A Structured Mesh Overlay Network for P2P Applications on Mobile Ad Hoc Networks

In this paper, we describe a Structured Mesh Overlay Network (SMON) based on a Distributed Hash Table (DHT) technique on top of a proactive routing protocol, Optimized Link State Routing (OLSR). SMON is a P2P cross-layer overlay network based on concept of CrossROAD. CrossROAD uses a pure flooding technique to form and maintain an overlay network. The broadcast mechanism has a negative effect on bandwidth usage of the network. On the other hand, we introduce a new algorithm for overlay formation and maintenance in order to reduce a number of overlay broadcast messages. The simulation results show that SMON reduces the number of overlay control overhead around 95% as compared to CrossROAD, while it maintains high query success ratio and low query delay.
