Hybrid Technique for Detection of Denial of Service (DOS) Attack in Wireless Sensor Network

Wireless Sensor Networks (WSNs) are deployed at aggressive environments which are vulnerable to various security attacks such as wormholes, denial of attacks and sybil attacks. There are various intrusion detection techniques that are used to identify attacks in a network with high accuracy level. This paper has focused on denial of service attack, since it is the most common attack that affects the environment severely. Therefore a new hybrid technique combining Hidden Markov Model with Ant Colony Optimization (HMM+ACO) has been proposed that gives improved performance than the other techniques.
