Detection and prevention of DDOS attack in WSN for AODV and DSR using battery drain

Wireless network with a merit of sensing and processing information is known as wireless sensor network (WSN). It consists of small sensor nodes with transducer, battery, microprocessor along with storage media. It is economical and simple solution for a variety of applications. Open nature of WSN leads it to defenseless for various security threats. Several security attacks black hole, wormhole attack, DDOS attack etc. are possible to compromise the information and sensor node in network. Distributed Denial of Service (DDOS) attack is such kind of attack which aims to disrupt the network by draining resource capability. Attacker not only sends worthless messages to increase network traffic but also degrades the life of node and network. In WSN life of network is directly proportional to battery capacity. Thus draining in battery energy directly degrades the life of node. This work observed it as severe problem and proposed a solution to overcome the problem of power draining due to DDOS attack. Qualnet 5.0 simulator has been used to simulate and evaluate the performance of proposed solution for AODV and DSR routing protocols in WSN.
