Flocks, herds and schools - the roles of individuals in distributed sensor systems

点击翻译按钮获取中文摘要

Highly distributed 'swarm' systems have the attraction to engineers that the whole exceeds the sum of the parts, that is, that the collective behaviour of the swarm is more complex and useful than that of each member of the swarm. Studies have shown that simple rules followed by the individual lead to the complex 'societies' demonstrated in the natural world by, for example, ants and termites. In addition to spatial distribution, such approaches provide robustness, redundancy, and in particular parallel information processing. In the engineering context, mass production of electronic and opto-electronic devices has made systems comprising hundreds or thousands of individual elements both technically and economically feasible. This project builds on the extensive experience of York University's Vision Sensor Research (VISOR) Laboratory in distributed systems, in particular the acquisition and integrated processing of image information. Examples include space-based meta-arrays of sensors and the current work on electronic compound eyes and other distributed sensor systems.
