Query processing method of multi-dimensional property in sensor network, Query processing system of multi-dimensional property in sensor network and Recording medium using by the same

摘要

Query processing method for a multi-dimensional attribute of the sensor network, the query processing system and recording medium which records them on a multi-dimensional attribute in a sensor network is disclosed. ; Query processing method for a multi-dimensional attribute of the sensor network according to the present invention, ; Comprising: (a) a sink node of the plurality of sensors in a sensor network comprising a node at the sink node on their location information and the radio wave to the parent decision message including the hop number of the sink nodes; (B) propagating the parent decision message including own node, a sensor node in the sensor receives the decision message from the parent sink node position information, hop count in the sensor node as a child node in a hierarchical sensor; And (c) of their sensor node to the sink node from the terminating node has received the parent decision message location information, the largest number of hops among the children of the sensor nodes, and a sector bit according to the sensor property information a node sensing parent selection message including a transmitting hierarchically. ; According to the present invention, can reduce the number of data transfer involved in the topology of the sensor network to reduce the energy consumption, not the data transfer is performed to unnecessary nodes to distribute effectively the management range of the sensor network between parent and child nodes by If it is possible to perform the administration of an effective sensor network, a sensor of a particular sensor node not work, and can reconfigure the sensor network without having to route changes, it caused the update to the attribute values ​​of a certain range of the sensor node, sensor by sending a change of a node attribute value, the attribute value of the at least only to a parent node through the comparison of the liver there is an effect capable of easily performing the management of the network.
