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

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