Paper Abstract

With the rapid development and application of Internet technology, Geographic Information System has stepped into a new age with its main form as Geographic Information Services. Although there are so many Geographic Information Services available on the Internet now, they are still in very low rate of application. To facilitate the discovery, some proposals for Geographic Information Services infrastructures focus on centralized service registry (UDDI, Universal Description, Discovery and Integration ) for cataloguing their geospatial functions and characteristics. Centralized systems introduce single points of failure, hotspots in the network and expose vulnerability to malicious attacks. In order to solve the problem above, this paper proposes A Complex Network Peer-to-Peer Approach for Geospatial Web Services Discovery. Based on complex network theory, a Peer-to-Peer network has been established, and it takes the charge of each peer's communication and management, and an EBRIM registry centre has been inserted into each peer for the registry and query of Geographic Information Services.
