Hierarchy Content Organization and Delivery for Mobile Engineering Computing

In this paper, we propose a novel architecture to enable engineering content exchange in mobile computing environment by using a language which is extended from eXtensible Markup Language (XML). To solve the challenges that we are facing in mobile computing environment where network resource and computational resource are limited, we use a hierarchy content representation and on-demand progressive transmission mechanism for an engineering field service automation application, which features with rich graphical engineering content including drawing, schematics, plans, circuits, maps, etc. Since content is delivered and represented in a progressive fashion based on user request, both problems of limited network resource and computing resource are being minimized.
