Abstract?Extending network lifetime by energy efficient battery management is one of the most important research issues in the wireless sensor networks. Since sensor nodes are usually intended to be deployed in unattended or even hostile environments, it is almost impossible to recharge or replace their batteries. So, there are a lot of approaches that are designed to reduce the energy consumption of the wireless sensor nodes. In this paper, a new S-MAC -medium access control (MAC) designed for wireless sensor networks - named S-MAC protocol is proposed to reduce the energy consumption of the sensor nodes and to improve the performance of the sensor nodes in the wireless network compared to the Adaptive Listen Protocol, and Prolong Listen Protocol. It leads to lower average packet delay, higher throughput, lower average node energy consumption and longer average node lifetime.
