Abstract: For wireless sensor networks reducing the consumption of energy source has turn primary motivation for researcher. Energy efficient measures are essential at node level as well as process level in order to achieve fast transmission, minimum delay and least energy digestion. In wireless networks, radio operation is responsible for maximum energy breakdown. The MAC layer primarily handles channel and radio communications. The work carried in this paper, mainly proposes a novel scheme MD-SMAC (Modified Sensor MAC) at MAC layer that results in minimization of energy consumption in the wireless sensor networks. Our proposed scheme basically emphasize on sleep and listen schedules of the sensor nodes specially the periodic synchronization phase. Moreover, unlike SMAC, the nodes set aside in communication need to wake up less frequently allowing energy conservation in remaining sensor nodes. It results in preserving not only energy constraints but also packet delivery, throughput and delay. For simulation we have used NS2.35 tool and the experiment at ion results reveals the MD-SMAC scheme as effectively enhancing energy efficiency over S-MAC and demonstrate the enhancements by representing significant performance.
