Modified reliable timeout based commit protocol

Mobile Databases with palmtops, cellular phones, car computers etc. may lead to disconnection and handoff issues due to which it is necessary to have consistent commitment of transactions in case of mobility. This paper proposes the new commitment protocol, maintains the strong transactional coherency, called as Modified Reliable Timeout Based Commit Protocol (MRTBCP), that supports off-line executions and disconnection during commitment, it decreases the cost of wireless communication by reducing the message complexity. It also supports handoff in case of Mobility. This paper extends the features of UCM.
