Research Of Key Technologies On Mobile Widget

In recent years, operators have launched mobile value-added business,but because of itsbusiness development platform has certain limitation, which has to to write different applicationsaccording to the different mobile terminal, to bring a lot of difficulties of the application oftransplantation, to increase the application platform development cycles and other unnecessaryspending. Therefore, whether mobile operators or mobile terminal manufacturers urgently need anew technology which can quickly adapt to the application development platform, so as to save theapplication development cost, speed up the application development speed, and can enrich the userinterface and reduce transplant cost, etc. The emergence of the mobile Widget technology caneffectively solve the problem; and the basic development platform can meet mobile operators andmobile equipment manufacturers of these requirements.Mobile Widget application development platform includes mobile Widget engine andapplication, Widget platform, Widget engine to XHTML, CSS, JavaScript technology to rely on,the mature C/S mode and reference to the advantage of B/S model developed. The key technologyof widget includes Intelligent Disk Cache, safety engineering, Interactive information technology,Change management technology, Application development technology.This paper first introduced the overall structure of and related knowledge of the mobileWidget，focusing on the Widget technologies in the cache technology, information technologyand resources interaction change management technology research, and the existing problems arealso improved.In the mobile Widget cache technology, for making up the shortage of traditional LRUreplacement algorithm,it puts forward a new replacement algorithm,which is Not only consider thecache data block size, change frequency, and the price, also considered the caching data formaintenance and the network consistent the expense required to visit the cache and the possibilityof data, and other factors, and through experiment, this replacement algorithm can improve theperformance of the Widget cach.the final experiment and test to the caching optimization Widgetengine moving validated also shows it can improve the user experience，In the mobile Widget information interaction technology, for making up the insufficiencyin,the traditional information interaction a kind of Widget information interaction model and realization mechanism which is based on intelligent terminal, based on behavior of mobile agent, isput forwarded to provide the end user of the system level API, and to make mobile agent Widgetloose coupling between the information interaction through the behavior agent.In the mobile Widget change management technology, in order to solve the problems ofapplication is not available caused by the change of resources, this paper puts forward a version ofchange management which is based on routing optimization schemes, is realized and has passedexperimental verification, and the experiments result can be effective proof to this scheme theavailability and reliability.
