摘要：The challenges area of Ad Hoc networks is attributable to their lack of established infrastructure, requirement for redistributed management, dynamic topology, and wireless channel characteristics. We have a tendency to study the performance of IEEE 802.15 MAC protocol below varied conditions such as using Power control method and other techniques that improve better than of other Ad Hoc networks. To satisfy these needs a WSN networks is used to supports adaptively and improvement across layers of the protocol is needed. The WSN network improves better 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 this paper 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 the Message Replay attack is one of the more powerful attack that continuously touch with destination node and destination node assumes that the packets was received soon but an malicious node can’t transferred the packets to the destination node. So in this stage message dropping start and the performance of the entire network goes down. We implement the secret key methodology in the network scenario so that each node communicates to other node only when if they having a secret key otherwise communication could not occurred. From the results studied it was observed that we improve the performances of WSN and avoided the Message replay attacks.
