Only cluster heads spend their energy for long range data transmission and thus avoiding energy consumption of other nodes. This procedure of head selection and cluster formation distributes the energy consumption among the nodes thus maximizing the lifetime of Wireless Sensor Networks by extending the life of the nodes. The proposed approach has been justified with results. © 2010 Springer-Verlag Berlin Heidelberg.
