| 摘 要： | 为了减小M2M网络中MAC层的接入冲突,提高接入数据传输效率和节点能量利用效率,提出了一种新的混合分组协议HG-MAC(Hybrid and Grouping MAC)。HG-MAC混合利用基于调度与基于竞争的两种接入方式；对节点进行分组分层管理,减少接入冲突和提供QoS保障；采用休眠机制提高能量利用效率；引入动态调整机制和可变帧长度提高协议灵活性。通过建立二维马尔可夫链,对竞争时长与数据传输速率之间的关系进行了理论分析。利用OPNET仿真工具,将HG-MAC与CSMA/CA和TDMA的性能进行了仿真比较。结果表明HG-MAC在数据传输速率、能量效率和信道利用率上具有一定的优势。

| Abstract: | To decrease collision and improve energy efficiency in M2M network, a Hybrid and Grouping MAC (HG-MAC) is proposed. Through consisting of contention-based protocol and schedule-based protocol, dormancy mechanism is used to save energy. Devices are grouped and graded to reduce collision and offer QoS guarantee. To improve flexibility, dynamic adjustment is used. To research the influence of COP duration on HG-MAC, two dimensions Markov chain is used to analyze the relationship of data transmission rate and COP duration. Through the simulation used OPNET, HG-MAC is contrasted with CSMA/CA and TDMA. The simulation results demonstrate the effectiveness of the proposed HG-MAC protocol. The simulation results demonstrate the HG-MAC protocol is better than others in data transmission rate, energy efficiency and utility. |
