The Reliability Multihop Routes with Autonomous Cooperation

Barrage relays networks (BRNs) are mobile ad hoc networks based on an autonomous cooperative communication scheme that eliminates the need for link-based coordination between nodes (e.g., collision avoidance and routing). BRNs are therefore based on a physical layer resource that is not a single link, but a region of cooperative, multi-hop transport fabric. Simultaneous unicast flows in BRNs can be supported by spatially isolated controlled barrage regions (CBRs) which may be analyzed as multi-hop routes with autonomous cooperation. This paper compares the reliability of multihop unicast transmission via CBRs to that of traditional link-based routes. The analysis of a linear network model for CBRs is used to illuminate the substantial improvements in multihop transmission reliability afforded by the barrage relay mechanism. Specifically, the above analysis demonstrates significant benefits as compared to traditional routes, multi-hop routes with ideal, instantaneous rerouting, and multipath routes comprised of independent paths.
