Abstract:

In this paper, an efficient dynamic channel assignment scheme is suggested, which consists of two types of channel allocation strategies; ordinary channel allocation strategy and channel reallocation strategy. An analysis on the handoff probabilities of handoff and new calls is also performed, and using the analyzed handoff probability, the presented scheme is compared with other existing schemes in terms of three types of blocking probabilities – new call blocking probability, handoff call blocking probability, and network blocking probability (incomplete service probability). Simulation results show that the presented scheme significantly reduces those blocking probabilities over the existing schemes. Furthermore, the scheme has much smaller number of reallocations than other schemes.
