Application Interaction Model for Opportunistic Networking

In Opportunistic Networks, autonomous nodes discover, assess and potentially seize opportunities for communication and distributed processing whenever these emerge. In this paper, we consider prerequisites for a successful implementation of such a way of processing in networks that consist mainly of heterogeneous devices. Devices are heterogeneous in size, in abilities, in movement, and in the role they play in the application. The focus here is on the interaction at different levels and among various nodes, in view of our current scenario, where mobile nodes connect clusters of wireless sensors. The combined networks form an infrastructure-less sensor and actuation network. We propose a RESTful interaction model, which we demonstrate with an example implemen-
