Research On Load Balancing Technology For WEB Service Mobile Host

The position of mobile devices increases dramatically in people's life.The development of wireless networks makes the Web services provided on mobile hosts widely recognized.However,the limited resources of mobile devices lead to poor performance of some Web services hosted on mobile devices or the service requests cannot be executed at all.In order to ensure the normal operation of mobile Web services,load balancing technology in Web service mobile host devices is introduced in this paper and service requests are distributed to different mobile devices to enhance the execution ability of mobile devices.This paper researches the load balancing technology for Web service mobile hosts deeply based on the analysis and summary of mobile hosts,Web services,load balancing and program partitioning.Firstly,a load balancing framework for Web service mobile hosts is designed.The framework realizes the whole process of load balancing for mobile hosts,and achieves the purpose of making rational use of mobile device resources and improving the execution efficiency of Web services.A Web service mobile host load balancing algorithm is proposed and applied to the Web service mobile host load balancing framework.In order to realize load balancing,the algorithm will divide composite service which consume large number of resources many times into sub-services and distribute them to perform parallel in different auxiliary mobile hosts,that is,it will turn service request which can't be executed in single host into requests which can be executed in multi hosts.This algorithm improves the execution ability of the auxiliary mobile host group and shortens the response time of the user requests.Then,the load balancing framework and load balancing algorithm for Web service mobile hosts are implemented.The Web service mobile host load balancing algorithm proposed in this paper is compared with some related researches,and the advantages and disadvantages of various load balancing algorithms are summarized.Finally,a life assistant application case is given to verify the effectiveness of the Web service mobile host load balancing framework and algorithm presented in this paper.
