Wireless Sensor Network (WSN) has played an important role in the area of environment, agriculture monitoring, traffic control, disaster management etc. Large number of low cost sensor nodes is distributed in specific area of interest such that nodes can communicate with each other. WSN networks have two classifications: structured and unstructured. In structured WSN the position of placing the nodes are predetermined so that perfect coverage is provided. In unstructured WSN the nodes are placed in ad-hoc manner. Sensor nodes are operated by small battery that consumes lot of energy during transmission of signal so energy efficiency is one of the main criterions for designing any MAC protocol.
