The continuously increasing diffusion of application scenarios requiring pervasive data sensing has lead to the development of novel monitoring solutions leveraging on Heterogeneous Sensor Networks (HSNs). At the moment, only little attention has been dedicated to the design of multi-purposes applications devoted to process, filter and use data from HSNs and aimed at providing composite services to the final users. Most available networks are currently managed by custom stand-alone applications, where many low level details are handled at application level. Actually, this approach presents many drawbacks in terms of system flexibility and adaptability. In such a scenario, the main goal is to decouple application logic from low level implementation details including the HW/SW platform and the programming language. Moreover, the specific units of functionality should be organized into autonomous and connectable modules operating in a distributed computing environment. This paper presents a management framework for rapid and flexible deployment of HSN-based applications based on XMPP/Jabber, a well-known XML-based open-source Instant Messaging protocol. The proposed solution aims to speed up the integration of different software modules into a network of services. The main benefits of the proposed solution include an increase of code reusability, platform independency, system scalability and modularity. The advantages of the proposed approach are demonstrated by presenting three use-cases.
