MapUme: Scalable middleware for location aware computing applications

In this paper, a scalable middleware for supporting location aware applications, MapUme is presented. Scalability feature will enable development of a broad range localisation systems from small size to a large number of localised objects. Distributed data processing supports the scalability requirement by distributing data processing load into several computing machines. The distributed data processing is implemented using service oriented architecture which fits well with the scalability requirement. This feature promotes scalability since a main server may forward requests to multiple service instances without the knowledge of the service client. The middleware offers also extensibility of its components taking advantage of component based software development approach used.
