| 摘要: |
| 在无线传感网(WSN)体系结构中，介质访问控制(MAC)协议负责调配网络中节点的信道接入，具有保障网络高效通信的重要作用。混合类MAC协议综合了竞争类MAC协议以及调度类MAC协议的特点，在融合两种机制的优点的同时克服其缺点，为无线信道资源的分配提供了更加灵活和全面的策略。首先概述了无线传感网MAC协议设计要点及分类，然后重点分析了无线传感网中经典的混合类MAC协议及国内外前沿的研究进展，并进一步归纳对比了各协议运行机制、性能及不足，得出混合类MAC协议的应用相关性及差异性的结论，最后总结了无线传感网混合类MAC协议研究现状并指出了未来的研究重点，以期为相关领域的研究人员提供参考。 |

| Abstract: |
| In wireless sensor network(WSN) architecture,media access control(MAC) protocol plays an important role in the deployment of wireless channel for network nodes and ensuring effective communication. Hybrid MAC protocol is a combination of contention based and schedule based MAC protocol and this hybrid mechanism can benefit from the merits of both schemes while mitigating their drawbacks. As a result,it provides with a more flexible and comprehensive strategy for wireless channel resource’s allocation. Firstly,this paper introduces the design essentials and classifications of MAC protocols,and then analyzes some classical and cutting-edge research on hybrid MAC protocols in detail. Secondly,it compares the mechanism,performance and drawbacks of these different protocols,and the feature of application relativity and diversity. Finally,it summarizes the status of current research and open research issues on hybrid MAC protocol design. The information in this paper can provide reference for those engaged in related field. |
