Abstract :
Recent information systems consist of mobile stations and fixed stations. Mission-critical applications are required to be executed fault-tolerantly. However, mobile stations support neither enough volume of storage, processing power nor capacity of battery to support reliable communication and computation. A hybrid checkpoint protocol for mobile computing systems is proposed. In this protocol, mobile-to-mobile communication is not supported. Thus, we propose an extended hybrid checkpoint protocol for mobile-to-mobile communication in wireless LAN protocols such as IEEE 802.11 and HIPERLAN. Compared with the conventional protocol, the proposed protocol is realized by only piggy-backing some information without additional messages
