IMPLEMENTATION OF EVENT BASED PROGRAMMING ON LOCATION AWARE MOBILE APPLICATIONS

Mannam Chandra Sekhar and Mudiganti Vijaya Bhaskar

The programming paradigms and middleware architectures are designed to support the development of mobile applications as they are became more widespread and increasingly very essential. For the development of mobile applications, the event-based programming paradigm is a strong candidate as it gives congenital platform for the loose coupling between components required by mobile applications. Although existing middleware supports the event-based programming paradigm, it is not well accepted to give support for location-aware mobile applications in which intensely mobile components come together dynamically to collaborate at some location. In this paper we present a number of approaches which involves location-independent announcement and subscription coupled with location dependent filtering and event delivery which can be used by event-based middleware. This paper discusses how these approaches have been put into action in STEAM which is an event-based middleware and it is a fully decentralized architecture that is clearly suits to deploy in ad hoc network environments.
