自适应二维概率型随机多址无线网络协议分析

从提高无线通信网络QoS角度,提出了一种自适应二维概率型随机多址接入协议,协议根据通道负载的轻重,自适应地动态调整二维概率型随机多址协议中概率p_1、p_2取值.保证系统有较高的通道利用率,使系统吞吐量性能随着负载变化始终保持在最优状态.通过分析控制协议下系统吞吐量解析结果,仿真结果表明理论分析和仿真实验的一致性与合理性.同时,仿真实验给出了连续时间型系统与时隙式系统的比较结果,说明时隙式系统有较优性能.

Analysis of Two-dimensional Probability Self-adaptive and Multi-access Wireless Network Protocol

To provide a higher QoS for wireless communication network,this paper presents a Two-dimensional Probability Self-Adaptive and Multi-access (TPSAM) protocol,system self-adaptively adjusts value of two parameters p_1 and p_2 according to channel load G,which realizes high utilization of channel and ensures the best QoS performance.To analyze the systemic throughput of TPSAM protocol,the results show that the computer simulation is in concordance with the theoretical analysis.Furthermore,the comparing results with continuous-time system show the slotted system is superior.
