ABSTRACT
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.
