An energy efficient improved RPL routing protocol

For battery powered wireless sensor networks, energy is the vital resource. The challenging problem is to make a protocol which is an energy efficient. In this paper, the drawbacks of the IPv6 Routing Protocol for Low power and Lossy networks and the energy dissipation and energy load balance problems of routing protocol RPL are overcome. An improved and relatively balanced routing protocol (IRPL) is developed based on an efficient clustering algorithm. The optimal number of clustering heads can be determined by assuming network model. And the clustering process in wireless sensor network can be completed by integrate the node competition mechanism and clustering probability model by using the cluster head node. In the control model, the wireless sensor network was split into concentric rings and each concentric ring is having equal area. In this paper the optimal forwarding communication area is considered based on different levels of concentric ring domain which determines the best network route. Our experimental simulation results shows that the IRPL routing protocol can reduce overall network energy consumption, significant improvement in energy balance and network lifetime.
