Comparison of AODV, DSR and OLSR Performance Under Black Hole Attack in Mobile Ad Hoc Networks
2020
BlackHole attacks manipulate MANET routing protocols by deceiving nodes sending data into believing that the malicious Black Hole node has the optimal route available for data transmission to the intended recipient node.The ability to implement the appropriate routing protocol is essential in minimising the impact Black Hole attacks have on MANETs.In this study, the AODV, DSR and OLSR protocols were simulated under no attack as well as under Black Hole attack scenarios to determine which of these protocols performs best.The results were analysed using the performance metrics of Throughput, End-to-End delay and PDR.The results of the simulations show that AODV is more vulnerable to Black Hole attacks than DSR or OLSR.Furthermore, the results show that the adverse effects of a Black Hole attack on Throughput, End-to-End delay and PDR were more significant in AODV as opposed to DSR, which had the best overall performance.Future work to analyse the effects that Black Hole attacks have on the performance of Mobile Ad-hoc Networks in terms of mean delay time, packet overhead and memory usage could also be conducted.
