| Summary: | 碩士 === 國立東華大學 === 資訊工程學系 === 91 === As Internet use has grown to such a level on the strength of PC network. It will have an equally large impact on every organization that wants to transact business over Internet that is a new world economy platform. Mobile Internet now means more than just a new technique for communication; it is a catalyst that will revolutionize the world and innovate the way we live. Mobile Commerce is anticipated to be the next business revolution. Under the trend of mobile age, people start to realize the benefits of transactions by mobility operations. We can access information, shop and bank online, work from home, and speak and send messages via mobile appliances throughout much of the world. In this research, we concentrate on switching the existing e-commerce applications from one based on the telephone or wired Internet to one centered round mobile Internet.
Web Services are the top-notch technologies for realized the e-commerce applications. They are not just about business-to-business and they are not just about enterprise or inter-enterprise server integration. They are about making a heterogeneous collection of computers, software, and devices look more homogeneous. They will also be crucial to integrate thousands of other devices, such as cell phones, PDAs and other small business devices.
Based on Web Services technologies and mobile Internet facilities, a mobile commerce application framework was performed in our research. To investigate the feasibility of our approach, an e-store application was deployed in our laboratory. From the observations of simulation results, we found that our network performs the same conditions in different directions and mobile devices, the results we obtain should be statistically identical to those obtained by executing the same script from Address B to Address A .We suspected two possible bottlenecks: low CPU power and performance of the mobile device wireless module. We notice the bandwidth for PC and Notebook reached around 5.1Mbps more than 100% amount above of the bandwidth the Pocket Pc measured. We simulate a transaction uses HTTP with a Secure Sockets Layer (SSL) connection in multi-user situation. The response time simulation, minimum values are almost same (5users are 0.17 second, 50 users are 0.196 second), the throughput simulation, maximum values are almost same (5users are 0.365 Mbps, 50 users are 0.317 Mbps), the transaction rate simulation, maximum values are almost same too (5users are 5.882 per second, 50 users are 5.102 per second), but these three kind of experimental mean value actually has the very big difference. This also confirmed the complexity still was the main key that affects the network potency.
