Design of mechanisms to detect and Prevent sybil attacks in leach for Wireless sensor network

Abstract

Wireless Sensor Network WSN is a collection of sensor nodes newlinewhich communicate with each other through any wireless communication newlinemedia WSN consists of a number of tiny low battery powered energyconstrained newlinesensor nodes used for sensing data processing with wireless newlinecommunication components Each sensor node has the ability to sense its newlinesurroundings to perform limited computation and communicate wirelessly newlineSensor nodes have many constraints like limited resources low energy high newlinesecurity vulnerability unreliable communication unattended operations etc newlineThey are highly vulnerable to attacks and threats Hence various mechanisms newlineare needed to detect and prevent attacks and threats newline newline
