Abstract
This paper presents an Execution Management System (EMS) for Grid services that builds on the Open Grid Services Architecture (OGSA) while achieving “mobile awareness” by establishing a WS-Notification mechanism with mobile network session middleware. It builds heavily on the Session Initiation Protocol (SIP), used for managing sessions with mobile terminals (such as laptops and PDAs) where the services are running. Although the management of mobile services is different to that of ubiquitous services, the enhanced EMS manages both of them in a seamless fashion and incorporates all resources into one Mobile Dynamic Virtual Organization (MDVO). The described EMS has been implemented within the framework of the Akogrimo EU IST project and has been used to support mission critical application scenarios in public demonstrations, including composite and distributed applications made of both ubiquitous and mobile services within multiple domains.
