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(AdaptiveSlotted Two-dimensional Probability Multi-channel and multi-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.
Aiming at the problem that the transmission probability p1 and detection probability p2 can not be adjusted in the slotted two-dimensional probability-based CSMA random access protocol, the throughput of the CSMA is reduced under the condition of heavy load, an adaptive multi-channel two This paper analyzes the throughput of the load balancing wireless communication network system under the protocol by using Markov chain analysis method. Volume and throughput of each priority analytic results.The simulation results show that the theoretical analysis and simulation experiments are consistent and reasonable.Through the simulation with time-slot two-dimensional probabilistic access protocol shows that the system has better performance .
