An adaptive transmission mechanism for parallel applications in wireless environments

Research output: Contribution to journalArticle

Abstract

Parallel computing is a common technique for reducing execution time in distributed systems. An application is divided into several subtasks that can be executed simultaneously on a set of computers. Numerous parallel computing protocols and experiments have been measured on wired network environments, but little attention has been devoted to wireless networks. Wireless environments own characteristics that are unusual in wired networks, such as limited bandwidth, frequent disconnection, low power, and mobility. Due to the unique characteristics, the performance of parallel computing in wireless networks is degraded. This paper implements an adaptive transmission mechanism to cope with network contention and frequent disconnection. Experimental results show that the mechanism reduced total execution time effectively.
