Anomalous Attacker Evidence and Detection System in WSN

摘要

Due to the features like distributed structure, open wireless network system etc. the Wireless Sensor Networks (WSN) are pruned to security attacks at various levels. These attacks may have significant influence on the efficiency of WSN. During the anomalous attacks, attackers manage to get unauthorized accesses to the network and harm the network system and services to make them ineffective. A counter mechanism is essential to overcome the influence of the attacks and sustain the efficiency of the network. In that process it is required to find the evidence for the activities of the attacker in the network. In the present research work, an attempt has been made to develop and implement a mechanism or scheme to find the evidence for the existence of an attacker in the network and to provide security measure to the WSN system by filtering the attacker to prevent the attacks. This is achieved by designing and implementing an Anomalous Attacker Evidence and Detection System (AAEDS) as a simple network security measure in wireless sensor networks systems. The proposed AAEDS is designed for homogeneous and heterogeneous WSN models considering single and multiple-sensing detection schemes. The present security measure and its simulation results have been presented and discussed. The results reveal that the present AAEDS works as per expectations for both the types WSNs and can be a proto-type for further extensions.
