One of the most fundamental aspects of wireless sensor network based applications is that they are designed to monitor a physical quantity, observe a phenomenon or gather information in their surrounding environment. The collected information may become meaningless if the current location of the sensor node is unknown or not related with the observation. In addition to this, there are certain tracking applications, monitoring applications, and geographical routing protocols that put a stringent demand that the location of sensor nodes should be known a priori. This work proposes a distributed...
