Because of the limited capability of mobile devices and lower bandwidth of wireless network, Web-based e-commerce in mobile wireless environments suffers more challenges and it needs an efficient and reliable mechanism to support the process. This paper presents a flexible and configurable mechanism, which uses mobile agents as brokers of mobile device to communicate with Web server, thus to reduce the unnecessary wireless communication costs of mobile client. It can also facilitate mobile device recovery back when suffering a failure to increase the reliability of the whole application process. Compared with other mechanisms through performance analysis, our mechanism shows its efficiency and reliability.
