Research On Development Technologies Of Mobile Host WEB Services And Their Application

With the popularity of mobile devices,network coverage,and the significant development of intelligent terminal technology,Web service technology in the field of mobile application is gradually expanding.As a distributed application technology,Web services can make different applications running on different machines without using third party software.REST(Representational State Transfer,declarative State Transfer)architecture concept provides a lightweight Web services technology,providing new ideas for deploying Web service in mobile device.Based on the analysis and research of related literature and technology,this paper does a deep research on mobile host Web services,RESTful Web service and load transfer algorithm for mobile host.First,mobile host Web service development technology is researched.The execution framework and process of mobile host Web services are presented.Key technologies needed in development of mobile host Web service,including mobile host Web service data storage,JSON data parsing,communication between mobile host and the client and deployment of mobile host Web service are described in detail.Then,mobile host Web service application development framework is put forward.Key technologies needed in development of mobile host Web service application are described.Socket communication technology is used to realize collaboration among the mobile hosts.Application program interfaces are used to monitor resources such as CPU,memory,and power.Heartbeat mechanism is used to send resource data of auxiliary mobile hosts.HTTP communication is used to implement communication between mobile host and the client.Then load transfer algorithm for mobile host is given and implemented.Finally,a concrete application case is presented to verify the validity of mobile host Web service and its application development technology presented in this paper.
