Mobile wireless Ad hoc NETworks (MANETs) naturally support a traffic mix of elastic and real-time flows but the shared nature and lossy properties of the radio medium make their coexistence challenging. The authors argue in this paper for a new kind of elastic data transport service which would preserve the quality of real-time priority flows while guaranteeing an acceptaple (tunable) end-to-end delivery time of elastic data. They propose to use mechanisms from Delay Tolerant Networking (DTN) to support hop-by-hop data transfer from source to destination and an adaptation of TCP which monitors its agressiveness towards local VoIP traffic on each hop.
