This paper proposes medium access control (MAC) layer protocol for wireless sensor networks. Sensor nodes are battery operated so the energy efficiency is an important aspect for the wireless sensor networks WSNs. The protocol aims for achieving energy efficiency to increases network lifetime and scalability to increase the network capacity. Clustering, synchronization and low duty cycle are some of the characteristics for utilizing energy efficiently in the network. The protocol is designed with having the schedules of the clusters to be overlapped in a low duty cycle operation. We have evaluated the performance of protocol through detailed ns- 2 simulation. The simulation results show that this protocol outperforms when compared to SMAC. It has reduced schedule updates, power consumption and data loss. . Keywords— Wireless sensor networks, duty-cycle, clustering, schedule, synchronization, energyefficiency
