Physical layer security (PLS) is an essential way to provide security to users in wireless networks against active or passive attacks. The quantification of the provided security is measured through secrecy outage probability and outage probability. For cognitive vehicular networks (CVN), PLS can increase the amount of the quality of services in infotainment applications. Due to the broadcast nature of the wireless channels, it is challenging to achieve the perfect secrecy between the transmitting and receiving nodes. Furthermore, in CVN, when resources are being shared in an underlay manner, the need arises to find the highest and lowest achievable quantification of performance measures for poor fading scenarios. The knowledge of the maximum achievable performance helps to design and develop the anti eavesdropping solutions. In a particular direction, firstly, this paper finds the closed-form expressions of first-order secrecy metrics over multiple input multiple output 2x2 Nakagami-m channel for vehicular networks. The derived closed-form expressions are further utilized to find the upper and lower bounds of secrecy outage probability, and outage probability using the integral bound method for CVN. The derived bound provides the knowledge of the region over a valid signal-to-noise ratio for which the maximum and minimum achievable performance can exist. To restrict the amount of eavesdropping, the convex optimization-based approach is proposed. The optimization method helps secrecy metrics to remain in a specific region of the value. Therefore, the work provides insights over the classical approach and the information-theoretic approach. These works enhance the knowledge to prepare the anti-eavesdropping methods for connected cars. Moreover, the derived analytical expressions demonstrate the impact of the wireless medium on secrecy performance while the derived bound demonstrates the impact of the magnitude of wireless fading parameters.

“…From the vehicular communication perspective, several V2V half-duplex relaying (HDR) techniques have been studied and investigated in the literature. The communication between source-destination (S-D) nodes could be established by a road access point (AP) [28], a mobile vehicle [29] and multiple mobile vehicles in [30]. Ilhan et al [31] studied two different cooperative relaying schemes.…”

Performance Analysis of Full-Duplex Vehicle Relay-Based Selection in Dense Multi-Lane Highways

This paper considers a dual-hop vehicle-to-vehicle (V2V) communication system equipped with full-duplex relays (FDRs) in the millimeter-wave networks. The performance of this network is studied in a dense multi-lane highway considering cooperative best vehicular relay selection strategy. In fact, two different FDR schemes are analyzed for the given network. In the first scheme that is called self-interference (SI) vehicle relaying selection, the FDR models the source-relay and the relay-relay links by one channel state information (CSI) coefficient (i.e., a single channel estimation of the two links), while in the second scheme that is called individual SI vehicle relaying selection, the CSI of the source-relay and the relayrelay links are estimated separately. Moreover, relay-destination link is modeled by one CSI coefficient in both aforementioned schemes. Dissimilar to traditional V2V schemes where either line-of-sight (LOS) or non-line-of-sight (NLOS) propagation is considered, and the effect of the blockage on V2V communications is not taken into account when analyzing the performance, in this paper, we propose a probabilistic model capturing the occurrences of LOS and NLOS propagations, which depend on the movement of the vehicles between the central and adjacent lanes. Thus, the movement of the vehicles between any two adjacent lanes is assumed to take place independently and is deemed to be according to the Poisson distribution. This vehicle movement model considers the blockage between the source and destination links. In this vein, a LOS link is considered available when the center lane is clear of vehicles between the source and destination nodes, and an NLOS link is assumed otherwise. Furthermore, a Nakagami-m fading channel model is considered due to its excellent representation of the V2V communication environment. The LOS/NLOS probabilities combined together with the probability of blockage are used to analyze the system performance. The cumulative density function expression of the signal-to-interference-plus-noise ratio at the relay is derived for both relaying schemes. Moreover, the lower bound expressions of the end-to-end outage probabilities are developed and used to express throughput. Finally, the theoretical results postulated and presented here are verified by the numerical simulation for a variety of parameters.
