Call blocking performance of new dynamic channel assignment scheme in microcellular radio networks

In this paper, we suggest a new dynamic channel assignment scheme with two types of channel allocation strategies, and perform an analysis on the handoff probabilities of handoff and new calls. Our scheme is compared with other existing schemes in terms of three types of blocking probabilities-new call blocking probability, handover blocking probability, and network blocking probability. Simulation results show that our scheme significantly reduces those blocking probabilities over the existing schemes. Furthermore, our scheme has much smaller number of reallocations than other schemes.
