摘要
混合无线网络是在 Ad hoc 网络中添加基站的新型网络模型,其容量是评估网络性能的重要参数。本文研究了混合无线网络的容量问题。首先建立了该网络的网络模型,在考虑延迟时间的基础上提出一种新的路由策略,一定程度地保证了数据传输的实时性。在此基础上运用图论中数学计算的方法推导了混合无线网络容量数学期望的分析表达式,这是本文的重要结论.对于未来混合无线网络的设计与分析都具有指导意义。
Hybrid wireless network is a novel network model, where a sparse network of base stations is placed within an Ad hoc network. Capacity on hybrid wireless network is an important parameter to evaluate the network performance. In this paper, we study about the capacity of hybrid wireless networks. We establish a hybrid wireless network model and propose the new routing policy based on the delay, which assures the real-time transmission to some extent. By our model, we derive the analytical expressions of mathematical expected value on the capacity in a hybrid wireless network according to the graphics computing, which is the main contribution of this paper that has the directive significance to design and analyze hybrid wireless networks in the future.
