Mobile Hand Map Service Based On Mobile Agent Technology

Nowadays,mobile phone becomes an indispensable tool for communication and entertainment,and plays a very important part in people抯life.With the coming age of 3G time,more and more service and applications come out,one of which is hand map service.Hand map service is a new service but has a wide market foreground and significant meanings.Using of GPS technology to achieve high quality orientation, mobile phone communicates with hand map server through wireless network,by the way of client mode or WAP.This framework enables mobile phone users to inquire about location information of themselves and others,to acquire circumjacent information,to find out the road map for driving navigation,to get the geographical information that interested.Demanded result are displayed to users through man machine interface in forms of letters,maps and motion pictures.Mobile agent is a simple,flexible and extensible technology,it provides a bran-new but feasible software design model for hand map service.Based on Mobile Agent technology, burdensome computing task could be transferred to high-performance severs,thus scarce wireless network is saved by reducing data transmission,then hand map service can supply applications with better quality,faster speed and higher security.This will farther advance people抯efficiency in work and traffic,at the same time this may create value. And for the feature of moving computing and beyond platform,mobile agent technology makes system maintenance and extended function on network become easy,this does good for the expandness and popularization of the service.This article firstly expatiates the system framework of actual hand map service, mainly describes the key technology——hand map explorer,including its definition,intention,function module and supported applications.We also study on the A-GPS technology,and get its advantages through comparison with stand alone GPS.And then discusses on the concept,advantages,system framework,typical applications and developing direction of mobile agent technology. Based on the research,the article give a new model for the service——MAHMS(Mobile Agent based Hand Map System).We choose Kaariboga as the prototype to design the mobile agent system,gene theory is imported to optimize the system.We separate individuation information from common function module,use gene theory to depict mobile agent抯 basic character,use XML to store individuation information.This method predigests the structure of mobile agent,and greatly enhances its applicability.Finally,we do a research which is one of the projects of my company,we summarize the article and design emulational experiment to validate and analyze the feasibility and advantage of the model.We design the applications on mobile phone and bring forth the software,it could achieve functions such as map scanning,orientation,information searching and Travel navigation,and so on.
