SUMMARY Wearable, handheld, and embedded or standalone intelligent devices are becoming quite common and can support a diverse range of applications. In order to simplify development of applications which can adapt to a variety of mobile devices, we propose an adaptation framework which includes three techniques: follow-me, context-aware adaptation, and(More)
Certificates play a critical role in mobile applications. By exploiting certificates, mobile applications are capable of accessing the trading or other m-commerce services (mobile commerce) on mobile environments. WTLS (Wireless Transport Layer Security) [1], WPKI (Wireless Public-Key Infrastructure) [3], WIM (Wireless Identity Module) [5], and WMLScript(More)
In this paper we design the heterogeneous network instead of homogeneous one to reduce the load of single node and as a result it could eliminate probability of wireless sensor network (WSN) overload. For wide feasibility in China northwestern area we choose the Global System for Mobile Communications (GSM) to transmit monitoring data to server and(More)
To accomplish developing mobile web applications on variety of mobile execution environments, we propose Pervasive User interface Markup Language (PUML) describing user interfaces for applications on the small devices , and Pervasive loGic Markup Language (PGML) representing the computational logic of the applications. Furthermore, we exploit the XSLT/XPath(More)
