    摘要: A method, apparatus and system for displaying topology information of a wireless sensor network includes a plurality of sensor nodes. The method typically includes: receiving node information collected and extracted from the sensor nodes; comparing the received node information with stored node information; computing, when the received node information is unequal to the stored node information, visualization information on a sensor node whose information is not present in the stored node information; and displaying the sensor nodes on concentric circles using the visualization information.

    摘要: A method and system for detecting a suspicious frame in a wireless sensor network that includes: a plurality of sensor nodes, for sending sensed data and data regarding an upper-level node and cluster head node. A data collecting node receives data from the sensor nodes, sends information, and extracts data received from the sensor nodes. A first probability of occurrence of the routing path is computed with respect to training frames, and a second probability of occurrence of a source routing path is computed using the first probability. The second probability is compared with a reference value, and displays an indication notifying an abnormality of the source node according to when the second probability and the reference value.

    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.
