A new geometric algorithm for localization in sensor networks

Similar to many technological developments, wireless sensor networks have emerged from military needs and found its way into civil applications. Today wireless sensor networks has become a key technology for different kinds of smart environments and an intense research effort is currently underway to enable the application of wireless sensor networks for a wide range of industrial problems. Wireless networks are of a particular importance when a large number of sensor nodes have to be deployed and/or in hazardouse situations. The research field in this paper is supposed to be on this issue that a lot of these sensors are distributed randomly and just a few of them are aware of their position [e.g. by GPS]. The purpose is to determine the best way that allows all the nodes to find their position. This paper presents an effective geometric algorithm for localization. Result of implementation show that this algorithm can be a better substitution for current methods because of lower expense and simple implementation.
