The design of a P2P application routing protocol for heterogeneous networks

One of the key operations for P2P systems is to locate the requested resources. The efficiency of the operation depends heavily on application routing. Although many P2P systems had been proposed, they are not well suited for heterogeneous networks which consist of both wired and wireless networks. In this paper, we propose a new application routing protocol called DRIP (double-layered ring-based routing protocol). In DRIP, boundary nodes are employed to construct the P2P network. As shown in the experimental results, DRIP has proved it scalable and has low traffic overhead and latency.
