Abstract: An electronic tag collision preventing method for using a tag number presumed according to a tag state is provided to recognize a plurality of tags rapidly and clearly by determining the number of time slots based on the estimate of the tag number of round. An RFID(Radio Frequency ID) tag transmits data to a reader by determining arbitrary time slot(S10). The reader determines the state of the time slot and counts the number of collision slots, idle slots and success slots for present round(S20). The reader deactivates the tag to the termination of the reading sequence(S30). An algorithm is selected according to the state of the time slot(S40). The tag number of round is presumed as algorithm(S50). The number of time slots defined in the following round is determined by the presumed tag number(S60).

Abstract: A packet analysis equipment of a wireless sensor network including an embedded board is provided to supply packet analysis information in a remote access by using Ethernet and detect a channel used in the wireless sensor network. An RF(Radio Frequency) transmitter and a receiver(235) transmit and receive a plurality of sensor nodes and a packet. A microcomputer(233) analyzes and processes the received packet. An embedded board performs remote access with a developer. The embedded OS(Operating System) of an embedded linux or a Windows CE(Consumer Electronics) base embedded OS are used by the embedded board. The embedded board is used as the server. A personal computer of the developer is used by the client.
