Computational grid usually plays an important role in mobile-computing application. As well known, mobile device has some inherent characteristics, such as limited energy, intermittent connection, and versatile bandwidth. Mobile computational grid need to take these issues into account. Existing task scheduling algorithm proposed for wired networks did not consider these issues mentioned above, then it did not provide stable and fast execution mobile-computing application. In the paper, we propose a Resource-Aware Task Scheduling algorithm, named RATS, on the mobile computational grid environment for mobile clients executing mobile-computing application. Based on RATS, mobile clients find suitable order of task and choose stable and fast mobile grid node to execute mobile-computing application; mobile clients choose stable mobile gird node to avoid time of fault execution; mobile clients avoid to successively use specific mobile grid node that consumes energy seriously, then entire mobile grid node improve survival rate.
