Detection and Correction of Sinkhole Attack with Novel Method in WSN Using NS2 Tool

Abstract

Wireless Sensor Networks (WSNs) are used in many applications in military, ecological, and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. Security is therefore important in WSNs. However, WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources, susceptibility to physical capture, and the use of insecure wireless communication channels. These constraints make security in WSNs a challenge. In this article we discuss security issues in WSNs. In this paper we are discussing a vulnerable sinkhole attack, its implementation and correction.
