Combining Source- and Localized Recovery to Achieve Reliable Multicast in Multi-Hop Ad Hoc Networks

This paper proposes a novel reliable multicast transport protocol for Multi-hop, wireless Ad hoc NETworks (or MANETs). To recover from the different types of losses that may occur in MANETs, the Reliable Adaptive Congestion-controlled Transport protocol, or ReACT, combines source-based congestion- and error control with receiver-initiated localized recovery. While the latter attempts to recover localized losses (e.g., caused by transmission errors), the former is invoked only for losses and congestion that could not be recovered locally (e.g., caused by global congestion). Loss differentiation is an important component of ReACT and uses Medium Access Control (MAC) layer information to distinguish between different types of losses.
