Abstract

The hybrid wireless network is a kind of the novel network model, where a sparse network of base stations is placed within an ad hoc network. The problem on throughput capacity of hybrid wireless networks is considered to evaluate the performance of this network model. In this paper, we propose a general framework to analyze the capacity of hybrid wireless networks in code division multiple access scheme. Subsequently, we derive the mathematical analytical expressions of the capacity of hybrid wireless network systems under some assumptions. Finally, simulation results show that the hybrid wireless network could be a tradeoff between centrally controlled networks and ad hoc networks.
