20100241655 | APPARATUS FOR AND METHOD OF TRANSMITTING SENSING DATA OF SENSOR NODE FOR PROACTIVE DATA FILTERING IN WIRELESS SENSOR NETWORK - An apparatus for and a method of transmitting sensing data of a sensor node for proactive data filtering in a wireless sensor network are provided. In the apparatus and method, a request query of sensing data and timer parameters are received, local sensing data sensed in the sensor node in response to the received request query are detected, a driving time of a timer applying the timer parameters based on the request query is set, and the local sensing data are transmitted when the local sensing data do not overlap sensing data of a neighboring sensor node within a wireless reception range of the sensor node by overhearing the sensing data of the neighboring sensor node during the set driving time of the timer. Thus, since a data transferring path is selected considering the remaining energy of the node, the energy exhaustion of the node is distributed, thereby improve the lifespan of the network. | 09-23-2010 |
20100278163 | METHOD OF DELIVERING DATA IN WIRELESS PRESONAL AREA NETWORK - Provided is a method of delivering data in a wireless personal area network. One of nodes forming the wireless personal area network broadcasts data including the address and the sequence number of one node to a plurality of other nodes, and broadcasts one of the data and other data to the other nodes depending on whether the data is received from the other nodes within a predetermined time. Accordingly, all the nodes on the network can receive data reliably and simultaneously power consumption is reduced, and thus the life of the network is extended. | 11-04-2010 |
