Energy Efficient Routing of Wireless Sensor Networks Using Virtual Backbone and life time Maximization of Nodes

Abstract

Different approaches have been proposed based on routing in WSN (Wireless Sensor Nodes) for Energy Efficient routing in Multi hop Networks and some localized based on geographical routing schemes have been also proposed. The key concept in virtual backbone scheduling is to minimize the energy consumption and more throughputs. To achieve QOS and fault tolerance of these backbone nodes in Multi hop Networks requires stable links. Hence existing localized routing in virtual backbone scheduling cannot guarantee the energy efficient routes. In this paper we propose an energy efficient routing for Virtual Back Bone Nodes (VBS) in which it maximizes the node life and turns off it’s radio when they are in sleep mode, in order to consume less energy. A concept of Restricted Back Bone Neighborhood Routing is proposed, which assures the efficient routing with minimum energy consumption of nodes and also implemented the critical transmission radius for Backbone nodes.
