Abstract

The Basic issue of wireless sensor networks is Localization. Localization gives Positional information of sensor nodes. For obtaining location information of sensors we require Localization techniques (algorithms). For the deployment of sensor nodes, coverage and rescue operations location information is essential. Many applications such as routing and target tracking are all location dependent. Two Localization algorithms are used to obtain the node positions. Range Based & Range Free Localization techniques which are used to locate the nodes. Individually these two techniques are having limitations. To solve these limitations CDL (Combined and Differentiated Localization approach) method is proposed which uses DV -hop localization algorithm to calculate distance between the nodes. High Location accuracy is achievable by CDL method in reducing the location error. This paper is proposed with advances in Localization methods along with their location error results. The aim of this work is to find out the precise location of sensor node.
