Bio-inspired communication methodologies promise to enable more scalable self-organizing network infrastructures. Especially in the area of mobile ad hoc sensor networks, such solutions are required in order to qualify them for simplified development and deployment based on autonomously evolving mechanisms to work on global tasks, i.e. to show an emergent behavior. In this paper, we introduce t...

We propose Mixcoin, a protocol to facilitate anonymous payments in Bitcoin and similar cryptocurrencies. We build on the emergent phenomenon of currency mixes, adding an accountability mechanism to expose theft. We demonstrate that incentives of mixes and clients can be aligned to ensure that rational mixes will not steal. Our scheme is efficient and fully compatible with Bitcoin. Against a pas...

Today’s organizational renewal and change is conducted primarily within projects (i.e., temporary organizations), and, in varying degrees, includes information and communication technology (ICT) systems that should mediate or trigger intended changes. However, the definite duration of a project process and the indefinite duration of ICT-mediated change processes cause challenges for the permane...

Emergent Computing (EC) has become a widespread concept in computer science, particularly in AI und A-Life. In this paper, the relation of EC to the philosophy of emergentism, as developed by Alexander, Broad, Morgan and used in modern theories of self-organisation, is discussed using examples from the theory of cellular automata. Additionally, fundamental issues of emergentism and (in-)determi...

With the advent of virtualization technology and its propagation to the infrastructure of Cloud distributed systems, there is an emergent request for more effective means of communication between virtual machines (VMs) lying on distributed memory than traditional message based communication means. This paper presents a distributed virtual shared memory mechanism called ZIVM (Zero-copy Inter-VM)...

We present a model consisting of a swarm of unmanned, autonomous flying munitions to conduct a synchronized multi-point attack on a target. The Unpiloted Air Vehicles (UAVs) lack global communication or extensive battlefield intelligence, instead, relying on passive short-range sensors and simple, inter-agent communication. The multi-point synchronized attack is successfully demonstrated in a s...

The rapid exploitation of communication networks in progressively more aspects and their associated complexity have critically driven the desire for autonomic self-organized capabilities to provide scalable adaptive, resilient and emergent behaviour to maintain their operational capability in dynamic situations. The principles of achieving autonomic capabilities are inspired from biological and...

This paper presents the reflective perspectives of the student and supervisor in a successful computer-mediated research relationship. Key contributing factors are discussed in a dialogue format covering the role of computermediated communication (CMC), the projection of social presence, student self-efficacy beliefs, the role of information and communication technology (ICT), and interaction i...

obviously, each emerging scientific field is confronted with the challenge of distinctive explanation in terms of theoretical-conceptual framework. entrepreneurship, which is not an exception to this rule, is also to go through this challenge to prove its scientific distinction as an essential requirement. the definition of entrepreneurship will help to provide a basis for conduct of entreprene...
