Abstract Service Oriented Grid Computing is an emerging technology which raises challenging issues in the area of distributed computing. Grid can be defined as an infrastructure that couples computers, devices, catalogued data and databases to offer dependable and pervasive access to resources. Service Oriented Grid extends this idea and defines Grids as collection of services, thus forming a Service to Service environment (S2S). Service Object Oriented Computing Environment (SORCER) based on evolution of the concepts and lessons learned in the FIPER project provides a federation of consistent services. SORCER defines service as any abstract concept representing a computation or an application or a hardware device (like a PC, laptop or a Mobile device). SORCER promises to change the way we tackle complex problems by providing a pure S2S environment. Mobile computing is another distinct paradigm of traditional distributed systems, considering mobility, portability and wireless communications. The recent advances in wireless communication technologies and portable mobile appliances make more number of people be eligible to access information services through a shared network infrastructure with their own mobile computing devices, regardless of their physical location. The current S2S environment do not take into account the mobile computing environment since mobile devices have not been seriously considered as valid computing resources or interfaces in S2S communities. Mobile devices have two possible roles in S2S environment. First, mobile devices can be used as interfaces to the Grid. Thus, a mobile device can initiate the use of Grid resources, monitor the jobs being executed remotely, and take any results from the Grid. Secondly and more interestingly, mobile devices can themselves participate in a Grid as computing resource providers, not just service recipients. We believe that recent advancement of technologies on mobile devices and wireless communications make this scenario more feasible. One can envision a world in which a wireless, mobile user with one or more portable devices interacting with service Grids. My research is based on these Mobile devices which have limited memory, limited CPU processing power and intermittent connectivity and their interaction with service Grids. I would address the following issues required to design the appropriate framework for the Mobile devices based on Connected Limited Device Configuration (CLDC) to be integrated with SORCER • Gateways that mobile devices use to access grid services • Surrogate hosts acting on behalf of mobile devices
