Dynamic channel allocation in wideband cellular communication networks

Future telecommunication systems will integrate “wireline” and “wireless” networks in a single advanced infrastructure, and it is expected that such systems will exploit asynchronous transfer mode (ATM) technology. This paper considers some aspects of this integrated telecommunication infrastructure. In particular, we propose and analyze an improvement, for wired networks, of the virtual connection tree (VCT) concept, while for the wireless part, a new model for the analysis of a dynamic channel allocation scheme is presented. The obtained analytical results, confirmed by simulation in a wide range of load conditions and user mobility, allow us to evaluate the main system performance parameters, in terms of blocking probability of new calls, handoff blocking probability and forced termination probability
