Abstract

In this chapter the authors study the problems of data dissemination and query routing in mobile peerto- peer networks. They provide a taxonomy and discussion of existing literature, spanning overlay topologies, query routing, and data propagation. They proceed by proposing content-driven routing and adaptive data dissemination algorithms for intelligently routing search queries in a peer-to-peer network that supports mobile users. In the authors’ mechanism, nodes build content synopses of their data and adaptively disseminate them to their most appropriate peers. Based on the content synopses, a routing mechanism is being built, to forward the queries to those peers that have a high probability of providing the desired results. The authors provide an experimental evaluation of different dissemination strategies, which shows that content-driven routing and adaptive data dissemination is highly scalable and significantly improves resource usage.

Survey Of Existing Research

We extend our discussion of existing research in the area into three different directions: Topologies for organizing the network to facilitate peer interaction, query routing mechanisms for data discovery, and mechanisms for data propagation. Table 1 summarizes our taxonomy of the relevant literature.
