摘要：A collection of mobile nodes having ability to organize in a free manner without any fixed infrastructure is known as Mobile Ad hoc Networks (MANETs). Among various types of wireless networks, MANETs are one of the most usable network types. Various routing protocols are there to route the optimal path in an ad hoc network. But because of the wireless nature of MANETs, security of networks is a major issue. It is prone to various types of malicious attacks. Jamming attacks are one of them. These occur by transmitting continuous radio ways to inhibit the transmission among sender and receiver. These attacks effect the network by decreasing the network performance. Previously there had been considerable research in the field of increasing the performance of network by using routing protocols. In our research work we are improving the performance of mobile ad hoc networks under jamming attack by using an integrated approach. The proposed work includes a network with high mobility, using IEEE Along g standard with improved AODV (Ad hoc On Demand Distance Vector) routing protocol parameters. FTP and Video conferencing with high data rate are being generated in the network. The performance of network is measured with respect to the QoS parameters like throughput, retransmission attempts, network load and media access delay. OPNET (Optimized Network Engineering Tool) MODELER 14.5 is used for simulation. The results of simulation demonstrate that the overall performance of network with jamming attack has been increased by using the integrated approach.
