LOCALIZATION OF SENSOR NODES TO DETECT MALICIOUS NODES: PROBLEM DEFINITION
Keywords:
Wireless Sensor Networks, Sensor Node.Abstract
Localization is the mechanism by which position of the nodes which are transferring the data will be analyzed. The transferred data will reach the destination. As the number of nodes on the network increases so does the security problems. In order to tackle the problems of the malicious nodes ,certification authority will be introduced within the localization process. The localization can be range free or range based in nature. The localization process can depend upon the distance. If the localization depends upon the distance then it is known as range based algorithm. If the localization does not depend upon the distance then it is known as range free algorithm. In the proposed paper we study and compare the various localization mechanisms available.
