A Low-cost Recovery Protocol for Mobile Computation
Mobile computing brings new challenges and requirements for checkpointing and recovery protocol.Existing recovery schemes for mobile environments typically either create global consistent checkpoints that dont guarantee independent recovery or can only support mobile-MSS-mobile (m-MSS-m) communication that exchanged messages among mobile hosts are forwarded by MSSs. This paper presents a recovery protocol based on message logging for mobile host direct to mobile host(m-m) communication wireless network. The m-m communication benefits a less contention on the wireless network and a lower latency for message transmission than m-MSS-m. Finally simulation results indicate that the performance of our approach is higher than that of traditional approaches in terms of fail-free overhead and recovery overhead.
