Composition of Location Based Services in Decentralized Registry Based Architecture
The massive growth of wireless communications and mobile database technologies has transformed the cell phone from being a mere portable phone to becoming an essential medium for contact, information and entertainment. A new trend has been evolved in mobile services which are used to provide user location based experience. It has opened a golden door for location based services. Location-based services denote services provided to mobile users according to their geographic location. There are two registry based architecture, one is centralized and other is decentralized. In centralized architecture, first location of the user is determined and then central registry is looked up for requested services. In decentralized architecture, each of the location is supposed to be associated with a local registry which would be looked up for the requested services. But decentralized architecture is not able to give the information about services available in location other than user’s present location. There are a number of real world problems, which gives emphasis on the need of advance knowledge of availability of services present in other location and fulfillment of the total goal. Hence, in order to fulfill the above need, a methodology has been proposed in this paper. It minimizes the user involvement to a great extent in order to avail any online service. In this, composition plan would be created a priory to execution of services and selection of services would be based on QoS parameters in order to minimize the total cost.
