In Modern communication systems, design and development of wireless sensor network plays a very decisive role, principally for broadcast communication. In order to extend battery life of wireless network and to increase energy efficiency, implementation of MAC protocol with respect to overhearing, packet collision, sleep and idle listening duration. In this paper, Random Interference Medium Access Control (RI-MAC) protocol is implemented, in that way taking into consideration random slot assignment in each MAC frame, along with knowledge of neighbors' transmission schedules. Network is simulated by using NS-2 software. Results show that RI-MAC conserves energy, transmits messages fairly among the nodes in the system, and is adaptive to changes in the topology.
