| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士班 === 94 === Wireless sensor network is composed of many sensor nodes that have abilities of wireless communications. Sensor nodes can sense data or transfer information. When a node senses some data, it can transfer them into the data collecting center with some routing path mechanism. In wireless sensor networks, it is helpful to data transferring when we obtain the locations of many of the sensor nodes and execute that target checking accurately.
This thesis presents a localization mechanism applied to wireless sensor networks. This mechanism can cooperate with RSS estimation method and trilateration to estimate the coordinates of some unknown nodes. It can estimate the sensor nodes that have no GPS with some other nodes that have GPS devices. Thereafter, we can obtain more unknown nodes with some estimated nodes. It decreases the cost that localization tracking of wireless sensor devices. And it finds the location that all sensor nodes are in whole network rapidly.
