Detection of Wormhole Attack Using USOR
Mobile Ad-hoc NETworks (MANETs) are infrastructure less networks and this kind of networks are more vulnerable to different types of attacks. There are several number of schemes proposed for providing security and protect against various attacks. The wormhole attack also affects the routing at various levels because it is more dangerous to different routing protocols. The authors’ approach for wormhole detection enables the receiver to detect wormhole nodes using unobservable routing. They proposed an efficient method to identify the wormhole nodes exists in the routing path and rediscover new routes from the source node to target node.
