Patent abstract
Method and apparatus for varying the times and channels of broadcast beacons. The method and apparatus make it more difficult to monitor and/or disrupt such beacon transmissions. In one embodiment, pseudo-random times and pseudo-random channels are selected for transmitting the beacon messages. Preferably these times and channels are included in a beacon schedule which is transmitted with the beacon messages. In select embodiments, the beacon messages include schedules for both the transmitting node and other nodes, so that all of the nodes in the network may quickly learn the beacon schedules of the other nodes.
