Method and apparatus for operating a node in a beacon based ad hoc network
First Claim
Patent Images
1. A method for controlling a beaconing node within communication system, the method comprising the steps of:
- associating with a network;
determining a first period of time (Δ
T) to broadcast a beacon, wherein the first period of time is based upon a time it takes for a node to associate with the network;
broadcasting the beacon for the first period of time;
ceasing beacon broadcasts for a second period of time after the first period of time has passed; and
periodically broadcasting the beacon after the second period of time has passed;
wherein the first period of time (Δ
T) is also based upon a transmission range (R) for the node and a coverage area (A) for the node.

Abstract
During operation a node (500) that has associated with a network (100) will periodically broadcast a beacon (303) during a beacon interval as part of a superframe. The beacon will be periodically broadcast for a first period of time, based on a time it takes for nodes to associate with the network. After the first period of time has passed, the beacon will be switched off for a second period of time, after which, the beacon will again be periodically broadcast.

15. An apparatus comprising:
a transmitter broadcasting a beacon for a first period of time (Δ
T), wherein the first period of time is based on a time it takes for a node to associate with the network, the transmitter ceasing broadcasting the beacon after the first period of time has passed and again broadcasting the beacon after a second period of time has passed, wherein the first period of time (Δ
T) is also based upon a transmission range (R) for the node and a coverage area (A) for the node.- View Dependent Claims (16, 17)
