XMIDDLE: information sharing middleware for a mobile environment

Summary form only given. The capabilities of modern mobile devices enable new classes of applications to exploit the ability to form ad-hoc workgroups and exchange data in a very dynamic fashion. They also present, however, new challenges to application developers, related with the scarcity of resources that need to be exploited efficiently. Moreover network connectivity may be interrupted instantaneously and network bandwidth remains by orders of magnitude lower than in wired networks. To address such issues, we have designed and implemented XMIDDLE, which advances mobile computing middleware approaches by choosing a more powerful underlying data structure (XML) and by supporting offline data manipulation.
