Performance Evalu tion and Modeling of Peer-to-Peer Systems over Mobile Ad hoc Networks

With the advance in mobile wireless communication technology and the increasing number of mobile users, peer-to-peer computing, in both academic research and industrial development, has recently begun to extend its scope to address problems relevant to mobile devices and wireless networks. This paper is a performance study of peer-to-peer systems over mobile ad hoc networks. We show that cross-layer approach performs better than separating the overlay from the access networks with the comparison of different settings for the peer-to-peer overlay and underlaying mobile ad hoc network. We then present a performance model which captures most facets of mobile peer-to-peer systems. We hope our results would potentially provide useful guidelines for mobile operators, value-added service providers and application developers to design and dimension mobile peer-to-peer systems.
