Non-cryptographic Detection Approach and Countermeasure for JFDV Attack
Avani Sharma, Rajbir Kaur · 2014
Because of inherent characteristics of mobile ad hoc networks (MANETs), security attacks have pronounced effect on performance of the network. JellyFish Delay Variance (JFDV) attack is a kind of protocol compliant, cross layer attack that reduces throughput of network by delaying data packets during forwarding them. In this paper, we propose a non-cryptography approach which is resilient against JFDV attack for Optimized Link State Routing (OLSR) protocol. Proposed approach labels a node as misbehaving node after comparing its performance against Delay Threshold. Process of re-routing is initiated to route the data packet through the path consisting of non-attacking nodes. We analyze the performance of our approach on Packet Delivery Ratio (PDR) of network with different fraction of JF nodes and system size. Through extensive simulation and result, we show that proposed approach provides a secure architecture to thwart JFDV attack in MANET.
