Performance evaluation of multi-guard channel schemes in broadband mobile networks

In this paper, we proposed two Multi-Guard Channel Schemes (MGCS) for multi-threshold and multirate services. The purpose of MGCS is proposed to guarantee the quality of service for multimedia wireless cellular networks. Another contribution of this paper is to develop two generalized analytical models, two-dimensional Markov chain model, to investigate the performance of two proposed scheme and compared them with each other. The analytical results show that MGCS 2 achieves better results on the handoff dropping probability and new call blocking probability.
