End-to-end throughput and delay assurances in multihop wireless hotspots

Next generation Wireless Local Area Networks (WLAN’s) are likely to require multihop wireless connections between mobile nodes and Internet gateways to achieve high data rates from larger distances. The paper addresses the challenges in concurrently providing end-to-end throughput and delay assurances in such mobile multihop WLAN hotspots. The proposed solution is based on the Neighborhood Proportional Delay Differentiation (NPDD) service model. Transmission Control Protocol (TCP) based applications use a dynamic class selection scheme to achieve desired throughputs. This approach integrates well with the NPDD based end-to-end delay assurance mechanisms proposed earlier. The effectiveness of the proposed solution in meeting desired throughputs is assessed with simulations. The simulation results show that the proposed solution is better in meeting the desired throughputs and delays as compared to two conventional approaches.
