Abstract

Channel allocation is one of the fundamental problems faced by designers of the portable communication systems. A Distributed Dynamic Channel Allocation (DDCA) algorithm is proposed. The DDCA combines the advantages of both the fixed and the dynamic channel allocation algorithms in an effective way. Initialization is easy and it is adaptive to slowly changing environments. It is flexible. A port can utilize all the channels available to the system. It is adaptive to slowly changing environments so that the port can adjust the channel allocation automatically when ports are added or removed from the system. It is stable, simple and fully distributed. Simulation shows that it has 25% improvement over the UK DECT testbed DCA and 16% improvement over the Channel Segregation DCA in terms of system capacity with one percent of grade of service
