With LBS, mobile device (client) needs to commit user's location information as a request to the remote server (server). The server receives the...
Recently, Qin et al. proposed a three-tier Peer-to-Peer (P2P) architecture for real-time file search in distributed networks [8]. In this architecture, indices of files held by the user peers in the bottom layer are stored at the super-peers in the middle layer, and the correlation of those two bottom layers is controlled by the central server(s) in the top layer using the notion of tags. In Qin's...
In this paper, we propose a hierarchical architecture to realize a real-time file search in P2P systems. The proposed architecture consists of three layers. Index of files held by the peers in the bottom layer is stored at the peers in the middle layer, and the correlation of peers in the two bottom layers is controlled by the peers in the top layer using the notion of tags. With such notion of tags,...
