Embedded Web Server Architecture for Mobile Phone

Abstract

On dynamic embedded webserver, cgi program is adopted to complete the required workflow. Due to the resource limitation of embedded systems, the performance of embedded webserver is an important issue. To address this problem, we combine cgi with WMLscript and make them collaboratively running to satisfy the requirement of mobilephone. On embedded server, cgi processes the parameters submitted by mobilephone and appends the results to the end of wml page. On mobilephone, the WMLscript embedded in wml page will parse the results and displayed on the right place of webpage. We also designed a method that detach cgi with business logic and driver interface. In this way cgi can send parameter to driver application indirectly by exchanging parameters through linux shellt.This enables cgi and driver application to be debugged separately.
