TCP-friendly congestion control over wireless Networks

Abstract: In this paper, we present an end-to-end adaptation scheme, called the wireless loss-delay based adaptation algorithm (WLDA+). WLDA+ adapts the transmission behaviour of multimedia senders in ac-cordance with the network congestion state in wire-less environments. WLDA+ is based on the loss-delay based adaptation scheme [1] which adjusts the trans-mission behaviour of the senders in a manner simi-lar to TCP connections suffering from equal losses and delays. To take the specific characteristics of wireless links into account, WLDA+ incorporates error differ-entiation schemes to detect the loss nature in the wire-less channel. The performance of WLDA+ is then in-vestigated by simulating the behaviour of this algo-rithm under different network topologies.
