Simulation of Wireless Sensor Networks Localization with OMNeT

Wireless sensor networks are being developed for use in monitoring a host of environmental characteristics across the area of deployment, such as light, temperature, sound, and many others. Localization plays an important role in wireless sensor network applications when the positions of nodes cannot be decided beforehand or, if nodes are mobile. A distributed, scalable algorithm for estimating the localization of nodes in a wireless sensor network is described in detail. Simulations were performed with the software of OMNeT++. The results show that in the presence of 5% measurement range errors, 20 percentages beacon node population, and average neighbors of 12 nodes, the estimation errors of the algorithm proposed are about 25% on average. It is also shown that, the algorithm performs well with up to 35% measurement range errors
