QoS-Aware Fair Scheduling in Wireless Ad Hoc Networks with Link Errors

To provide scheduling in wireless ad hoc networks, that is both highly efficient and fair in resource allocation, is not a trivial task because of the unique problems in wireless networks such as location dependent and bursty errors in wireless link. A packet flow in such a network may be unsuccessful if it experiences errors. This may lead to situations in which a flow receives significantly less service than it is supposed to, while other receives more, making it difficult to provide fairness. In this paper we propose a QoS-aware fair scheduling mechanism in ad hoc networks considering guaranteed and besteffort flows in the presence of link errors. The proposed mechanism provides short-term fairness for error free sessions and long-term fairness for the erroneous sessions and allows a lagging flow to receive extra service and a leading flow to give up its extra service in a graceful way. It also maximizes the resource utilization by allowing spatial reuse of resource. We also propose...
