In this paper, we exploit energy-efficiency and QoS-awareness for receiver-arbitrated and sender-predicted MAC Protocol (EQAP-MAC) in wireless sensor network. EQAP-MAC improves the transmission concurrency by separating control stream from data stream; minimizes energy consumption by sender by predicting receiver’s wake-up time; supports priority-based QoS through priority-based data flow selected, arbitrated and interrupted mechanisms; reduces transmission interference between the nodes by interleaving neighbor nodes’ wake-up time; improves system throughput and reduces the data stream transmitting delay by pipelining mechanism and optimizing send sequence. We have implemented EQAP-MAC on TinyOS and evaluated its performance on testbed. The result shows EQAP-MAC achieves higher concurrent performance and priority-based QoS guarantee with lower energy consumption compared with RI-MAC and X-AMC.

在本文中，我们针对无线传感器网络中的接收方仲裁和发送方预测 MAC 协议 (EQAP-MAC) 开发能量效率和 QoS 感知。EQAP-MAC通过将控制流与数据流分离来提高传输并发性；通过预测接收者的唤醒时间来最小化发送者的能量消耗；通过基于优先级的数据流选择、仲裁和中断机制支持基于优先级的 QoS；通过交错相邻节点的唤醒时间来减少节点之间的传输干扰；通过流水线机制和优化发送顺序，提高系统吞吐量，降低数据流传输延迟。我们已经在 TinyOS 上实现了 EQAP-MAC，并在测试平台上评估了它的性能。
