IEEE 802.11e Medium Access Control(MAC) proposes Enhanced Distributed Channel Access(EDCA)


mechanism to provide Quality of Service to multimedia applications. EDCA gives differentiated treatment


to high priority traffic . Despite this, due to the distributed nature of EDCA , network performance


degrades when additional real-time flows are injected into the network. Towards this , our work


proposes a routing mechanism that can take advantage of the service differentiation offered by EDCA


MAC and at the same time overcome its limitation under heavy load conditions thereby facilitating


transport of real-time data. Our work measures the available bandwith of the high priority access


categories, energy level and contention level experienced at the intermediate nodes to determine robust


paths and divert the audio-video stream along such less congested paths , to ensure better end-to-


end delay and throughput. Simulation studies show that our protocol is able to protect delay constrained


traffic under heavy traffic conditions.
