Detection of node isolation attack using DNC mechanism in D2D networks

Device to device (D2D) network is a powerful technology that enables D2D communication without additional infrastructure support. There is no authentication procedure in the D2D routing protocol. As a result, it is a very desirable target for attackers and is exposed to several vulnerabilities, including node isolation attacks during sessions. To avoid this problem, a novel denial of node contradiction (DNC) with optimised link state routing protocol (OLSR) is proposed. According to the simulation results, the proposed DNC-OLSR algorithm outperforms the alternatives in terms of the rate at which packets are forwarded, indicating that the proposed routing path is more stable than those of the destination sequenced distance vector (DSDV), ad-hoc on-demand distance vector (AODV) and dynamic source routing (DSR) protocols. However, the DNC-OLSR algorithm is relatively low compared to the other three algorithmic measures of packet loss and the resulting delay. Moreover, the proposed algorithm can provide more reliability and stability for D2D communication.
