Handoff is one of the key elements in ensuring quality of service (QoS) in mobile wireless networks. Handoff connections generally have higher priority than new connections. Traditional reservation policies that reserve some channels for handoff connections are not adaptive to traffic load changes. This paper proposes a new Dynamic Guard Channel (DGC) scheme, which (1) combines differentiated QoS service model and priority handoff mechanism; (2) provides fairness for differentiated QoS services; (3) adapts to various traffic loads because it adopts passive feedback mechanism if we assume a stationary distribution for the mean arrival times; (4) does not need to exchange state information among different cells, so it is easy to implement and is simple enough to be used in real world scenarios; (5) utilizes network resource efficiently and puts a bound on each service blocking probability. The simulation results show that the ratios among different QoS service probabilities are guaranteed to predefined values and system utilization is improved.
