Handoff prioritisation with implicit channel reservation in distributed dynamic channel assignment algorithms

摘要

A new distributed dynamic channel assignment scheme with implicit channel reservation for handoff prioritisation is proposed. This scheme reduces the degree of computation and communications among base stations required for channel reservation and achieves a capacity similar to that of the maximum packing algorithm. For 40 total channels, the proposed algorithm achieves a 116% capacity increase relative to the nonprioritised fixed channel assignment (FCA) scheme and 93% relative to FCA with optimum channel reservation.
