“…In this section, we (1) evaluate the performance of the SADTR; (2) make comparisons with four CR-VANETs routing schemes: CoRoute, 10 EPDMR, 11 SSR, 12 and DTR; 13 (3) make comparisons with three routing schemes: a social-aware routing of Bubble Rap, 32 a copy-forward routing of Spray and Wait, 33 and a benchmark routing of Epidemic. 34 We have introduced these CR-VANETs routing schemes [10][11][12][13] in related works. The Bubble Rap 32 is a community-based social routing strategy.…”

“…We have also proposed a delay tolerant routing scheme to improve the packet delivery ratio of CR-VANETs. 13 Different from these researches, in this article, we utilize the social characteristics which are relatively stable and less volatile than the spectrum changing and node mobility features in CR-VANETs. We design an efficient social-aware routing scheme which can improve the packet delivery ratio as well as reduce the overhead ratio.…”

Cognitive radio–based vehicular ad hoc networks can solve the problem of limited spectrum resource and growing vehicular communication service demands in intelligent transportation systems, and thus, it receives much concern recently. In cognitive radio–based vehicular ad hoc networks, the high mobility of vehicles and the dynamic spectrum activity of cognitive radio make routing in such networks a great challenge. Some routing researches have been proposed in cognitive radio–based vehicular ad hoc networks with single-objective optimization and neglecting the nodes’ social behaviors which can improve the network performance. From this perspective, we propose a social-aware routing scheme for cognitive radio–based vehicular ad hoc networks, with the purpose of increasing the packet delivery ratio and decreasing the overhead ratio. First, we analyze the social centrality of primary users to offer an accuracy spectrum hole measurement. Moreover, we develop a social community partition algorithm to divide secondary users into intra-community and inter-community groups. Furthermore, considering the tradeoff between the packet delivery ratio and the overhead ratio, we adopt different replication policies and forwarding ranks in different community communication processes. In the intra-community communication process, we employ the single-copy policy and the contact duration rank. In the inter-community communication process, we utilize the optimized-binary-tree replication policy and the bridge coefficient rank. Simulation results show that our social-aware routing scheme achieves the higher package delivery ratio and the lower overhead ratio when compared with the existing cognitive radio–based vehicular ad hoc networks routing schemes and other standard routing schemes.

“…We also proposed some forwarding schemes for the CR-enabled vehicular networks. 22,23 These researches are focused on the non-real-time applications, with the objective of the delivery ratio maximization. The latter one applies the social characteristics of both PUs and SUs to improve the packet delivery ratio and the overhead ratio.…”

The Internet of vehicles is an essential component for building smart cities that can improve traffic safety and provide multimedia entertainment services. The cognitive radio–enabled Internet of vehicles was proposed to resolve the conflict between the increasing demand of Internet of vehicles applications and the limited spectrum resources. The multi-hop transmission is one of the most important issues in cognitive radio–enabled Internet of vehicles networks. Nevertheless, most existing forwarding solutions designed for the cognitive radio–enabled Internet of vehicles did not consider the urban expressway scenario, where primary base stations are densely installed with small coverage areas. In this case, it is difficult to ensure that the sender and the receiver of the same cognitive radio link have similar channel availability statistics, which makes cognitive radio links more likely to be interrupted. To address this challenge, we develop a multi-hop forwarding scheme to minimize the end-to-end delay for such networks. We first formulate the delay minimization problem as a non-linear integer optimization problem. Then, we propose an approach to select the relay candidates by jointly considering the high mobility of vehicles and the unique cognitive radio spectrum usage distributions in urban expressway scenarios. Finally, we propose the low-latency forwarding strategies by considering the channel availability and the delay cost of different situations of relay candidates. Simulations show the advantages of our proposed scheme, compared with state-of-art methods.
