广播通信融合网络能效分析
发布时间：2018-09-09 12:44
【摘要】：针对广播通信融合网络的性能分析问题,提出了一种新的系统模型及能效分析方法。从用户请求业务角度出发,将请求的业务分类为热门与非热门业务。并基于随机空间网络模型,将融合网络中的蜂窝基站与用户建模为2个独立的空间泊松点过程(PPP)随机分布,而广播大塔位于服务区域中心。通过考虑广播网的覆盖范围及蜂窝网的中断概率推导出广播与通信融合网络下系统的能量效率(EE)闭合表达式,进一步讨论热门业务概率对融合网络能效的影响。仿真结果表明,基于讨论的融合系统模型,并考虑了通用场景下的基站和用户密度,当热门业务超过总业务的5%后,融合网络能效相比于单蜂窝网络有显著提高。这种新的系统模型及能效分析方法为后期分析融合网络总体性能奠定了基础。
[Abstract]:A new system model and energy efficiency analysis method are proposed for the performance analysis of broadcast communication fusion networks. From the point of view of user request service, the requested service is classified as hot service and non hot service. Based on the stochastic spatial network model, the cellular base station and the user in the fused network are modeled as two independent spatial Poisson point processes (PPP), while the broadcast tower is located in the center of the service area. By considering the coverage of broadcast network and the outage probability of cellular network, the (EE) closed expression of energy efficiency in broadcast and communication fusion network is derived, and the influence of the probability of hot traffic on the energy efficiency of fusion network is discussed. The simulation results show that, based on the discussed fusion system model and taking into account the base station and user density in the general scenario, when the hot traffic exceeds 5% of the total services, the energy efficiency of the fusion network is significantly higher than that of the single cellular network. The new system model and energy efficiency analysis method lay the foundation for the later analysis of the overall performance of the fusion network.
