摘要:

通过分析节点休眠和网络性能之间的关系,提出了一种自适应的无线传感器网络媒体接入控制协议。仿真结果表明,在保证能量效率的同时,节点根据数据传送方向和负载大小自动调整唤醒的相位和周期,获得了良好的时延和吞吐量性能。

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
