On Exploiting Location Information for Service Differentiation in IEEE 802.11 Hot Spots

In this paper, we propose a feedback framework of providing fairness and service differentiation according to location information for TCP traffic in IEEE 802.11 Hot Spots. In the framework, we introduce location access price (LAP) to denote both the network-wide and per-location channel utilization, which is delivered to TCP senders and used to adjust their sending rate. We implemented the proposed framework in ns-2 simulator, and conducted a simulation study so as to evaluate its performance. The simulation results indicate that the proposed framework can provide location-based service differentiation in IEEE 802.11 Hot Spots.
