摘要: 针对时隙式二维概率型CSMA随机多址接入协议中,发送概率p1和检测概率p2不可调整,在重负载的情况下,其吞吐量下降的问题,提出了一种自适应多通道二维概率型时隙式随机多址接入协议(Adaptive Slotted Two-dimensional Probability Multi-channelandmulti-access).用马尔可夫链的分析方法分析得到了该协议下负载均衡型无线通信网络系统的吞吐量和各优先级吞吐量的解析结果.仿真实验结果表明理论分析和仿真实验的一致性与合理性.通过与时隙式二维概率型接入协议的仿真比较说明该系统具有较好的性能.Abstract: The multi-channel and slotted random multiple-access(MSRM) protocol has poor throughput under heavy loads,because the transmitting-probability p1 and detecting-probability p2 can't be adjusted with load.Aadaptive two-dimensional probability multi-channel and slotted random multi-access(ATPMSRM) protocol is proposed for wireless communication networks.It is analyzed the systemic throughput of ATPMSRM protocol along with the result of throughput based on priority with Markov Chain.The results are shown that the computer simulation is in concordance with the theoretical analysis.Furthermore,the comparing results with MSRM protocol show the ATPMSRM protocol is superior.
