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.
A performance analysis method is proposed for 3G / ad hoc networks.The attenuation relationship between received power and path is based on natural path loss and shadow fading.Firstly, the application scenarios of 3G / ad hoc networks are briefly introduced. Then, based on the application scenarios of this network, several performance analysis methods are proposed to calculate the performance indexes such as the outage probability, dropped call rate and the new call user congestion rate of the converged network. Then, the corresponding performance formula is deduced and compared with the traditional 3G network The above performance is compared.At the same time, the capacity formula of the converged network is derived based on the outage probability of the converged network.The simulation results show that the 3G / ad hoc converged network performs better than the traditional 3G network in the above performance, hoc can effectively improve its system performance.This performance analysis method can be used for the planning and optimization of 3G / ad hoc converged networks.
