Last year an ultrasonic distance measurement system for point-to-point measurements was created. As a continuation of that thesis the goal is to develop an accurate system for planar node localization. There are three major parts. First, the creation of the node itself. Secondly a communication network between all the nodes must be developed. The third and major part is the development of a mathematic algorithm to control error propagation when measuring multi-hop paths.

Node localization and sensor networks are becoming immensely popular and economically important in our nowadays lives. This popularity is influencing our way of living. This blog attempts to create a link between society and engineering technology. A brief look into how sensors and sensor applications influence our lives and to what extend it is influenced will be provided.  Some innovative and economically successful sensor applications will be discussed.
