An Effective CBHDAP Protocol for Black Hole Attack Detection in Manet


Objective: The various features of mobile adhoc networks (MANET’s) are open medium, dynamic topology and absence of centralized monitoring point which introduces various security challenges. One among the security attacks are defined as the black hole attack in this article. Methods: In this paper we introduce a protocol for detecting and avoiding the black hole attacks in MANET’s by an efficient Crypto-key based Black Hole Detection and Avoidance Protocol (CBHDAP). Findings: The suggested protocol generates a group key using Diffie-Hellman (DH) based key agreement black hole detection algorithm then the generated key is forwarded to the authenticated group members. The validation of the nodes in the route from the source to the destination is done before initiating the transmission. The black hole attacks are avoided during transmission by considering the parameters such as time taken for Route Reply (RREP), hop count, Packet Delivery Ratio (PDR) are used. To validate the performance of the proposed approach, it is compared with the existing protocols for the metrics such as detection probability, throughput, end-to-end delay, etc. Improvements: The validation results prove that the CBHDAP provides optimal results for all the metrics like detection probability, throughput, E2E delay etc when compared with the algorithms existed. Keywords: CBHDAP, Blackhole Attack, Diffie-Hellman Algorithm, MANET’s, Security Attacks
