Vehicular Ad hoc Networks (VANETs) can help reduce traffic-related accidents by broadcasting Emergency Messages (EMs) in advance between vehicles. Due to the high-speed mobility of VANETs and attenuation of the wireless signal, reliable and fast transmission of EMs is a challenging task. Such as the chosen next-hop vehicle may have driven away from the neighborhood of the sender before receiving the EM, and rerouting may increase the delay when the EMs encounter transmission failure. To this end, we propose a Speed and Position aware Dynamic Routing (SPDR) for EM dissemination in VANETs. First, we introduce a speed metric dynamic greedy routing to provide a dynamic hop-by-hop rebroadcast of the EM. SPDR dynamically shrinks the Routing Decision Area (RDA) range based on the velocity variance of candidate neighbors and prioritizes the farthest vehicle in the shrunk RDA as the optimal next-hop, enhancing the reliable transmission of EMs. Then, we present a collaborative forwarding strategy to enable candidate neighbors to collaborate in communication. In case of transmission failure, SPDR elects the candidate vehicle close to the destination as the forwarder to reduce rerouting. Simulations in a practical motorway scenario using NS-2 and VanetMobiSim show that SPDR outperforms the existing protocols in terms of message delivery ratio, network throughput, and average dissemination delay.INDEX TERMS Vehicular ad hoc networks (VANETs), dynamic routing, emergency message (EM), nexthop selection, velocity variance.

“…VANETs offers many types of applications such as effective management applications [9][10][11] (route planning and urban traffic monitoring), cost-effective applications 12,13 (vehicle location-based services, shortest route planning, and so on), entertainment applications (audio and video sharing, Internet facility, social networking, and so on) and security applications [14][15][16][17] (rear vehicle warning, road status information, road ice testing, and so on). Moreover, the communications among vehicles in the wireless environment are simply targeted when they are sharing sensitive information with other vehicles in that group.…”

The advent of group‐oriented communication applications in Vehicular Ad Hoc Networks (VANETs) has trigger research on lightweight privacy‐preserving Secure Group Communication (SGC) in VANETs. In view of this, many researchers proposed privacy‐preserving, authentication, and key agreements schemes. However, these schemes need to address the dynamic nature, heavier processing loads, massive storage, and higher communication. In this direction, we proposed a framework for lightweight dynamic SGC with privacy‐preserving and authentication in VANETs, encompassing (i) A lightweight Elliptic Curve Cryptography (ECC)‐based two‐party key agreement and its extension to a Dynamic Group Key Agreement, in which fixed Road Side Unit (RSU) acts as Group Controller (GC) with superior computational ability than the On‐Board Unit equipped on the vehicles. (ii) An identify‐based authentication and privacy‐preserving schemes using only two lightweight operations XOR and hashing. (iii) A lightweight encryption and decryption with Exclusive Or (XOR) and hashing only. And (iv) a formal security model for SGC in VANETs. The security analysis shows that the proposed system provides confidentiality of session key, anonymity, secure session key enhancement, and immune to password guessing attack, replay attack, insider attack based on an assumption of the computational G‐ECDDH problem. The experimentation is done for authentication, group key agreement, encryption, and decryption times by a varying number of vehicles in the group to 10, 20, 40, 60, 80, and 100 and shown that the proposed technique is taking considerably less computation than other techniques. So the proposed technique is highly desirable in VANETs.

A vehicular ad hoc network (VANET) is a special mobile ad hoc network that provides vehicle collaborative security applications using intervehicle communication technology. The method enables vehicles to exchange information (e.g., emergency brake). In VANET, there are many vehicle platoon driving scenes, where vehicles with identical attributes (location, organization, etc.) are organized as a group. However, this organization causes the issue of security threats (message confidentiality, identity privacy, etc.) because of an unsafe wireless communication channel. To protect the security and privacy of group communication, it is necessary to design an effective group key agreement scheme. By negotiating a dynamic session secret key using a fixed roadside unit (RSU), which has stronger computational ability than the on-board unit (OBU) equipped on the vehicle, the designed scheme can help to provide more stable communication performance and speed up the encryption and decryption processes. To effectively implement the anonymous authentication mechanism and authentication efficiency, we use a batch authentication scheme and a shared secret key mechanism among the vehicles, RSUs and trusted authority (TA). We design an efficient group secret key agreement scheme, which satisfies the above communication and security requirements, protects the privacy of vehicles, and traces the real identity of the vehicle at a time when it is necessary. Computational analysis shows that the proposed scheme is secure and more efficient than existing schemes.
