Abstract
Energy effeciency of medium access control has been an active research area in wireless sensor networks since past few years. SMAC stands for Sensor-MAC protocol, which is designed on the basis of periodic listen-sleep mechanism of nodes for avoiding energy wastage because of idle listening. SMAC reduces energy consumptions because of collision, overhearing, control packet overhead and idle listening. This paper discusses the basic attribute of MAC protocols, their classification and the importance of SMAC protocol in wireless sensor networks. SMAC is developed primarily for Mote platform, and thereafter also implemented in Network Simulator-2.So without real hardware one can analyze the performance of SMAC under various application specific scenarios with NS-2.In this paper, the performance of SMAC protocol is analyzed under high and low traffic rates with different duty cycles in single hop scenario without the routing effect. The residual energy is also measured in each scenario. Since wireless sensor networks are application specific, so the behavior of SMAC is studied when the data transport performance and hence the throughput and jitter also plays an important role along with the energy effeciency. Finally it has been shown that under higher traffic loads, if the value of duty cycle is increased to optimum value, the residual energy of the node is improved with a better throughput.
