Abstract

Wireless sensor networks consist of sensor nodes which are expected to be battery-powered and hard to replace or recharge. Thus, reducing the energy consumption of sensor nodes is an important design consideration in wireless sensor networks. For the implementation of an energy-efficient MAC protocol, sensor-MAC based on the IEEE 802.11 protocol, which has energy efficient scheduling, was proposed. In this paper, we propose dynamic S-MAC that adapts dynamically to the network-traffic state. The dynamic S-MAC protocol improves the energy consumption of S-MAC by changing the frame length according to the network-traffic state. Using the NS-2 Simulator, we compare the performance of dynamic S-MAC with that of the S-MAC protocol.
