Check Pointing Arrangement in Mobile Grid Computing

Abstract


This paper deals with decentralized, QoS-aware middleware for check pointing arrangement in Mobile Grid (MoG) computing systems. Check pointing is more crucial in MoG systems than in their conventional wired counterparts due to host mobility, dynamicity, less reliable wireless links, frequent disconnections and variations in mobile systems. We’ve determined the checkpoint arrangement to be NP-complete and so consider Reliability Driven (ReD) middleware, employing decentralized QoS-aware heuristics, to construct superior check pointing arrangements efficiently. With ReD, an MH (mobile host) simply sends its Check pointed data to one selected neighboring MH, and also serves as a stable point of storage for check pointed data received from a single approved neighboring MH. ReD works to maximize the probability of check pointed data recovery during job execution.
