HANDOVER AND DYNAMIC CHANNEL ALLOCATION TECHNIQUES IN MOBILE CELLULARNETWORKS

This paper deals with an efficient Dynamic Channel Allocation (DCA) te chnique applicable to terrestrial mobile cellular networks. A channel (or resource) is a fixed frequency bandwidth (FDMA), a specific time-s lot within a frame (TDMA), or a particular code (CDMA), depending on t he multiple access technique used, A cost function has been defined by which the optimum channel to be assigned on demand can be selected, I n addition, a suitable mobility model has been derived to determine th e effects of handovers on network performance, The performance of the proposed DCA technique has been derived by computer simulations in ter ms of call blocking and handover failure probabilities, Comparisons wi th the classical Fixed Channel Allocation (FCA) technique and other dy namic allocation algorithms recently proposed in the literature have b een carried out to validate the proposed technique.
