Gray-Hole Attack Minimization in IoMT with 5G Based D2D Networks

Abstract

Reliable transmission is vital to the success of the next generation of communications technologies and Fifth Generation (5G) networks. Many sensitive applications, such as eHealth and medical services, can benefit from a 5G network. The Internet of Medical Things (IoMT) is a new field that fosters the maintenance of trust among various IoMT Device to Device (D2D) modern technologies. In IoMT the medical devices have to be connected through a wireless network and constantly needs to be self-configured to provide consistent and efficient data transmission. The medical devices need to be connected with sophisticated protocols and architecture to handle the synergy of the monitoring devices. Today, one of the commonly used algorithms in D2D communication is the Optimized Link State Routing protocol (OLSR). The OLSR is considerably good at effectively utilizing the bandwidth and reserving the paths. One of the major attack against the OLSR is the Node isolation attack, also known as the Gray hole denial of service attack. The Gray hole attack exploits the vulnerabilities present with sharing the topological information of the network. The attackers may use this topological information to maliciously disconnect the target nodes from the existing network and stops rendering the communication services to the victim node. Hence, considering the sensitivity and security concerns of the data used in e-Health applications, these types of attacks must be detected and disabled proactively. In this work, a novel Node Authentication (NA) with OLSR is proposed. The simulation experiments illustrated that the proposed protocol has an excellent Packet Delivery Ratio, minimal End-End delay, and minimal Packet loss when compared to the Ad-hoc On-Demand Distance Victor (AODV) protocol and the proposed authentication scheme was able to protect the OLSR protocol from a node isolation attack.

Resource Allocation Based on SFLA Algorithm for D2D Multicast Communications

“…As a result, D2D communication technology has been developed, and it now presents an important part in the modern 5G cellular network [1,2]. One of the basic 5G technologies is D2D communication network, which is described as a collection of devices that can communicate with each other wirelessly without the need for an infrastructure or a central authority [3]. The rapid increase in CUs, combined with the high demand for improving quality of service (QoS), has resulted in a decrease in spectral resources, which is one of several main factors restricting the development of modern communication networks [4,5] with the foreseeable explosion in the number of wireless devices, and the continuing development of multimedia services [6].…”

On the Effect of Malicious User on D2D Cluster: CSI Forgery and Countermeasures

“…However, there exist potential security threats in clusterbased D2D communications when a malicious user is a member of the cluster. Several types of D2D attacks have been reported recently such as eavesdropping, free-riding, CSI forgery, denial-of-service, key compromise impersonation, and gray-hole attacks [12], [13], [14], [15].…”
