Capacity and Delay in Hybrid Wireless Networks

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.
