Abstract: In this paper, we first identify some problems occurring in case traditional causal message logging approach for distributed systems is used as a fault-tolerance technique for mobile nodes in Mobile IP based systems. Then, we present a new causal message logging protocol with independent checkpointing efficiently handling several constraints of mobile nodes such as mobility and disconnection, limited life of battery power, small amount of storage and low bandwidth on wireless link. Moreover, the protocol can considerably reduce the number of additional messages and forced checkpoints needed when garbage collecting the log information of mobile nodes compared with previous causal message logging protocols.
