Resource allocation scheme to reduce communication cost in mobile ad hoc computational grids

摘要

Recent advancements in mobile computing and communication technologies have given rise to the development of mobile ad hoc computational grids which provide a software and hardware infrastructure to share computing resources in mobile ad hoc environments. The adaptation of computational grids in mobile ad hoc environments is not simple and presents numerous research challenges due to node mobility and infrastructure-less network environment. In order to improve utilisation of shared computing resources and application performance, one of the key services is a resource allocation. In this paper, we propose a centralised resource allocation scheme that allocates interdependent tasks to nodes in mobile ad hoc computational grids. First, we classify tasks and dependencies, and then exploit them to reduce communication cost between interdependent tasks, and thus application completion time. The effectiveness of proposed scheme is demonstrated through simulations.
