| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 90 === Parallel computing is a common technique to reduce execution time in distributed systems. An application is divided into several subtasks that can be executed on a set of computers. Numerous protocols and experiments have been measured on wired network environments. However, little attention was devoted to wireless networks. There exist characteristics that are unusual in wired environments, such as limited bandwidth, frequent disconnection,low power, and mobility. Due to the unique attributes, the evaluation for distributed applications on wireless environment becomes necessary. This thesis demonstrates the performance measurements for distributed applications in the wireless environment. It compares two transmitting mechanisms and simulates the disconnection that is frequent occurred in the wireless network. The results show that avoiding network contention and dispatching subtasks dynamically improve the system performance.
