In this paper, the authors propose an autonomous distributive generation algorithm of LRC (Long Range Contact) over P2P Delaunay network, and discuss on a routing method to distant location and on range query. In a P2P Delaunay network, which builds-in a Delaunay diagram as a topology using node location, a node has connections only with its neighboring nodes. This structural property has advantages for a geometric routing and range query mechanism among nodes. However, in case a P2P Delaunay network consists of a large number of nodes, its diameter increases which causes a serious communication delay in the wide area of range query. To overcome the problem, the authors show a method for nodes to construct LRC collaboratively in a bottom-up fashion both horizontally and vertically over a P2P Delaunay network to the entire target space, and provide algorithms for geometric routing as well as efficient range queries by use of horizontal/vertical LRC's. Moreover, algorithms for partial structural maintenance due to node join/leave are given. The authors examine the loads for generating/maintaining LRC, and the efficiency for routing and range query using LRC through numerical simulations. As a practical application, we set a scenario of a communication network for victims in a disaster area and rescue crues, and compare the efficiencies between the proposed system and two types of network topologies using GeoPeer numerically.
