【正文】 附錄 A Wireless Food Ordering System Based on Web Service Abstract—Current wireless munications enable people to easily exchange information, while web services provide looselycoupled and platformindependent ways of linking applications across the Inter or Intra. This paper presents an integration of wireless munication technologies and web services technologies to realize a wireless food ordering system. In this system, it implements wired and wireless data access to the servers and food ordering functions through both desktop PCs and mobile devices such as PDAs over a wired/wireless integrated local area work. To sure the security of the system, the secure web service architecture and some security strategies to ensure mobile munication security are discussed. Web servicesbased wireless applications on mobile devices provide a means of convenience, improving efficiency and accuracy for restaurants by saving time, reducing human errors, etc. Keywords Web Services。 Wireless。 Food Ordering System。 security I. I NTRODUCTION The rapid developments in information technology, particularly in wireless munication and web services technologies, are greatly changing the way people access and work with information. The convenience and powerful functionality offered by mobile devices such as PDAs, has encouraged many people to investigate the benefits of using them. Wireless and handheld devices abound as vendors pitch the mon themes of onetoone puting, instant munication and anytime, anywhere information access. While web services provide a technology for serviceoriented puting. Web services allow programs written in different languages on different platforms to municate with each other in a standard way . By integrating these technologies, consistent business models can be implemented on a broad array of devices: not just on mobile devices operating over mobile works, but also on servers and PCs connected to the Inter. The food ordering process in restaurants requires the coordination of simple tasks. Instruction flows mainly from customers to waiters then to kitchen and/or the bar staff, finally to the cashier . In a medium to large and busy restaurant this coordination is a challenge and requires an efficient ordering system. Errors in ordering processes lead to incorrect or out of sequence meal preparation or nonconsumable and results in added cost to the business. This paper presents an integration of wireless munication technologies and web services technologies to realize a wireless food ordering system. In this system, it implements wired and wireless data access to the servers and food ordering functions through both desktop PCs and mobile devices such as PDAs over a wired/wireless integrated local area work. The system is based on secure web service architecture and some security strategies to ensure mobile munication security are adopted. Web servicesbased wireless applications on mobile devices provide a means of convenience, improving efficiency and accuracy. II. W IRELESS LAN AND W EB SERVICES A.
