Profile Based Scheme Against DDoS Attack in WSN

Wireless Sensor networks (WSN) is an promising technology and have enormous prospective to be working in critical situations like battlefields and commercial applications such as traffic surveillance, building, habitat monitoring and smart homes and many more scenarios. One of the major challenges in wireless sensor networks face today is security. In this paper we proposed a profile based protection scheme (PPS security scheme against DDoS (Distributed Denial of Service) attack. This king of attacks are flooding access amount of unnecessary packets in network by that the network bandwidth are consumed by that data delivery in network are affected. Our main aim is visualized the effect of DDoS attack in network and identify the node or nodes that are affected the network performance. The profile based security scheme are check the profile of each node in network and only the attacker is one of the node that flooded the unnecessary packets in network then PPS has block the performance of attacker. The performance of network is measured on the basis of performance metrics like routing load, throughput etc. The simulation results are represents the same performance in case of normal routing and in case of PPS scheme, it means that the PPS scheme is effective and showing 0% infection in presence of attacker.
