Democratic Processing: Mastering the complexity of communicating systems

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 ...

Ludo Modi Varietas: A Game-architecture inspired design approach for BCSS

The design of Behavior Change Support Systems (BCSSs) is a multiand interdisciplinary process that involves a deep understanding of the user, mediator, social contexts and ultimately the socio-technical system. This paper attempts to demonstrate the benefit in the design process of combining four abstract modes of use (Trigger, Intervention, Assessment and Participation) from gaming, the Ludens...

Energy-Efficient Streaming Using Non-volatile Memory

The disk and the DRAM in a typical mobile system consume a significant fraction (up to 30%) of the total system energy. To save on storage energy, the DRAM should be small and the disk should be spun down for long periods of time. We show that this can be achieved for predominantly streaming workloads by connecting the disk to the DRAM via a large non-volatile memory (NVM). We refer to this as ...

Context-Aware Process Networks

In industry, embedded systems for stream-based processing are often modelled and verified by using process networks, such as Kahn process networks. An advantage of Kahn networks is that they allow asynchronous operation of process components in a network. A problem in these networks, however, is that asynchronously interfering events cannot be handled properly because they are intrinsically ind...
