Abstract: Wireless Sensor Network (WSN) is being emerged as a prevailing technology in future due to its wide range of applications in military and civilian domains. These networks are easily prone to security attacks since these networks are deployed unattended and unprotected environment. Some of the inherent features like limited battery and low memory make sensor networks infeasible to use conventional security solutions which needs complex computations and high memory. There are lot of attacks on these networks which can be classified as routing attacks and data traffic attacks. Some of the routing attacks in sensor nodes are wormhole, black hole and selective forwarding attack.In a black hole attack,compromised node drops all the packets forwarding through it. Ad hoc On-demand Distance Vector routing (AODV) is a very popular routing algorithm. However, it is vulnerable to the well-known black hole attack where a malicious node falsely advertises good paths to a destination node during the route discovery process. In this project, a defense mechanism is presented against multiple black hole nodes in IEEE. 802.15.4 based wireless sensor networks. In last, performance (Throughput, PDR and End-to-End delay) of security algorithm against the black hole nodes is analyzed.
