Abstract: One of the key issues in wireless sensor networks is the precise determination of positions of arbitrarily located sensor nodes with low complexity and lowest energy consumption. Depending on the application, different accuracy levels are required. It can be distinguished between coarse- grained algorithms with lower hardware requirements, but low precision and fine-grained algorithms with high accuracy, but which are also very resource-intensive. In this paper we investigate and compare the precision of selected methods with respect to the network geometry and highly inaccurate distance measurements.

Keywords: wireless sensor networks, geosensors, localisation, accuracy, precise positioning
