Abstract

For supporting mission-critical applications in a mobile network system, hybrid checkpointing has been proposed. In a recent mobile network, wireless LAN protocols such as IEEE 802.11 and HIPERLAN are getting popular and communication with mobile computers is realized by using Mobile IP in the Internet. This paper proposes a novel hybrid checkpoint protocol. Here, message logging for mobile computers is achieved based on the broadcast property of wireless LAN protocols. In addition, by extending Mobile IP, network overload in recovery is avoided. For both checkpointing and recovery in the proposed protocol, all required information is piggied back to messages. That is, no additional message is required.
