MANET (Mobile ad hoc NETwork) is a mobile Ad hoc network. It is self-configuring network which is infrastructure less in nature. In MANET different nodes are connected through wireless links. Each node is free to move i.e. no central controller is available. There are several types of attacks in MANETs like jamming, selective packet drop attack etc. In this paper, the authors will discuss about jamming attack. A novel technique will be proposed to detect and isolate jamming attack. Experimental results show that proposed technique is more efficient than the existing one.
