Efficient protocol prediction algorithm for MANET multimedia transmission under JF periodic dropping attack

Abstract

Mobile ad hoc network is prone to denial of service attack. Jellyfish is a new denial of service attack and is categorized as JF Reorder Attack, JF Periodic Dropping Attack, JF DelayVariance Attack. In JF PeriodicDropping Attack, intruder node intrudes into forwarding group and starts dropping packets periodically. Due to JF Periodic Dropping attack, the delay in the network increases and throughput decreases. In this paper a comparative performance analysis of three reactive routing protocols i.e. AODV, DSR and TORA used in mobile ad hoc network under JF Periodic Dropping attack is done. This work is specially done for multimedia transmission i.e. video and voice. If we have a mobile ad hoc network in which probability of occurrence of JF Periodic Dropping attack is high and also if it requires time efficient network multimedia service for information exchange then TORA protocol is to be chosen. If it requires highmultimedia throughput and consistent service in the network then AODV protocol is recommended. An algorithm has been proposed depending upon the analysis done particularly for multimedia transmission in MANET which will help in choosing the best suited protocol for the required network parameters under JF Periodic Dropping attack.
