Abstract:

An analytical approach to evaluate the performance of the 3G/ad hoc integrated network is presented. A channel model capturing both path loss and shadowing is applied to the analysis so as to characterize power falloff vs. distance. The 3G/ad hoc integrated network scenario model is introduced briefly. Based on this model, several performances of the 3G/ad hoc integrated network in terms of outage probability, call dropping probability and new call blocking probability are evaluated. The corresponding performance formulae are deduced in accordance with the analytical models. Meanwhile, the formula of the 3G/ad hoc integrated network capacity is deduced on the basis of the formula of the outage probability. It is observed from extensive simulation and numerical analysis that the 3G/ad hoc integrated network remarkably outperforms the 3G network with regards to the network performance. This derived evaluation approach can be applied into planning and optimization of the 3G/ad hoc network.

针对3G/ad hoc融合网络提出了一种性能分析方法.接收功率与路径的衰减关系基于路径的自然损耗与阴影衰落.首先, 对3G/ad hoc融合网络的应用场景模型进行了简要的介绍.然后, 基于此网络的应用场景, 提出了几种性能分析方法来计算融合网络的中断概率、掉话率、新呼叫用户拥塞率等性能指标, 随后推导出相应的性能公式并与传统3G网络的上述性能进行了比较.同时, 基于融合网络的中断概率推导出融合网络的容量公式.仿真结果表明3G/ad hoc融合网络比传统的3G网络在前述性能方面表现得更好, 3G网络中引入ad hoc能够有效地提高其系统性能.本性能分析方法可以用于3G/ad hoc融合网络的规划与优化.
