  • Patent number: 10819437
    Abstract: A self-organizing network of nodes communicates with uncollimated optical pulses. The nodes use low-power, unmoving, broad-beam optical interfaces, low-power processors, and communication algorithms based on timeslots within a timeframe. Nodes self-organize to form the network by pulsing detectors and sources to find neighboring nodes, confirm connections, transmit and store data, and exchange partner node identities. Two- or three-dimensional networks can thereby self-organize without external awareness of network topology, and can repair themselves when nodes move or fail. Node communication may be synchronous, thereby allowing for images of the environment status, and activation of the environment is possible via node stimulators. After forming a network, a cluster of nodes may be read out to provide data from node sensors.
