Abstract: Wireless Sensor Networks (WSNs) in the zone time alter to more engaging and broaden their way into immense variance of exercising in different domains. Elevation in wireless sensor network technologies provide the affability of small and low-cost sensor nodes with the adequacy of sensing, processing, computing the physical and environment circumstances. Due to inhibitionin transmission range, processing and energy resources it is requisite to design impressive and energy aware protocol to enhance network lifetime.Routing techniques are develop to increase life cycle of sensor network and enhance throughput performance. This paper gives, an analysis of different routing strategies used in wireless sensor networks further importance of cluster based routing, types of cluster, classification of cluster based routing are discussed. The study concludes with the issues and the resent researchers on cluster based routing.

Keywords: Wireless Sensor Network, Routing Schemes, Clustering-based Routing.
