Disconnected Transaction Management Scheme for Agent Based Mobile Networks

In this paper, we define a disconnected transaction management scheme for agent based mobile networks. This scheme proposes an environment in which mobile users can have simultaneous access to data by using the cache stored in the Fixed Agent. Data Access Manager module at the Fixed Agent controls the concurrency using invalidation technique. This approach supports disconnected transaction execution by allowing a disconnected mobile host to transfer transaction execution to the Data Access Manager in the fixed agent. The proposed transaction management scheme has been simulated in Java and performance of the scheme is presented.
