Abstract
Grid and P2P network are two major patterns in current spatial information service. However, the abilities of grid extension and P2P service are limited. A hybrid network based on region self-rule is proposed. In this hybrid network, an improved Kademlia search algorithm is employed which optimize the search routine. Furthermore, a multi-keywords fast search algorithm based on multi-keywords vector for spatial information service is proposed. Experiments validate that the proposed method improved the discover efficiency in spatial information service.
