Black Hole and Selective Forwarding Attack Detection and Prevention in WSN

A wireless sensor network is vast domain which is used to while sensing information in various range of applications. The information which is sensed is further carried to base station for processing. While processing of this information, security of the routed data is very important and is challengeable in WSN. This has occurred because in unattended environments WSN is implemented. Researchers have worked on various problem such as robustness, energy consumption, security etc. from an ancient period of time. However current paper focuses more on the routing which is secured as well as trustworthy pattern. Here we have used the concept of active trust routing scheme to defend various kind of attacks during routing of the data packets. Such attacks mainly consist of black hole attack, Denial of service attack and selective forwarding attack. The system also protects the data by hiding during routing by using ECC algorithm, which provides the security. Experimental results prove that the, proposed system improves the security along with prolong network lifetime and low energy utilization and more efficiency throughout the network lifetime.
