Using mobile agents to support unreliable database retrieval operations

One major drawback in using a client server system in the mobile environment is the redundancy of data transmission in the event of connection failure. In this paper, we present a novel mobile agent architecture which allows minimum redundancy of data transmission in a client server database connection in a frequent disconnections environment. The system supports disconnection events caused by network failure or client power failure. Unlike current approaches, our model uses agent messaging to transfer the data. The messaging reduces the amount of migrations that the mobile agents performed. The architecture was implemented and tested in the Aglets platform.
