Global Transaction Models on Mobile Computing

The issues mobile computing paradigm introduces new technical properties in the area of database systems. However, techniques for traditional distributed database management have been based on the assumption that the location of end connections among hosts in the distributed system does not change. Distributed systems are expected to support mobile computations executed over a network of fixed and mobile hosts. On the other hand, in mobile computing, these assumptions are no longer valid and mobility of hosts creates a new kind of locality that migrates as hosts move. Consequently, existing solutions for traditional distributed database management may not be applicable directly to the mobile computing environment. Many research proposals that focus on supporting transaction processing models in mobile computing environments have been developed. However, there are still major issues that have not been completely solved. One of the problems is to support the requirement for mobile transaction processing system. Here in this paper, I have presented a comparative analysis of existing mobile transaction models on the basis of reporting transactions.
