Abstract
There is a growing trend toward the usage of mobile computing for several applications, and it is important that the mobile systems are given adequate support at both system level and communication level. The main aim of the proposed distributed delegate object model is to reduce the round trip time (RTT) of huge number of transaction request in E-Com and M-Com applications. Delegate object is a shared object which acts as a place holder for all valuable mobile business information and updates business-related information to the customer automatically. In conventional model, all transaction requests are forwarded to the server directly, whereas in the proposed model, all the transaction requests are handled by delegate object itself which acts as a middleware component thereby reducing the RTT. The proposed model is simulated and tested in thin client and thick client test bed. The result shows improvement in RTT for both thin client and thick client environments.
