Transmission control protocol (TCP) assumes a relatively underlying network where more packet loss is due to congestion. In a wireless network packet losses will occur more often due to unreliable wireless links. When TCP is used over-wireless networks, each packet loss on the wireless link results in congestion. Congestion control mechanisms have to be applied, after finding out the reasons for packet...
In this demo, we showcase DiffQ - a congestion control protocol inspired by theoretical cross-layer optimization approaches. DiffQ can support congestion control for network flows that use either single-path or opportunistic multi-path routing. Our demo will focus on the performance in single-path routing environments, where contemporary end-point congestion control algorithms like TCP face severe...
The following topics are dealt with: quality of service and routing; CAC and resource allocation; wireless networks; security and transport protocols; transport networks; multicast protocols.
In this paper, we describe and analyze a joint scheduling, routing and congestion control mechanism for wireless networks, that asymptotically guarantees stability of the buffers and fair allocation of the network resources. The queue-lengths serve as common information to different layers of the network protocol stack. Our main contribution is to prove the asymptotic optimality of a primal-dual congestion...
