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 major problems which reduce the energy efficiency in the nodes. This paper aims at proposing and analyzing RR-MAC protocol (Receiver-Reservation MAC protocol) which uses dynamic multichannel and time division algorithm to enable nodes utilize energy in efficient manner.
