Um protocolo multicast de distribuição de conteúdo em redes ad hoc móveis.

Abstract

The search for new synergies between Mobile Ad Hoc Networks (MANETs) and Peer-to- Peer (P2P) networks has engaged many researchers. Some works have tried to implement P2P content distribution networks over MANETs. However, we consider that such a direct implementation of P2P networks in MANETs could not be the best choice. We propose a new content distribution protocol for MANETs: Peer-to-MANET. Peer-to-MANET takes into account the main characteristics and problems of MANETs, while keeping the basic concepts of P2P networks. Peer-to-MANET was implemented and tested in the NS-2 network simulator, and its source code is publicly available. PUMA was chosen as the Peer-to-MANET routing protocol, due to PUMA’s best performance compared to the most representative multicast routing protocols. As an additional contribution to this work, PUMA was implemented in NS-2 and its source code is publicly available too. Besides its reliability by design, extensive simulation results show that Peer-to-MANET is efficient and robust.
