Impact analysis of rank attack with spoofed IP on routing in 6LoWPAN network

The routing protocol — RPL for low power and lossy networks is the fundamental routing convention of 6LoWPAN. The introduction of rank idea in RPL serves numerous intentions, including path optimization, prevention of loops, and managing control overhead. Since the RPL is currently used as the main routing protocol, for large scale low-power and lossy networks, the concept of “Rank” can lead to a vulnerable performance due to the internal threats in RPL based networks. It is studied that an attack on the rank property with legitimate IP can degrade the network performance in the aspect of the delivery ratio and end-to-end delay. And this can be further degraded if node's IP gets spoofed by the attacker node. This work discuss the impact of rank attack when the attack is launched by the node having a spoofed IP address. Performance is measured in terms of packet delivery ratio and end-to-end delay of packets. The observations show that the Rank attack with spoofed IP has more impact on the degradation of delivery ratio.
