Effective Superpeer Control Messages for P2P Virtual Network in MANET

摘要

Peer to Peer (P2P) utilizes the resources of an offered service without the need for a central server or preexistent server-client, making it a desirable network environment for data exchange based on direct connection between peers. Proposed by Sun Microsystems, JXTA is a typical P2P system and distributed computing model that does not require central service resources and is flexible to deal with various network configuration changes. Meanwhile, Mobile Ad-hoc NETwork (MANET) is a typical wireless network configured with mobile nodes and without an infrastructure, where a network is established by direct connection or through other peers in the propagation area. Thus, MANET maintains the latest path information by establishing paths and changing path information for communication between peers in a highly mobile wireless network. Accordingly, this article proposes the JXTAMANET method for wireless networks to enable JXTA to be applied to MANET. NS2 is used to evaluate the performance, and the proposed architecture is shown to produce better results than a conventional flooding method.
