ABSTRACT	In this paper, we present a new lock management scheme which allows a read unlock for an item to be executed at any copy site of that item; the site may be different from the copy site on which the read lock is set. The scheme utilizes the replicated copies of data items to reduce the message costs incurred by the mobility of the transaction host. We demonstrate this idea in an optimistic locking algorithm called O2PLMT (Optimistic Two Phase Locking for Mobile Transactions) . Like its counterpart algorithm O2PL (Op- timistic Two Phase Locking), O2PL-MT grants read locks immediately on demand and defers write locks until the commitment time. However, O2PL-MT requires the transmission of fewer messages than O2PL in a mobile environment in which data items are replicated. 1 Introduction Following the concepts and terms introduced in [5, 3, 2], a mobile computing environment consists of two distinct sets of entities: mobile hosts and fixed hosts. Some of the fixed hosts, called Mobile...	user correction - Legacy Corrections
