TCP-Friendly Congestion Control over Wireless Networks (original) (raw)

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.
