Detection and Prevention of DDoS Attacks in Wireless Sensor Networks

Abstract

Wireless Sensor Networks are emerging at a great pace due to their cost effective solutions for the sensitive and remote applications like military, medical and environmental applications (Chatterjee and Pandey in Int J Sci Eng Res 5, 2014) [1]. But due to limited range, memory, processing and power supply, gathering of important remote data from wireless sensors is really challenging. The use of ad hoc network and radio waves for data transmission has also increased the chance for attackers to attack on such networks. Various schemes have been proposed in the past to fight against the attacks in WSN (Sahu and Pandey in Mod Educ Comput Sci 1:65–71, 2014) [2], (Paul et al. in Wireless Sensor Network Security: A Survey. Auerbach Publications, Florida, 2006) [3]. In this paper two methods have been introduced, one is light weight two way authentication method that will prevent majority of attacks in WSN and other is traffic analysis based data filtering method that will detect and prevent DDoS attacks in WSN. The results have been verified using the Network Simulator 2 (NS2) on several performance metrics i.e. throughput, delay, lost packets, energy consumption and PDR.
