Mobile computing systems consist of different components while Mobile Support Stations (MSSs) act a key role among others. This paper presents an efficient MSS-based non-blocking coordinated checkpointing scheme, in witch checkpointing overheads are forwarded to the MSSs and therefore workload of Mobile Hosts (MHs) would be reduced substantially. We also enhanced the proposed scheme to have much less propagating checkpoint requests and avoid avalanche effect. Simulation results show that compared to other existing algorithms, the scheme's average number of propagating requests and checkpoints are significantly lower so it would be suitable for mobile computing environment.
