摘要
提出了一种基于TDMA的多信道MAC协议,采用动态变更子帧长度、控制信道与数据信道时域重合方式,尽可能提高时隙资源利用率,采用协商机制,有效降低分组冲突,保证网络吞吐量、时延等性能指标.在OPNET仿真平台中建模,该协议在网络负载较高时,仍然可以保证分组传输成功率和较低的时延,为Ad hoc网络的设计提供参考.
This paper studies and designs a multi-channel MAC protocol based on TDMA. In order to improve the utilization ratio of resource as far as possible, this protocol could change the length of the subframe dynamically and make control channel and data channels overlap in the time domain. The negotiation mechanism is adopted to reduce the packet conflict effectively, ensure the network throughput and delay. By modeling in the OPNET simulation platform, when the network load traffic is high, the packet transmission success rate and low latency can be guaranteed to provide reference for the design of Ad Hoe network.
