Method and apparatus for battery life extension for nodes within beaconing networks
First Claim
1. A method for transmitting a beacon within a beacon network, the method comprising the steps of:
- determining if a beacon contains changed content;
determining an identical beacon counter value indicating a number of identical beacons transmitted;
inserting the identical beacon counter value into the beacon; and
transmitting the beacon to nodes within the network.

Abstract
An “identical beacons” field (401) is inserted near the beginning of a transmitted beacon (403) that contains either an integer equal to the number of consecutive identical beacons sent (i.e., identical to the one presently being transmitted) or a repetition bit indicating whether or not the beacon contains changed information when compared to a prior-sent beacon. After sleeping awhile, a node (302-304) wakes up, receives a first portion of the beacon containing the identical beacons field, and analyzes the identical beacons field. Based on the analysis, the node makes a decision on whether to remain “awake” for reception of the remaining beacon or to return to sleep.

5. A method for battery life extension for nodes within a beacon network, the method comprising the steps of:
-
receiving a beacon, wherein the beacon comprises an identical beacon field comprising a number of identical beacons transmitted;
determining a number of beacons missed since a last received beacon; and
based on the number of identical beacons transitted and the number of beacons missed since the last received beacon, either placing the node in a power conservation mode or staying awake to receive a further portion of the beacon message. - View Dependent Claims (6, 7)

8. An apparatus comprising:
-
logic circuitry determining if a beacon contains changed content and incrementing an identical beacon counter value if the beacon is to contain unchanged content;
beacon format circuitry inserting the identical beacon counter value into the beacon, wherein the identical beacon counter value indicates a number of identical beacons transmitted; and
transmission circuitry for transmitting the beacon.

9. An apparatus comprising:
-
receive circuitry for receiving a beacon, wherein the beacon comprises an identical beacon field comprising a number of identical beacons transmitted; and
logic circuitry for determining a number of beacons missed since a last received beacon, and based on the number of identical beacons transmitted and the number of beacons missed since the last received beacon, either placing a node in a power conservation mode or staying awake to receive a rest of the beacon message.
