An adaptive P2P overlay for MANETs

Abstract

In recent years, many researchers have focused on the deployment of Peer-To-Peer (or P2P) applications over Mobile-Adhoc NETworks (or MANETs) motivated by the common characteristics shared between the P2P overlay and the MANET underlay such as decentralization, self-organization and dynamic topology. However, conventional P2P overlays which consist on virtual connections between peers are usually constructed without considering the physical underlay. This causes a considerable mismatch between the P2P overlay and the network underlay and leads to unnecessary network traffic and inefficient paths between overlay neighbors. In this paper, we propose an adaptive overlay over MANET. The objective of our proposal is to build an unstructured overlay with the consideration of the MANET underlay topology. Simulation results show that our overlay likely-matches and fits the MANET underlay.
