Security Measures of WSN Networks by Avoiding Message Replay Attacks

摘要

The challenges area of Ad Hoc networks is attributable to their lack of establishedinfrastructure, requirement for redistributed management, dynamic topology, and wireless channelcharacteristics. We have a tendency to study the performance of IEEE 802.15 MAC protocolbelow varied conditions such as using Power control method and other techniques that improvebetter than of other Ad Hoc networks. To satisfy these needs a WSN networks is used to supportsadaptively and improvement across layers of the protocol is needed. The WSN network improvesbetter than other Ad Hoc networks types because in WSN the data only transferred when the both(sender /receiver) satisfied otherwise they kept on sleeping mode. The major challenge of thispaper is to avoid the attacks because WSN continuously performed better than other technologies.The attack that is classified in the section 3; from these attack classification we analyze that theMessage Replay attack is one of the more powerful attack that continuously touch with destinationnode and destination node assumes that the packets was received soon but an malicious nodecan't transferred the packets to the destination node. So in this stage message dropping start andthe performance of the entire network goes down. We implement the secret key methodology inthe network scenario so that each node communicates to other node only when if they having asecret key otherwise communication could not occurred. From the results studied it was observedthat we improve the performances of WSN and avoided the Message replay attacks
