BEACONING TECHNIQUES IN FREQUENCY HOPPING SPREAD SPECTRUM (FHSS) WIRELESS MESH NETWORKS
First Claim
1. A method of communicating in a network, comprising:
- sending, by a first node, a message to one or more neighbor nodes;
responding, by the one or more neighbor nodes, with a message to the first node, the response message comprising a beacon frequency, a beacon transmit time and information about the current hopping sequence; and
periodically programming a receiver, by the first node, to tune to the beacon frequency at the beacon transmit time and using the hopping sequence to receive information comprising at least one of routing information and timing updates for hopping channel synchronization from the one or more neighbor nodes.

Abstract
Methods include those by which nodes in a Frequency Hopping Spread Spectrum (FHSS) wireless network may be flexibly configured for beacon transmission and reception. The method may allow for any node to synchronize to any other node'"'"'s given frequency to receive one or more beacon (broadcast) packets from that node at the designated period. The method may include sending, by a first node, a message to one or more neighbor nodes and responding, by the one or more neighbor nodes, with a message to the first node, the response message including a beacon frequency, a beacon transmit time and information about the current hopping sequence. The first node periodically programs its receiver to the beacon frequency at the beacon transmit time and uses the hopping sequence to receive information including at least one of routing information and timing updates for hopping channel synchronization from the one or more neighbor nodes.
