DISTRIBUTED REACTIVE RESOURCE AND SCHEDULE MANAGEMENT IN TIME SLOTTED CHANNEL HOPPING NETWORKS

摘要

Wireless channels and timeslots are allocated in a distributed and reactive manner by network devices. A source device sends to neighbor devices a track discovery request indicating a destination and data bandwidth / channel and timeslot requirements. The neighbors conditionally forward the message until it reaches the destination device. The forwarded message includes information about the devices traversed by the message. Messages will not be forwarded if the recipient lacks sufficient resources to accommodate the data bandwidth requirements. The destination selects a path to be a communications track based upon characteristics of the one or more paths by which the request was received, and sends a reply back to the source device along the selected path. Once established, tracks may be kept alive, updated, and/or repaired via messaging among the devices along the track.
