Due to the movement of mobile nodes, the network topology is changed arbitrarily. Therefore, various intrusions are presented in MANET. For accurate and robust intrusion detection against several attack and deceiving actions, SIEVE technique was designed in MANET. However, node mobility of the ad hoc network restricts the BP algorithm efficiency and it’s difficult to identify attack behavior. Therefore, security is a most important concern in decentralized structure of mobile network. In order to develop the intrusion detection and isolation in MANET, Quantum based Adaptive Topology Control (QATC) technique is developed. In QATC, an adaptive topology control is designed to adjust the transmission range of the mobile nodes to extend the lifetime of networks by retaining the network connectivity. This topology leaves maximum possible nodes connected in a cluster zone with minimum energy consumption and transmission interference. This helps to increase the packet delivery ratio. After this, the arriving and leaving nodes are monitored and the malicious node is identified from the network, through Quantum Mechanism. Quantum mechanism is typically used to detect the malicious node from the network using specific key distribution. Due to this, the malicious nodes are easily detected and isolated, aiming at improving the Malicious node detection rate with minimum time. A simulation result shows that the Quantum based Adaptive Topology Control (QATC) technique achieves higher packet delivery ratio, malicious node detection rate and reduces energy consumption, and time to identify the malicious node compared to state-ofthe-works.
