Abstract
Wireless communication with the sensing power makes Wireless Sensor Networks (WSN) profitable now. However, the protection of data through WSN remains a challenge. The difficulties due to the battery life time, data storage space and computation cause the nodes of WSN to compromise. The adversary nodes cause the diversion of data route the base station. Sometimes those nodes may alter the data so that the base station will do misinformed decisions. It becomes difficult to detect and separate the correct nodes to avoid the process of false information passed by the adversary nodes. The security and routing of data is very important in the operation of WSN. A new method is aimed at providing analysis and design of strategy to detect and isolate adversary node in WSNs. The method is Angle Based Adversary Node Detection (ABAD). The threshold value is taken into consideration form the quality of service parameters and the node is decided whether it is a normal or an adversary node. All simulations are achieved in the network simulator tool that uses various scenarios (25 nodes and 50 nodes).
