摘要：A mobile ad hoc network (MANET) is a collection of independent nodes that communicate with each other through a multi-hop radio network and keep up connections in a decentralized manner. Security remains a major challenge for thesetypes of networks due to their features of open medium, dynamically change in topologies, reliance on cooperative algorithms, absence of centralized monitoring points, and lack of clear lines of defense. Most of the routing protocols for MANETs are thus vulnerable to many types of attacks. Ad hoc on-demand distance vector routing (AODV) is a very efficient routing algorithm. However, it is insecure to the well-known black hole attack, where a malicious node falsely claims that have a best path to a destination node during the route discovery process. This attack becomes more serious when more than one malicious nodes present within network, called multiple black hole attack. In this paper, a defense mechanism hybrid and clustering is presented against to multiple black hole nodes in a MANET.The exploratory results will show that proposed strategy detects and isolate the maliciousnodes from the network proficiently. It will enhance network effectiveness as far as expand throughput, reduce the packet loss and delay of the network. The NS-2.33 simulator instrument will be utilized as a part of it.
