摘要：Mobile ad hoc network (MANET) is a set of wireless nodes that dynamically self-organising into a
changeable topology to design the network using any preceding framework. Due to open nature of wireless
communication medium, wireless networks are susceptible to jamming attacks. Jammers interfere with the legitimate
nodes by sending strong jamming signals. Legitimate nodes can successfully transmit only between the gaps of the
jamming signals. Thus, it is important to detect and mitigate a jamming attack as soon as it happens in order, to
effectively take counter measurements. There are various types of jamming, but the signature of jamming attack is to
degrade the performance of the network. Based on this observation, we proposed an enhanced scheme for mitigating
jamming attack using bandwidth and packet delivery ratio algorithm. Using OPNET simulation, the attack can be
detected through increase in performance criteria and successfully mitigated by our proposed scheme. We have
analysed the results using OPNET 14.5 simulator.
