Coexistence Issues in Contention-Based Heterogeneous Wireless Networks


This paper deals with coexistence issues among contention-based heterogeneous wireless networks that have different transmission power and/or coverage. We show that the existing carrier sensing multiple access mechanism, which is a prevailing contention-based protocol, results in a significant unfairness of channel sharing. We analyze the reasons of such unfairness by considering the mutual effects of inter-system interference, carrier sensing, contention resolution, and link adaptation mechanisms. Via simulation study, we evaluate and compare the performance of several approaches for fair channel sharing.
