Design of a dynamic distributed mobile computing environment

Many of the embedded systems have integrated the features of multimedia, networking, and mobility in a device. With the capability of wireless communication, mobile devices can be connected to share information, and even more, work together to accomplish a more complex job. In this paper, a novel distributed mobile computing model based on the concept of dynamic task group is proposed. Through this dynamic distributed mobile computing (Dynamic-DMC) model, computing resources can be added and removed dynamically according to the availability of the resources. An environment supporting the Dynamic-DMC model, called D2MCE, has also been implemented. In D2MCE, a shared memory abstraction layer is provided for the purpose of easy programming. An example D2MCE program is also given in this paper. The Dynamic-DMC model and the D2MCE implementation can also be used in traditional cluster computing. Initial result shows that the performance of D2MCE is acceptable.
