Analysis of channel allocation scheme for wireless cellular networks

Compared to wired networks, the communication bandwidth in the wireless networks is limited. In trying to achieve QoS guaranteed wireless services, efficient utilisation of bandwidth resources becomes a fundamental issue. A number of channel allocation schemes have been proposed to fully utilise the wireless bandwidth, but many of them just proposed the channel allocation scheme without presenting a specific channel allocation model. In this paper, we propose and analyse three different channel allocation schemes for wireless networks. We build three system models based on a two-dimensional Markov chain to compute the performance of base station in terms of the new call blocking probability, the handover dropping probability, and the channel utilisation.
