Simulation and Performance Analysis of Dynamic Channel Allocation Algorithms in DECT
The 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. It has easy initialization and is adaptive to the slowly changing environment. It is flexible. A port can utilize all the channels available to the system. It is adaptive. The port can adjust the channel allocation automatically to the slowly changing environment. It is stable, simple and fully distributed. Simulation shows that it has twenty five percent improvement over the U.K. DECT Test Bed DCA  and sixteen percent improvement over the Channel Segregation DCA   in terms of system capacity in a given environment.
