A Wireless Sensor Network (WSN) consist of battery operated sensing and computing devices deployed for monitoring applications. With the advent of new technologies WSNs are providing a new class of information to human beings. In most cases the networks were stationary but as a evolutionary step the WSNs have to consider mobility. This new class of sensor networks is Mobile Wireless Sensor Networks. eg. moving robots, surveillance aircrafts. Nodes share a communication channel for communication. To share communication channel the establishment of a MAC protocol is required in the sensor nodes. The objective of the MAC protocol is to regulate access to the shared wireless medium.
