Abstract
Accessing XML Web Services from mobile clients is a flexible and promising concept to build complex mobile business applications. Due to the computing constraints of mobile clients and bandwidth limitations of mobile communication systems performance considerations are essential. Usually Web Services are accessible through standard internet protocols like HTTP, but within mobile communication networks it is quite ine cient. The Wireless Application Protocol (WAP) suite provides protocols optimized for packet oriented communication over mobile links. The interconnection to existing HTTP Web Services is achieved by the use of a WAP gateway. This article presents a realization to access Web Services from J2ME mobile devices using WAP. For this, a Java Wireless Session Protocol (WSP) implementation has been developed. The performance of this WAP based access compared to HTTP is analyzed in terms of criteria as latency, data transfer volume, memory footprint and CPU power requirements.
