Adaptive dynamic channel allocation scheme for wireless multimedia communication systems

The traffic requirements from heterogeneous users in wireless multimedia communication vary in their data rate, arrival rate, and service time distribution. To provide efficient service, we propose a dynamic channel allocation strategy based on the traffic characteristics and channel utilization. Conventional channel allocation schemes are compared with the proposed dynamic channel allocation scheme. An analytic model is developed and a solution based on the moment-generating function technique is given. Numerical examples are also presented. The result shows that the scheme improves the system performance
