An Effectual Data Transmission Approach to Prevent Black Hole Attack in Mobile Adhoc Networks

The dynamic nature of infrastructure in MANET makes security as a critical issue. Due to mobility of nodes, network is easily affected by several types of attacks. In particular black hole attack cause packet dropping, misrouting the information from source to destination. To prevent a network from the effects of the black hole attack, we propose a most reliable data transfer scheme to detect the black hole nodes in the network and ensure the availability, reliability, confidentiality of the information. First, the proposed scheme detects the black hole node using trust active and node recommendation values. Second, the reliability and confidentiality of the information is achieved by using verifiable secret sharing scheme. The proposed algorithm is implemented on AOMDV protocol. The simulation results show the proposed algorithm achieves the better packet delivery ratio, misbehavior detection efficiency, fewer packets overhead and low end to end delay than the existing schemes.
