23-Oct-2001 09:21 - Amsterdam - Martin Kendrick - Martin explained that the intention in this workshop is to look at the way mobile computing is being done from an applied rather than theoretical viewpoint. Growth in mobile computing has been explosive, even with the economic constraints the industry currently is having to handle. Product and technology focus has been primarily on wireless application protocol (WAP)-enabled devices, portable digital assistants (PDAs), Laptops and smart messaging system (SMS). Martin believes that most of the potential for future market growth lies in corporate use, and should not necessarily be Web-based. Real-time applications are increasingly becoming available, and this offers a very wide market for high-value business applications. As support for this approach, Martin showed part of a video from Civista that illustrates the current market demand for on-site up-to-date business information - examples are in farming, in process plants for utilities, in marketing and sales, in banking - their applications can touch every area of work. If applications in these and similar business areas are provided, then the number of mobile computing devices in use for serious business purposes is forecast to increase to 1.2 billion in 2 years. Martin's key message here is that the

23-Oct-2001 11:49 - Amsterdam - Chern Nam Yap - Chern first presented an overview of the two Wireless Internet Protocols (WIP) that are available commercially today - circuit switching (CSWIP) and packet switching (PSWIP). He considered that switching convergence from CSWIP to PSWIP is a necessity to make good use of the limited wireless bandwidth available. Continuous connection over different technologies is not possible. PSWIP may devolve to proxy model security (PMS) and end-to-end model security (EMS). Further discussion (summarized in slides) reviewed the model convergence opportunities and problems that PMS and EMS solutions offer. Chern then reviewed IIP (Itinerant IP), which is based on EMS and supports PMS. He has an IIP draft paper currently in the IETF - see http://search.ietf.org/internet-drafts/draft-cnyap-iip-03.txt. If the correspondent node is mobile-aware, it will first query of a mobile nodes's latest address before sending any packet. Otherwise if the mobile node initiates the communication it will send the packet normally and all packets route from the first contact point. Other issues that arise include mobility (support for ad hoc mode), Quality of Service (support for protocols), and Application (support for services). Chern concluded that EMS is not perfect - one major demand it makes is that the end system has to be powerful enough to do all the processing required.
