  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 energy-efficient MAC protocol, Sensor-MAC based on IEEE 802.11 protocol. In this paper, which has energy efficient scheduling, was proposed. In this paper, we propose Dynamic S-MAC that is dynamically operated by network-traffic states. Dynamic S-MAC protocol improves energy consumption of S-MAC due to change the frame length according to network-traffic states. Using NS-2 Simulation, we compare the performance of Dynamic S-MAC with S-MAC protocol.
