METHOD AND APPARATUS FOR BATTERY LIFE EXTENSION FOR NODES WITHIN BEACONING NETWORKS |
摘要 |
<p>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</p> |
