In this paper we have proposed a novel three phase approach for energy efficient routing using multipath routing and clustering technique. In Wireless sensor network (WSN), sensor node has limited battery supply and transmission range, so it can not directly communicate with sink node. Hence, multi-hop and multi-path communication is essential. In case of single path routing, if single node on a routing path dies then the whole communication will fail. Thus multi-path routing is more suitable to make the network fault tolerant. Here, we use multipath ring routing protocol in which multipath is available from all rings except ring R1, i.e. direct neighbour of sink node. We have used enhanced overlay scheme to provide the advantage of multipath routing to nodes of ring R1. To support scalability and remove redundancy of data, clustering is an effective technique to minimize network traffic which will ultimately improve network lifetime. We have used LEACH protocol for clustering. We have simulated proposed three phase approach using Castalia simulator. We observed that proposed approach is more energy efficient and robust in terms of data delivery than the multi-path ring routing.
