Abstract

In this paper, we suggest that the next generation wireless network is the integrated cellular and ad hoc network. We propose a call admission control scheme to support burst handoff call using the guard channel and relay function in next generation wireless network. We evaluate our scheme in terms of new call and handoff call blocking probability and channel utilization via simulation study. Simulation results show that our scheme offers better performance than the conventional schemes. In addition, it is also shown that our scheme may efficiently balance traffic load when the network is congested.
