A Survey on Localized Detection and Centralized Verification Scheme for Efficient Secure Communication in WSN

Abstract

The threats in network are very common and have been identified as key issue which affects the QoS performance of entire network. To improve the performance, a novel Localized Detection and Centralized Verification (LDCV) scheme is proposed. The intrusion detection system monitors the network flow and features of packets at each fraction. The monitoring of network flow is performed in each sensor available as named localized detection. Each sensor node has been intimated about the generic values of flow, payload, and hop count and so on at different sessions when there is no such traffic available. The sensor node uses this information in monitoring the incoming flow to measure the trustworthy of the data packet. Similarly, the verification of nodes trust has been activated to be done in a centralized way which measures the trustworthy based on the logs available. Using the logs available, the nodes access trust measure (ATM) is computed to perform intrusion detection. At the detection of intrusion attack, the source node itself would flood the information in the region. The performance in intrusion detection and network threat detection has been increased.
