多跳Ad hoc网络最佳吞吐率量化分析模型

确定无线网络的系统吞吐率是有效利用其传输各种类型数据的前提，目前关于无线网络吞吐率的研究大多是基于基础接入点模式的一跳接入系统吞吐率．由于多跳连接的Ad hoc网络系统吞吐率受很多因素的影响，因此准确估计多跳连接的Ad hoc网络容量是一项十分复杂的工作．提出了一种综合考虑各种因素的Ad hoc网络最佳吞吐率量化分析模型，在系统建模过程中同时考虑了受隐藏节点效应影响与载波监听范围影响的节点碰撞概率，且在对系统行为分析过程中考虑了捕获功能的存在，使得理论分析模型更加准确．

Quantized optimal throughput analysis model of wireless multi-hop Ad hoc networks

Knowing the systematic throughput of a wireless network is an important thing before it can be efficiently used.Researches on the maximum throughput of a wireless network are mainly based on the fundamental network architecture in which nodes usually access the access point via one hop.The optimum throughput of the multi-hop Ad hoc network is related to network topology,node density,carrier sense range,hidden node effect and capture function and so on;so,the accurate estimation of it is a complicated job.An integrated analytical model which takes all the above factors into consideration is presented here.The modeling process involves the collision probability caused by both the hidden nodes and the nodes within the carrier sensing range;besides,it considers the capture function’s existence,which makes the analytical model more accurate.Through numerical analysis and network simulation,the newly deduced analytical model is proved to be able to match the practical results very well.
