METHOD ON WAKE-UP SCHEDULING OF SENSOR NODES IN MULTIHOP SENSOR NETWORKS

摘要

A kind of method of the wake-up routing of sensor node in multiple reflections sensor networks is arranged to prevent the collision of a beacon frame and makes the synchronous transmission point to transmit beacon frame of node for providing reading medium by a readable computer of the plan for allowing wake-up to execute a plan by record. The beacon frame of adjacent node is received by it and scans a channel in wireless area. Beacon offset is the time difference, between a receiving station and the starting point that can communicate with node (super frame) for beacon frame. Task node determines the beacon frame of the beacon offset based on adjacent node and is received a receiving station of the beacon offset information of the adjacent node of (S208).
