|Title:||OCC-Mix Approach for Concurrent Mixture of Fixed and Mobile Transactions|
|Publisher:||Journal of Digital Information Management|
|Abstract:||This paper addresses a new optimistic-based concurrency control protocol, called OCC-Mix. Theproposed protocol could be used to reduce the scarswasting and expensive resources of mobile environment.This can be achieved by avoiding the unnecessary mobiletransaction restarts. Consequently, a dynamic adjustmentof serialization order in the conflicting transactions withrespect to the validating transaction will be used. As aresult, much resources of mobile environment are savedand a many fixed host transactions finished their executionwithout being affected by other mobile transactions. Theperformance of the proposed protocol was measured alongwith other related CC protocols; the simulation resultsshow that the performance of these protocols isconsistently much better than the traditional 2PL and OCCprotocols in mixed transaction environments|
