Abstract: 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.

Keywords: channel allocation; performance evaluation; wireless networks; bandwidth resources; QoS; quality of service; call blocking; handover dropping; channel utilisation.
