Abstract: PURPOSE: An operation method of a WPAN(Wireless Personal Area Network) device, capable of reducing the degradation of RF reliability is provided to periodically perform a hopping operation by using a channel hopping sequence. CONSTITUTION: A connection request primitive, which allows a connection request with a coordinator to a device, is generated. The connection request primitive includes first and second parameters. The first parameter determines an offset value of a channel hopping sequence. The second parameter determines the use of a default channel hopping sequence. If the value of the second parameter is greater than 1, the channel hopping sequence is requested to its own coordinator.

Abstract: PURPOSE: A method for allocating resources in a wireless network is provided to disperse a burden about a computative quantity which can focus on one node to several nodes, thereby enhancing the energy efficiency of the node. CONSTITUTION: Cluster headers are calculated according to the cluster after the cluster is formed. A node which comprises a wireless network determines whether oneself is a edge node or not. If the node is not an edge node, the node collects link information(301) with other nodes in cluster which oneself is included in. The collected ink information is transferred ot the cluster header of the node.

Abstract: PURPOSE: A time synchronization method for a multi-hop sensor network is provided to add a delay transmission temporal value to a beacon frame for reducing the collision of the beacon frame in a beacon mode, so that receiving nodes can perform exact time synchronization. CONSTITUTION: A transmission node performs CCA(Clear Channel Assessment) and backoff for preventing collision(S101). The transmission node creates a time stamp before transmission of a beacon frame and after time delay(S103). The transmission node adds a delayed temporal value and a time stamp value to the beacon frame. The transmission node transmits the beacon frame(S105). The delayed temporal value is the temporal value delayed by performance of backoff and CCA. The time stamp value comprises an interface delay value between an MAC(Media Access Control) layer and a PHY(Physical) layer and a modulation delay value in the PHY layer.

Abstract: PURPOSE: An MAC(Media Access Control) system of a multi-hop sensor network is provided to prevent transmission delay caused by relatively long inactive duration for energy saving and the convenience of scheduling. CONSTITUTION: In the higher layer of a source device, MLME-EGTSinfo.request primitive is transmitted to MLME(MAC sub Layer Management Entity)(601). The MLME transmits an EGTS information request command to a destination device(602). The destination device confirms the reception of the EGTS(Extended Guaranteed Time Slot) information request command by transmission of an ACK(Acknowledgement) frame(603). The MLME of the destination device transmits a time stamp and an EGTS parameter to the source device(604). The source device transmits an ACK frame to the destination device(605). The MLME of the source device notifies a higher layer next to itself that the EGTS information request succeeds(606).
