Black-Hole and Wormhole Attack in Routing Protocol AODV in MANET
Mobile Ad hoc NETwork (MANET) is a self-configuring network that is formed automatically via wireless links by a collection of mobile nodes without the help of a fixed infrastructure or centralized management. The mobile nodes allow communication among the nodes outside the wireless transmission range by hop to hop and the forward packets to each other. Due to dynamic infrastructure-less nature and lack of centralized monitoring points, the ad hoc networks are vulnerable to attacks. The network performance and reliability is break by attacks on ad hoc network routing protocols. AODV is a important on-demand reactive routing protocol for mobile ad hoc networks.
