Welcome to the proceedings of the 2008 International Conference on Grid and Pervasive Computing (GPC 2008) which was held in Kunming, Yunnan, China, May 25-28, 2008. Gridcomputing presentsa newtrendindistributed computing forcoordin- ing large-scale heterogeneous resource sharing and problem solving in dynamic, multi-institutional virtual organizations. Grid computing not only can be used for distributed supercomputing massive data processing, but can also be a c- mon platform and way for utility and service computing. It covers mainframes orsupercomputersaswellasmorepowerful personal computers and even small and smart devices, ranging from personal digital assistants to unseen chips in our cars, appliances and telephones. Projecting this trend into the future, we envision an explosion of interconnected high-performance computers and smart devices that can make our research and daily lives easier and more productive. Grid and Pervasive Computing (GPC) is an annual international conference on the emerging areas of merging grid computing and pervasive computing. GPC provides a high-pro?le, leading-edge forum for researchers and engineers alike to present their latest research in the ?eld of grid computing and pervasive computing.

This book constitutes the refereed joint proceedings of seven international workshops held in conjunction with the 5th International Symposium on Parallel and Distributed Processing and Applications, ISPA 2007, held in Niagara Falls, Canada, in August 2007 (see LNCS 4742).

The 53 revised full papers presented were carefully reviewed and selected from many high quality submissions. The workshops are very specific and contribute to enlarging the spectrum of the more general topics treated in the ISPA 2007 main conference. Topics addressed are Security and Survivability in Distributed Sensor Networks (SSDSN 2007), Ubiquitous Processing for Wireless Networks (UPWN 2007), Intelligent Systems and Smart Home (WISH 2007), Semantic and Grid Computing (SGC 2007), Parallel and Distributed Multimedia Computing (ParDMCom 2007), High Performance Computing in Medicine and Biology (HiPCoMB 2007), as well as Intelligent Systems Techniques for Ad Hoc and Wireless Sensor Networks (IST-AWSN 2007).
