摘要：With the rapid growth in wireless technology such as laptops, wireless phones, wireless sensors, the importance of wireless technology becomes more and more prominent. Wireless networks can be wireless sensor networks (WSN), mobile wireless sensor network, ad- hoc wireless sensor network and mobile ad-hoc network. Mo bile ad-hoc network (MANET) has got tremendous success and attention due to its self maintenance and self configuration properties or behavior. It consists o f autonomous group of mobile nodes having ability to communicate with each other without any fixed central base station. Mobile nodes communicate with each other using routing protocols. The dynamic topology of the network and absence of central base station makes MANETs vulnerable to various security threats like exploiting vulnerabilities of routing p rotocols and injecting spurious packets in the network, tampering the contents of the packets, dropping packets, impersonating another node etc. These threats deteriorate the performance of the network, thereby, decreasing the reliability and throughput of the network. Protecting the network from these threats is one of the major challenging security issues in MANETs. In this paper, we proposed a technique to prevent and detect malicious node attack in MANETs using Cluster head Gateway Switch Routing (CGSR) protocol. The proposed technique detects the malicious node attack on the basis of miss ratio. The technique is implemented using MATLAB and the simulation results show that the technique works efficiently for the prevention and detection of malicious node attack.
