Wireless Sensor Networks (WSNs) are wireless networks consisting of a group of small, inexpensive nodes, which collect and disseminate significant data. Nodes in a wireless Sensor Networks have various energy and computational constraints due to their inexpensive, random method of deployment. Wireless sensor networks are utilized in a wide range of applications including battlefield surveillance, smart home environments, habitat exploration of animals and vehicle tracking. Energy Efficiency is one critical issue for  wireless sensor networks because many sensors are equipped with batteries that have limited life time. This paper introduces the concept of combining two Medium Access Control (MAC) Protocols such as spatial correlation based collaborative medium access control (CCMAC) and Hybrid Medium Access Control (HMAC) which will increase the energy efficiency of the Network. The four various routing protocols explored in this work are AOMDV,AODV, DSR,DSDV. In this paper, comparison of energy efficient routing protocols for Wireless Sensor Networks using spatial correlation based collaborative medium access control (CCMAC) combined with Hybrid Medium Access Control (HMAC) is proposed. Simulation results have been obtained by using Ns2. From the results, the performance of AOMDV is better compared to the other three protocols such as AODV,DSR and DSDV.
