In this paper, the authors propose a topology optimisation algorithm for multi-layer P2P overlays on top of pervasive computing environments based on ant algorithms for the distributed network-wide collection of information. Their goal is to construct a robust and responsive overlay with low overhead so that it suits the highly dynamic and heterogeneous characteristics of pervasive environments. Pervasive computing environments are built over highly dynamic heterogeneous networks. Moreover, diversity exists in all aspects of such environments, including computing performance, network connections, mobility, etc. In order to reduce the perceived complexity of the underlying network, P2P overlays are usually adopted by large-scale network applications for resource discovery and network management.
