摘要:

由于新的无线应用的出现和场景的复杂性,无线网络中的业务变得多样化,并且在空间和时间上都是波动的。本文的目的是定量地分析无线业务的影响,在空间和时间上的波动,对无线网络的性能。特别是,我们建议结合随机几何和排队论的工具来模拟交通的空间和时间波动,据我们所知,很少有分析评估。我们推导了空间和时间统计,总到达率,队列的稳定性和用户的延迟考虑两个不同的空间特性的流量,即,均匀分布和非均匀分布的情况。数值结果表明,虽然用户成簇时的流量波动(反映在总到达率的方差上)比用户均匀分布时剧烈得多,但不稳定概率较小。本文的工作为考虑业务量复杂时空波动的无线网络设计提供了参考。

英文摘要:

The traffic in wireless networks has become diverse and fluctuating both spatially and temporally due to the emergence of new wireless applications and the complexity of scenarios. The purpose of this paper is to quantitatively analyze the impact of the wireless traffic, which fluctuates both spatially and temporally, on the performance of the wireless networks. Specially, we propose to combine the tools from stochastic geometry and queueing theory to model the spatial and temporal fluctuation of traffic, which to our best knowledge has seldom been evaluated analytically. We derive the spatial and temporal statistics, the total arrival rate, the stability of queues and the delay of users by considering two different spatial properties of traffic, i.e., the uniformly and non-uniformly distributed cases. The numerical results indicate that although the fluctuation of traffic (reflected by the variance of total arrival rate) when the users are clustered is much fiercer than that when the users are uniformly distributed, the unstable probability is smaller. Our work provides a useful reference for the design of wireless networks when the complex spatio-temporal fluctuation of the traffic is considered.
