A SECURITY THREATS AND AUTHENTICATION APPROACHES IN WIRELESS SENSOR NETWORKS

Abstract

Wireless sensor network are used for the replacement of wired networks and it communication is much faster compared to wired networks. The conducted simulation results and corresponding analysis demonstrate the proposed algorithms state of art schemes in terms of detection accuracy and effectiveness. Authentication key establishment protocols between a sensor and a security manager in a self-organizing sensor networks.WSN are produces the various types of attacks such as (Sybil, Wormhole, Sinkhole, Selective forwarding attack ) It uses the low battery power and low in energy. Hackers can hack the data while in sending from one system to another. The malicious detection is mainly used the protocol of (STC-OLSR)to find the shortest path algorithm. It compare the cost with neighbor nodes to find the least difference to delivers the packets from source to destination in it.
