Abstract
In this paper, we present a proportional fairness with bandwidth-borrowing (PFBB) scheme for a two-tier NEMO system. When traffic load is light, free-slot borrowing is employed to maximize system utilization. On the other hand, when traffic load is heavy and session arrival rates in different tiers are not proportional to their distributed areas, busy-slot borrowing is used to achieve proportional fairness. A mathematical model is built to analyze the performance in terms of the system utilization, blocking probabilities, and fairness index. Analytical results show that fairness index can be affected significantly, when session arrival rates in different tiers are varied.
