Abstract: A device and a method for testing performance of RFID middleware are provided to measure load of the RFID middleware by generating virtual tag data from a virtual reader, and measure a time difference between tag request time and result receiving time by generating a request of tag data from a virtual application system. A user interface(60) receives the first and second information from a user. The first information defines a tag and a reader to generate tag data provided to the RFID middleware(20). The second information defines an interested reader, the interested tag data, and a filtering value to enable the RFID middleware to collect, classify, and process the tag data. The virtual reader(30) transmits the tag data generated by the first information to the RFID middleware. The virtual application system(10) requests and receives the result processing the tag data generated from the virtual reader according to the second information. A controller(40) measure the load of the RFID middleware by checking the tag data received from the virtual reader, and measure the tag request time and the result receiving time.

Abstract: A method and an apparatus for setting a routing path in a wireless sensor network are provided to remove a long transmission path problem during data transmission only through an existing address allocation method and communication between a parent device and a child device without using a separate message for searching an existing path. A search unit searches existence of a destination address indicating an address of a receiving device receiving transmission data, a parent address of the destination and an ancestor address of the destination. When an address is searched in the search unit, an LQI(Link Quality Indicator) determiner transmits the data to the receiving device if an LQI value of the address exceeds a preset value.

Abstract: A method for preventing and overcoming beacon indirect collision is provided to prevent the indirect collision between nodes in an ad-hoc network which operates in the beacon mode, thereby more stably operating the network. A new node collects the beacon information of neighboring nodes(501), assigns time slots desired to use according to a time slot allocation algorithm(502), broadcasts a time slot allocation messages to neighboring nodes at the beacon point of time of the neighboring nodes(503), and then checks whether a time slot disallowance message is arrived or not for the twice period of the beacon cycle(504). If the disallowance message is not arrived, the new node determines that a time slot overlapped with the time slot assigned to oneself does not exist, and then transmits beacon signals to the neighboring nodes(505).

Abstract: An entity sensor node for entity management, a manager sink node, and an entity management method are provided to enable a manager to confirm the state of each entity having mobility in real time by forwarding the location information and sensing information of each entity, to which an entity sensor node having a communication function is attached, to a manager sink node through a sensor network. An entity sensor node(200), connected with a manager sink node through a sensor network, comprises a sensor part, a data processing part(220), and a situation cognition processing part(230). The sensor part measures surroundings and creates sensing information. The data processing part(220) communicates with one or more neighbor entity sensor nodes, acquires the location information of the neighbor entity sensor nodes, and transmits the acquired location information and associated sensing information according to a request from the manager sink node. The situation cognition processing part(230), if a measured value contained in the sensing information exceeds a preset critical value, generates an alarm, and transmits an alarm message to the manager sink node.
