摘要： For a sensor network having reference nodes and sensor nodes, A method and apparatus using a distance determining algorithm for a sensor network having reference nodes and sensor nodes. A distance determining algorithm is executed to determine an adequate distance between reference nodes within a preset error range, and a position location table is created. A sensor node sends a location information request to reference nodes, receives the position location table and location information from the reference nodes, and computes the coordinates of its position. Alternatively, without requesting transmission of the position location table, the sensor node may receive calculated coordinates of its position directly from a reference node.

摘要： A medium access control (MAC) frame provision method establishes security in an IEEE 802.15.4 network. A MAC frame is generated, which includes a MAC header, a payload field, and a frame check sequence (FCS) field, the payload field including relevant main data according to a frame type defined in the MAC header. A disguised decoy data sequence number (DSN) is generated and inserted into the MAC header. A real DSN, which is a corresponding transmission sequence number of the MAC frame, is generated and inserted into the payload field. The MAC frame is transmitted, including the encrypted payload field, to a counterpart node. A MAC ACK frame acknowledges reception of the transmitted MAC frame; and a DSN is compared in the received MAC ACK frame with the real DSN. An authentication of the counterpart node is performed when the received MAC ACK frame is equal to the real DSN.

摘要： A method is provided for synchronizing time between nodes in a wireless communication system. A reference node transmits a first packet to a correspondent node. Upon receiving the first packet, the correspondent node transmits a second packet with a reception time of the first packet recorded therein, to the reference node. Upon receiving the second packet, the reference node calculates a forward delay time using a transmission time and the reception time of the first packet. The correspondent node receives a third packet with the forward delay time from the reference node, and calculates a reverse delay time. The correspondent node calculates an offset value for the synchronization using the forward delay time and the reverse delay time.

摘要： A method for preventing a replay attack is provided. A prime number is mutually exchanged between a main node and children nodes. The main node generates a Prime Sequence Code Matrix (PSCM) corresponding to the prime number, notifies the children nodes of sequence orders corresponding to the children nodes. The main node selects an arbitrary value of a Prime Sequence Code-1 (PSC1) among a series of values corresponding to an arbitrary node in the PSCM. The arbitrary node computes a Prime Sequence Code-2 (PSC2) subsequent to receiving the PSC1 using a sequence order received from the main node and the prime number. The PSC2 is transmitted to the main node. The main node compares the received PSC2 with the PSCM. The method can be easily applied by supplementing a weakness for a replay attack on the basis of an IEEE 802.15-4-2006 standard and minimizing system load.
