TCP Friendly Rate Adaptation for Multimedia Streaming in Mobile ad hoc Networks

Transport protocol for supporting multimedia streaming in mobile ad hoc networks has to cope with the rich dynamics, including mobility-induced disconnection, reconnection, and high out-of-order delivery ratios; channel errors; and network congestion. In this work, we describe the design and implementation of ADTFRC, a TCP-friendly transport protocol for ad hoc networks. ADTFRC adapts wireline TFRC protocol to ad-hoc networks with improved rate adaptation behavior, the capability of application layer framing and selective retransmissions. It detects different loss behaviors based on end-to-end measurements of multiple metrics; this allows ADTFRC to more accurately gauge the network behavior and achieve higher throughput. Our ns-2 simulations show much performance improvement over standard TFRC and TCP with explicit-link-failurenotification (ELFN) support in terms of throughput, rate adaptation behavior and application level quality while still maintaining the TCP-Friendliness property...
