Congestion-Aware Ad Hoc Overlay Network

RAON is a P2P system for MANET that performs query-forwarding decision taking into account link instability and power constraints. File download traffic causes significant drop in its query forwarding performance. We propose two modifications to RAON, called CAON, to reduce the effect of congestion on the query forwarding performance caused by the download traffic: (1) local feedback mechanism; and (2) download site selection algorithm to avoid overlapping download and unstable query traffic paths. Our simulation results show that CAON improves the success rate and delay of query search on RAON with low overhead.
