Self adaptive web services in heterogeneous ubiquitous environment

Abstract

The development in the field of mobile application is booming tremendously because of the extensive use of smart phones. Mobile app has become a very familiar term in the world today. The current app market is forcing vendors to release richer and richer apps today. The fascinating role of Web Service in app development is a response method that allows app to remotely access or modify data by means of transferring machine readable file formats such as XML and JSON for updating display. Object Oriented Programming (OOP) concept is used to build and analyse user interfaces in app development while invoking web services for the mobile clients. The basic of OOP approach is more verbose and error prone, leading to decoration of the objects with methods during both development and maintenance. However the concept of aspects decorates objects. It is possible if the functional language treats functions as first-class objects. The need for Aspect Oriented Programming (AOP) in an implementation of mobile app illustrates a development attitude for the separation of crosscutting concerns. The distinguishing characteristic of Aspect Oriented Programming (AOP) is the ability to change its behaviour of code invisibly, by adding external hooks (pointcuts) that run code (advices). OOP, the regular method is forced up in the hierarchy tree and AOP independently identifies the aspects and uses AOP to handle the exact composition to a sole executable program. The predefined methods used in OOP cannot be used anywhere when a prospective client wants to develop his unique idea into an application. In this research work, flexibility an Aspect from AOP is going to be applied to the user interface classes of various iv mobile applications in assorted atmospheres. The aspect adds the additional behaviour to the user interface and makes it flexible since it is invoking a REST web services when required. The user interface classes can be modified from the Bezier path curves when they are applied to the classes with the help of OOP. The
