An adaptive multi-guard channel scheme for multi-class traffic in cellular networks

Abstract

In this paper, an adaptive channel reservation scheme for multi-class traffic is proposed to ensure the quality of service for multimedia wireless cellular networks. Although different numbers of guard channels are reserved for the handoff calls of different traffic classes, new calls can access these channels with a certain probability determined by the mobility of calls and channel occupancy. We develop a generalized analytical model to investigate the performance of the proposed scheme. Compared with the traditional well-known FSS scheme, the analytical results show that our scheme achieves better results on the handoff dropping probability, new call blocking probability, and grade of service (GoS).
