针对节点具有多个可用信道的自组网,提出了一种基于负载均衡的多信道MAC接入协议,协议采用按需预约的方式进行动态信道分配,通过携带在信道预约消息中的节点邻居状态信息实现节点信道状态的更新。在协议开销增加很小的情况下,每个节点只需要一部半双工收发信机就能够实现在多个信道上高效的数据收发,不需要节点间的时钟同步,极大的降低了对网络节点设备的硬件要求,具有良好的应用前景。仿真结果表明,协议在网络总吞吐量、端到端时延等方面具有优良的性能。
Aiming at the ad hoc network with multiple available channels for nodes, a multi-channel MAC access protocol based on load balancing is proposed. The protocol adopts on-demand reservation for dynamic channel allocation. Through the neighbor status of nodes carried in the channel reservation message, Information to achieve node channel status updates. With a small increase in protocol overhead, each node only needs one half-duplex transceiver to send and receive data efficiently on multiple channels without the need for clock synchronization between nodes, which greatly reduces the number of pairs Network node equipment hardware requirements, has a good application prospects. Simulation results show that the protocol has excellent performance in terms of total network throughput, end-to-end delay and so on.
