英文摘要	This paper presents a peer-to-peer based execution model to improve the availability and reliability of Geospatial Web Services (GWS) composition. A service community concept and a QoS model of GWS are proposed to discover the best quality GWS engines in the peer-to-peer network. The engines coordinate other participants in charge of initiating, controlling, monitoring the associated GWS execution, and adopt an alternative approach for failure recovery. The paper also presents the implementation of a peer-to-peer GWS composition system prototype based on JXTA platform.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000234791200026&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Information Systems; Computer Science, Software Engineering; Computer Science, Theory & Methods; SCI(E); CPCI-S(ISTP); 0
