在无线传感器网络中，媒体访问控制（MAC）协议是关键技术之一.网络协议旨在保证网络通信的正常进行。与传统的MAC协议相比，传感器上电池能量的有限性决定了传感器网络MAC协议以节能为主要设计目标。本文提出了一种基于业务队列的竞争窗口自适应MAC协议--QA-MAC协议，该协议基于传感器MAC（SMAC）协议，根据当前业务队列的大小和变化自适应地调整竞争窗口大小，仿真结果表明，与现有的S-MAC协议相比，QA-MAC协议可以节省28.7%的能量。该方法特别适用于高速网络。
In wireless sensor networks¿Cthe Media Access Control (MAC) Protocol is one of the key. Network Protocols designed to ensure the normal network communications. Compared with the traditional MAC Protocol, limited battery energy on sensors determines the sensor network MAC Protocol to be energy-efficient of the Primary design goal. This Paper Proposes a contention window adaptive MAC protocol based traffic queue, the QA-MAC protocol, which is based on sensor MAC (SMAC) protocol, adaptive adjustment of contention window size according to current traffic queue size and Varying, Our simulated result shows that comparing with existing S-MAC protocols, QA-MAC obtains 28.7% energy savings. This method is especially suitable for high-speed network.
