Wireless sensors networks are potentially employed in various fields such as defense system, target tracking, target monitoring, wildlife monitoring and disaster management. The node's of a wireless sensor network consists of three main parts-processor, transmitter/receiver and memory unit. For these parts to be operational in an efficient way, the battery power of the nodes must be prolonged and utilized effectively. Idle listening, control data overhead, collisions, retransmission are the

Further, the idle time is considerably eliminated by adapting a central memory register for making reservations on receivers. The node's will be active only when needed and sleep rest of the time. Collision avoidance and energy loss due to retransmissions are addressed substantially in RR-MAC design. Since the collisions are reduced, the data can be sent with minimized time delay caused by retransmissions.
