Effect of Blocking Probability on Channel Allocation Using Distributed Dynamic Channel Allocation Algorithm

Technological advances and rapid development of handheld wireless terminals have facilitated the rapid growth of wireless communications and mobile computing. Essentially we have a limited resource transmission spectrum, which must be shared by several users. Since the available frequency spectrum is limited the channels must be reused as much as possible in order to increase the system capacity. This requires a proper channel allocation scheme. The role of a channel allocation scheme is to allocate channels to cells or mobiles in such a way as to minimize call blocking or call dropping probabilities. The process of channel allocation must satisfy the electromagnetic compatibility constraints known as hard constraints and the demand of channels in a cell for new calls as well as existing calls. In this paper, we propose a distributed dynamic channel allocation (DDCA) algorithm show blocking probability of distributed dynamic channel allocation is reduced by increase spectral efficiency. The proposed algorithm is based on a distributed dynamic channel allocation technique is to increase the throughput of the system for an blocking probability.
