document: A transactional asynchronous replication scheme for mobile database systems In mobile database systems , mobility of users has a significant impact on data replication . As a result , the various replica control protocols that exist today in traditional distributed and multidatabase environments are no longer suitable . To solve this problem , a new mobile database replication scheme , the Transaction-Level Result-Set Propagation -LRB- TLRSP -RRB- model , is put forward in this paper . The conflict detection and resolution strategy based on TLRSP is discussed in detail , and the implementation algorithm is proposed . In order to compare the performance of the TLRSP model with that of other mobile replication schemes , we have developed a detailed simulation model . Experimental results show that the TLRSP model provides an efficient support for replicated mobile database systems by reducing reprocessing overhead and maintaining database consistency
