摘要
在无线传感器网络体系结构中,MAC(medium access control)协议是保证网络高效通信的重要协议.无线传感器网络有着与传统无线网络明显不同的性能特点和技术要求,传统无线网络MAC协议无法应用于传感器网络,各种针对特定传感器网络特点的MAC协议相继提出.归纳无线传感器网络MAC协议的设计原则和分类方法,分析当前典型的各类MAC协议的主要机制,详细比较这些协议的特点、性能差异和应用范围.最后总结无线传感器网络MAC协议的研究现状,指出未来的研究重点.
In wireless sensor network, medium access control (MAC) has been at the core of effective communication. Since the traditional MAC layer protocols don't adapt themselves to the performance traits and technique request of wireless sensor network, many MAC protocols for wireless sensor network are studied. Design principles and classification methods for MAC protocols in wireless sensor network are summarized, and fundamental mechanism of each recent representative MAC protocol is analyzed in detail. The characteristics, performance, and application areas of various MAC protocols in wireless sensor network are adequately compared. Finally, the status of current research development are concluded and the open research issues on MAC layer design are pointed out.
