The proposed multilayered WAP model uses the concept of proxy server to manage the execution of mobile transactions. To provide support for mobile transactions, a software layer, the Mobile Accessing Manager (MAM), is implemented above the preexisting multidatabase system. Performance of the system has been evaluated by varying the number of simultaneous databases using a hotel booking system. This work can be extended to global transactions in a larger context. There is a need for an extensive study on the effects of changing the distribution of data, processing I/O, caching, and communication in the near future.
