A Simulation Analyses of MANET’s Attacks Against OLSR Protocol with ns-3

Abstract

During the last decade, the Internet of Things (IoT) became an emerging technology, it is exploring in every area of human life. The IoT provide facilities to identify and communicate the Smart devices, this last can transfer data in Mobile Ad hoc Networks (MANETs) across all active devices without the need for a centralized approach. The connection between MANETs and Internet of Things opens new ways or provision of services in smart environments and challenging issues in its networking aspects also. Simultaneously, MANETs are threatened by different attacks, which aim to degrade the network’s performances. In this article, we simulate and study the impact of Link-spoofing, Data-flooding and Replay attacks with Optimized Link State Routing Protocol (OLSR) (RFC 3626) on using ns-3 simulator. In this work, we took into consideration the density of the network by the number of nodes included in the network, the speed of the nodes, the mobility model and even we chose the IEEE 802.11ac (WIFI 5) standard, in order to have a simulation, which deals more general and more real scenarios. To analyze the impact of the attack on the network, we chose the Quality of Service (QoS) metrics for performance evaluation: Packet delivery rate (PDR), Normalized routing load (NRL) and End-to-End delay (EtED).
