The formal definition of real-time atomic commitment of mobile distributed real-time transactions was introduced.On the basis of the above definition,one-phase real-time atomic commitment protocol(1PRACP) suitable for mobile distributed real-time transactions was presented.According to 1PRACP,the commitment procedure of a mobile distributed real-time transaction was completed in one-phase through a one-time message exchange between participant and coordinator.Combined with overtime recovery processing protocol,1PRACP can be free of the blocking which is caused by site failure or communication link failure.The results of performance comparison and evaluation show that 1PRACP can improve the performances of mobile distributed real-time database systems.
