Handling disconnection in mobile database transaction

摘要

In this paper, our concern is the management of disconnection in mobile transaction that access temporal database and/or spatial database. We improve and extend the Mobile-shadow (M-Shadow) technique which handle disconnection in mobile transaction that access temporal database. M-Shadow uses a notation of actionability, which differentiates the actions to be taken during the transaction's validation phase according to the types of affected attributes. The M-Shadow technique increases the success probability of transactions processed under optimistic concurrency techniques.
