Abstract

Limited computing resources may often cause poor performance and quality. To overcome these limitations, we introduce the idea of ad hoc systems, which may break the resource limitation and give mobile devices more potential usage. That is, several resource-limited devices may be combined as an ad hoc system to complete a complex computing task. We illustrate how the adaptive software framework, FRAME, may realize ad hoc systems by automatically distribute software to appropriate devices via the assembly process. We discuss the problem that ad hoc systems may be unstable under mobile computing environments since the participating devices may leave the ad hoc systems at their will. We also propose the reassembly process for this instability problem; i.e., assembly process will be re-invoked upon environmental changes. To further reduce the performance impact of reassembly, two approaches, partial reassembly and caching, are described. Our experimental results show that the caching improves performance by a factor of 7 ∼ 40.
