Abstract

We investigate the impact of user mobility an the performance of interference adaptive (IA) dynamic channel allocation (DCA) schemes. The results have been achieved by means of a simulation tool that takes propagation, mobility, interference, traffic and channel allocation into account. We propose a partially distributed algorithm and compare its performance with that of well known totally distributed IA-DCA schemes (LIA and LTA). Simulation results show that the proposed algorithm outperforms LIA for all the values of offered traffic considered
