Research on Qualitative Analysis of LEACH with Wormhole attack in Wireless Sensor Network

Wireless Sensor Networks are real time distributed systems often deployed in adhoc fashion with self - configuring capability along with ability to connect wirelessly at extremely low cost, makes WSN a promising technology for wide range of applications. Routing is a major issue in development of Wireless sensor network. Due to resource constrained nature, sensor networks are vulnerable to harmful attacks including S in k hole, W ormhole, Sybil attacks which affects the performance of various routing protocols. In this paper, primary focus has been made to analyze the network performance of LEACH with wormhole attack. Emphasis is made to propose and develop a scheme for detection of wormhole attack from intermediate and surrounding threats.
