OnehopMANET: One-hop Structured P2P over Mobile ad hoc Networks

There are many common characteristics between P2P (Peer to Peer) overlay networks and MANET (mobile ad hoc networks). Previous work has shown that when used together, the two approaches complement each other and performance synergies can be exploited. While MANET provide wireless connectivity without depending on any pre-existing infrastructure, P2P overlays provide data storage/retrieval functionality. On the other hand, both approaches face common challenges: maintaining connectivity in dynamic and decentralized networks. This paper proposes OnehopMANET as a structured P2P over MANET the uses cross-layering with a proactive underlay. Unlike previous work, OnehopMANET uses a P2P overlay that is capable of achieving lookups in a single hop. Through simulation we show that this approach offers performance benefits when compared with approaches which employ a multi-hop P2P overlay.
