MALICIOUS ATTACK DETECTION AND PREVENTION IN AD HOC NETWORK BASED ON REAL TIME OPERATING SYSTEM ENVIRONMENT
Jithesh Puthenkovilakam ., M Tech Student · 2013
This paper deals with Real Time Operating System (RTOS) based secure wormhole detection and prevention in ad hoc networks. The wormhole attack can form a serious threat to wireless networks, especially against many ad hoc network routing protocols and location based wireless security systems. A wormhole is created in the ad hoc network by introducing two malicious nodes. These two nodes form a worm hole link and message is transmitted through this link. The next part of the work is to detect the wormhole link by defining worm hole detection and prevention algorithm. After detecting suspicious links, one node performs a verification procedure for each suspicious link. The detection procedure and verifying procedure of suspicious worm link are used for further prevention of wormhole attack in the ad hoc network.
