TCP Unfairness in Ad Hoc Wireless Networks and a Neighborhood RED Solution
Overview Significant TCP unfairness in ad hoc wireless networks has been reported during the past several years. This unfairness results from the nature of the shared wireless medium and location dependency. If a node is viewed and its interfering nodes to form a "Neighborhood", the aggregate of local queues at these nodes represents the distributed queue for this neighborhood. However, this queue is not a FIFO queue. Flows sharing the queue have different, dynamically changing priorities determined by the topology and traffic patterns. Thus, they get different feedback in terms of packet loss rate and packet delay when congestion occurs. This paper shows that the RED scheme does not work when running on individual queues in wireless nodes.
