Research on Mobile MOM Supporting Data Sharing

Recently, the popularity of mobile devices increasingly demands mobile computing techniques. Due to the special particularities of mobile computing environments, users will typically modify local replicas of shared data independently during disconnection. The inconsistent data need to be reconciled when they get connected again. Message is also a kind of data that should be shared. Message oriented middleware (MOM) is a specific class of middleware that supports communication among distributed components via message passing. Existing MOM systems don´t support the real mobility and they simply replace messages of the same key, instead of reconciliation. In this paper, we analyze a scheme of conflict resolution for data sharing in mobile computing, and propose a new framework of a Mobile MOM with the support of data sharing, which is based on the conflict resolution scheme and an existing MOM system. Experimental results show the Mobile MOM system enables transparent sharing of messages across heterogeneous mobile hosts. So users can conveniently manipulate and pass messages through asynchronous communication in mobile computing environments.
