Abstract:

As known, media access control (MAC) protocols for wireless sensor networks (WSNs) can exploit listen/sleep cycles to conserve energy. The relationship of the listen/sleep cycles and network performances is analyzed. An adaptive schedule medium access control (AS-MAC) for WSNs is presented. The adaptation of the cycles in MAC layer to the traffic is introduced. Simulations validate that the protocol can decrease the latency, improve the throughput and energy efficiency when traffic is dynamic.

Key words: wireless sensor networks, media access control, adaptation
