Design and implementation of a TCP-friendly transport protocol for ad hoc wireless networks

Transport protocol design for mobile ad hoc networks is challenging because of unique issues, including mobility-induced disconnection, reconnection, and high out-of-order delivery ratios; channel errors; and network congestion. We describe the design and implementation of a TCP-friendly transport protocol for ad hoc networks. Our key design novelty is to perform multi-metric joint identification for packet and connection behaviors based on end-to-end measurements. Our testbed measurements and ns-2 simulations show a significant performance improvement over standard TCP in ad hoc networks.
