Enhanced Multipath Routing With Congestion Avoidance for 802.11e Based Mobile Adhoc Networks
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, the authors' 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.
