摘要：Mobile system typically uses wireless communication which is based on electromagnetic waves and utilizes a shared broadcast medium. This has made possible creating a mobile distributed computing environment and has brought us several new challenges in distributed protocol design. So many issues such as range of transmission, limited power supply due to battery capacity and mobility of processes. These new issue makes traditional recovery algorithm unsuitable. In this paper, we propose hierarchical non blocking coordinated checkpointing algorithms suitable for mobile distributed computing. The algorithm is non-blocking, requires minimum message logging, has minimum stable storage requirement and produce a consistent set of checkpoints. This algorithm requires minimum number of processes to take checkpoint.
