Within the Agent Service Subsystem exist the Agent Management subsystem and User Man-agement subsystem, which provide the overall functionality of the parent subsystem. The Agent Management subsystem manages the creation of agents and provides search results to users. The User Management subsystem manages the creation of users (at the arrival of hotel guests) and maintains a user database.
YP Server
The YP Server provides a list of online restaurant servers where the Mobile Agent can be dispatched. It consists of a database that provides the route list.
Restaurant Server
The Restaurant Server is normally provided by each participating restaurant to host the Mobile Agents. The server provides all the information related to the search request submitted by the customer. The dispatched Mobile Agent from the
ASC will roam the Restaurant Servers according to the order as inscribed on the route list.

View Status of Search
The user selects an agent from a list of mobile agents using the system Web page. Upon select-ing an agent, the user views the search status of VHOHFWHGDJHQWE\LQYRNLQJWKH³YLHZVHDUFK´ option. The agent controller coordinates the get search status event by asking the static agent to get the search results from the restaurant search results database, which resides in the ASC server. The results will then be displayed on the user screen.
Based on these inputs from the user, the mobile agent will roam from one server to another (each server being hosted by a restaurant and providing information about the restaurant) looking for res-taurants that match the user’s requirement. After the results are consolidated, they will be displayed on the user’s PC. If the number of results obtained from the search is large—for example, more than 20—the system will then inform the user that the search has led to many results and will give him or her the option of either seeing all of them or UHGH¿QLQJWKHVHDUFKFULWHULD

Summary of System Features
A mobile agent system has been developed to perform a restaurant food search for customers from restaurants with a Web presence. Also, GHWDLOVRQSURPRWLRQDORIIHUVDUHDOVR³SXVKHG´ to the user. While not described in this chapter, the security of the system and integrity of the data are ensured by means of cryptography and digital signature schemes. The system provides a user-friendly environment for easy usage.

FUTURE ENHANCEMENTS
%HVLGHV¿QHWXQLQJWKHV\VWHPWRUXQLQERWK Aglets and HP Web Services environments, we are also working on the following areas: We are extending the ASC functions to handle reservation requests from the user. This will require further mobile agent activity such that the mobile agent will interact with the restaurant reservation system to place a booking. This will naturally involve payment options that must be provided for the user to pay for his meals. To push the technology
CONCLUSION
The above sections and application example have demonstrated the feasibility of creating a bridge to link Aglet and HP Web Services into a virtually common platform for recreating mobile agent ap-plications. Such a mobile agent-based e-commerce system can indeed offer competitive advantages WREXVLQHVVHVDQGKHOSPDQDJHLQIRUPDWLRQÀRZV to strategically link enterprises. Main advantages achieved through such a system are:
further, we also are exploring the possibility of allowing autonomous negotiation by the mobile agent. Basically, mobile agents representing the users and the restaurant servers will meet at some cyberspace negotiation room to transact their requests for the respective hosts they are representing (Quah & Goh, 2002).
1. Lower cost of operation. This is mainly achieved through autonomous processes of the mobile agents.
(I¿FLHQWVXSSO\FKDLQPDQDJHPHQW,QWKH application example, hotels and restaurants have achieved a win-win collaboration through linking their services into a seam-less system that provides added value for their common customers—hotel guests.
