Detection and Prevention of Black Hole Attack in MANET

The wireless Ad-hoc network is one of the active and vibrant in the field of communication and network. Mobile Ad-hoc network [MANET] is one of the field of wireless networks that provides the research and development of the wireless networks in various applications. The 2-way routing protocol is being implemented for the detection of black hole attack in MANET that has same data packet to be transmitted from source to the destination as a replication via two protocols such as AODV (Ad-hoc on-demand routing) protocol and DSR (destination sequence routing) protocol. The problem defined in this paper is the black hole attack that deprives the normal transmission of data packets from source to destination by introducing the malicious node that drops or discards the packet without being transmitted to the destination thus causing the loss of the packet, end to end delay and reduction in the packet delivery ratio. The solution to the above problem is the usage of the 2-way routing protocol that assures the effective outcome of detecting the malicious nodes by traversing the packet across another destined route. The solution comprising the 2-way routing protocol is comparatively effective than the existing mechanisms in a way that it detects the route of the malicious node and traverses the packet via another route using different protocol simultaneously.
