    Greater understanding of biology in modern times has enabled significant breakthroughs in improving healthcare, quality of life, and eliminating many diseases and congenital illnesses. Simultaneously there is a move towards emulating nature and copying many of the wonders uncovered in biology, resulting in "biologically inspired" systems. Significant results have been reported in a wide range of a... View full abstract»

    It is hard to build robust systems: systems that have acceptable behavior over a larger class of situations than was anticipated by their designers. The most robust systems are evolvable: they can be easily adapted to new situations with only minor modification. How can we design systems that are flexible in this way? View full abstract»

    This paper describes, and evaluates benefits of, a design methodology to translate certain mathematical models into the design of novel, self-adaptive, peer-to-peer (p2p) distributed computing algorithms ("protocols"). This methodology is potentially a good vehicle for translating natural phenomena, representable via mathematical models, into practical p2p protocols. Concretely, our first contribu...

    The concept of self-organization is rapidly gaining importance in the area of distributed computing system However, we still lack the necessary means for engineering such system in a standardized way since their common properties are rather abstract, and the mechanisms from which self-organization emerges are too diverse. Therefore,it has become common practice to engineer computing systems by tak... View full abstract»

  • A Space- and Time-Continuous Model of Self-Organizing Robot Swarms for Design Support

    Designing and implementing artificial self-organizing systems is a challenging task since they typically behave non- intuitive and only little theoretical foundations exist. Predicting a system of many components with a huge amount of interactions is beyond human skills. The currently common use of simulations for design support is not satisfying, as it is time-consuming and the results are most l... View full abstract»

    Ant algorithms and flocking algorithms are the two main programming paradigms in swarm intelligence. They are built on stochastic models, widely used in optimization problems. However, though this modeling leads to high- performance algorithms, some mechanisms, like the symmetry break in ant decision, are still not well understood at the local ant level. Moreover, there is currently no modeling ap... View full abstract»

  • Text Display and Graphics Control on a Paintable Computer

    Consider a display architecture where every pixel has its own dedicated graphics engine. Toward this end, we recast the rendering and graphics control of text for use on a paintable computer. Work on paintable computing is reviewed with a focus on the programming model based on autonomous, mobile code fragments (pfrags) which self-assemble into larger virtual structures. A device simulator is used... View full abstract»

    Studies on animal reasoning can serve as a very relevant guide in building artificial systems that autonomously evolve their cognition and develop new skills in structural/functional coupling with their environments. New Caledonian crows display sophisticated abilities in fashioning tools and using them to acquire otherwise unobtainable food rewards. We may consider this an act of creativity, duri...

    We describe a study in the application of digital evolution to the problem of cooperative information gathering. In digital evolution, self-replicating computer programs evolve to perform tasks and optimize resource usage in order to survive within a user defined computational environment. Instruction-level mutations during replication and CPU-cycle rewards for desired behavior produce natural sel... View full abstract»

  • Firefly-inspired Heartbeat Synchronization in Overlay Networks

    Heartbeat synchronization strives to have nodes in a distributed system generate periodic, local "heartbeat" events approximately at the same time. Many useful distributed protocols rely on the existence of such heartbeats for driving their cycle-based execution. Yet, solving the problem in environments where nodes are unreliable and messages are subject to delays and failures is non-trivial. We p... View full abstract»

    The study of synchronization has received much attention in a variety of applications, ranging from coordinating sensors in wireless networks to models of fireflies flashing in unison in biology. The inverse problem of desynchronization, however, has received little notice. Desynchronization is a powerful primitive: given a set of identical oscillators, applying a desynchronization primitive sprea... View full abstract»

  • Clustering Distributed Energy Resources for Large-Scale Demand Management

    Managing demand for electrical energy allows generation facilities to be run more efficiently. Current systems allow for management between large industrial consumers. There is, however, an increasing trend to decentralize energy resource management and push it to the level of individual households, or even appliances. In this work we investigate the suitability of using adaptive clustering to imp... View full abstract»

    Peer-to-peer index structures distributed and managed over the planet, commonly known as structured overlays (e.g., distributed hash tables), are posed to play the role of a fundamental building block for internet-scale distributed applications and information systems. One of the biggest impediment in realizing index distributed at intra-planetary scales is to be able to merge distinct indices tha... View full abstract»

  • An Amortized Tit-For-Tat Protocol for Exchanging Bandwidth instead of Content in P2P Networks

    Incentives for resource sharing are crucial for the proper operation of P2P networks. The principle of the incentive mechanisms in current content sharing P2P networks such as BitTorrent is to have peers exchange content of mutual interest. As a consequence, a peer can actively participate in the system only if it shares content that is of immediate interest to other peers. In this paper we propos... View full abstract»

    In this work we analyze the characteristics of service overlay networks generated by uncoordinated service providers that deploy different service replicas on overlay nodes across the Internet. Our approach differs from previous works, that generally rely on application-level routing, in that we allow nodes to autonomously re-wire the service overlay to make it capable of absorbing a heterogeneous...
