摘要:

分析了两跳中继算法在移动自组织网络中的时延性能.通过计算几何随机过程的平均转移步数和随机变量联合概率密度分布,得到了传递时延上界的闭合表达式,并给出了最优发送副本数;基于平均剩余服务时间,对端到端时延性能进行了理论推导;给出数值仿真结果,直观地展现了时延性能随网络规模和业务负载的变化趋势.

关键词: 时延性能分析, 移动自组织网络, 两跳中继算法

Abstract:

The delay performance of mobile Ad hoc networks with two-hop relay algorithm is analyzed. Computing the mean transition steps of the geometric random process and joint probability distribution of random variables, the closed-form expression of the delivery delay upper bound and the optimal transmission redundancy strategy are obtained. Further, based on mean residual service time, the end-to-end delay performance is derived. Finally, the numerical results show the relationship of delay performance with the network size and the traffic load.

Key words: delay performance analysis, mobile Ad hoc networks, two hop relay algorithm
