A self-adaptive prioritised hand-off DCA strategy for a microcellular environment

A complete traffic model and analysis for microcellular mobile systems with handoff using fixed channel allocation (FCA) is described. Only the new call arrival rate is supposed to be known and a method of assessing the hand-off arrival rate in each cell for any kind of traffic is derived. The analytical method is validated with a real non-uniform traffic distribution and is verified by simulations. An extension to the nonuniform compact pattern allocation algorithm is presented as an application of this analysis. Based on this extended concept, we propose a modified version of a dynamic channel allocation (DCA) strategy called compact pattern with maximised channel borrowing (CPMCB). It is shown that CPMCB is now a self-adaptive prioritised hand-off DCA strategy with enhanced performance that can be exploited in a PCS environment. The effect of user mobility on the grade of service is also considered by CPMCB.
