Abstract :
In this paper, we propose a distributed energy-saving strategy by dynamically switching-off wireless network interface card (NIC), and analyze its performance in fully connected networks. Simulation results show that in wireless LAN, when the network load is rather heavy, this scheme can save NIC´s energy consumption by more than 60%, at the meanwhile, its delay and throughput performance is still similar to that of 02.11DCF protocol. This scheme does not need global synchronization and can be applied to other MAC protocols based on collision avoidance mechanism.
