Abstract: The Natural Immune System NIS is a distributed system that solveschallenging search and response problems while operating under constraintsimposed by physical space and resource availability. Remarkably, NIS search andresponse times do not scale appreciably with the physical size of the animal inwhich its search is conducted. Many distributed systems are engineered to solveanalogous problems, and the NIS demonstrates how such engineered systems canachieve desirable scalability. We hypothesize that the architecture of the NIS,composed of a hierarchical decentralized detection network of lymph nodes LNfacilitates efficient search and response. A sub-modular architecture in whichLN numbers and size both scale with organism size is shown to efficientlybalance tradeoffs between local antigen detection and global antibodyproduction, leading to nearly scale-invariant detection and response. Wecharacterize the tradeoffs as balancing local and global communication and showthat similar tradeoffs exist in distributed systems like LN inspired artificialimmune system AIS applications and peer-to-peer P2P systems. Takinginspiration from the architecture of the NIS, we propose a modular RADARRobust Adaptive Decentralized search with Automated Response strategy fordistributed systems. We demonstrate how two existing distributed systems a LNinspired multi-robot control application and a P2P system can be improved by amodular RADAR strategy. Such a sub-modular architecture is shown to balance thetradeoffs between local communication within artificial LNs and P2P clustersand global communication between artificial LNs and P2P clusters, leading toefficient search and response.
