Study on Selection of Useful Bacon node in Range Free Localization Algorithm in WSN

Abstract

Localization is an important part in wireless sensor network and briefly used it in WSN. Because, from it we get the required information to identify current location of sensor node. Now this become an interest field among the researcher. To determine the physical location of a node is known as localization in wireless sensor network. There are large number of small nodes in WSNs. The characteristic of these nodes is that, low energy, limited processing capability, low cost and most important part that they can identify their current location without GPS and manual configuration. They can exchange their information with their neighbor node in ad-hoc fashion. There is different different method to determine the location. For different location different method can give accurate result. Our main concern is to get accurate result. Localization can be challenges for some special scenario such as: fire detection in a big forest. In this paper I try to present a short survey on the localization technique that used in wireless sensor networks (WSNs).
