It is very necessary for the mobile computing system to be equipped with the checkpointing recovery facility because of the fact that the MHs are vulnerable to the failures. Previous recovery schemes based on message logging are under the condition that exchanged messages among mobile hosts are forwarded by MSSs(m-MSS-m communication). A new recovery protocol is presented for mobile host direct to mobile host(m-m) communication wireless network in this paper. The m-m communication contributes to a less contention on the wireless network and a lower latency for message transmission than m-MSS-m. Theoretical analyses and simulation results show that the proposed approach provides higher performance in terms of fail-free overhead and recovery overhead than traditional schemes.
