With high velocity, and sparse distribution of vehicles on the road, routing a packet to its destination is one of the major challenges in Vehicular Ad Hoc Networks (VANETs). To reduce the complexity of transmissions, only context-aware data is required for successful transfer of alerts to the passengers as unnecessary information may cause a performance bottleneck at some point in VANETs. To address this issue, in this paper, we propose a new context-aware congestion resolution protocol called as-minimum calculated desired time (MCDT) for Intelligent Data Dissemination in VANETs. In the proposed scheme, first the link stability is computed and then, a peak stable zone is constructed which is used to estimate the virtual connectivity of the nodes. A module for recovery of lost link using minimum angle method is also proposed. The proposed scheme can be used for vast industrial applications, where there is a need of contextual-aware information dissemination with less delay, and higher accuracy. The proposed scheme is evaluated in different network scenarios by varying the parameters such as velocity, and density of the vehicles. The results obtained yield an improvement of more than 90 % in end-to-end delay (E2ED), 11.75 % in download speed, 7 % enhanced resource utilization, and a decrease of 16 % in overhead in the proposed scheme as compared to other state-of-the-art existing schemes.

SUMMARYIn a vehicular ad hoc network, trust between vehicles is vital to efficiently transmit the data among vehicles. Secure node selection is based on the trust value that a node can calculate during its operations in a dynamic network. This will increase the confidentiality level of the network, thus improving the network performance. However, defining confidentiality is not a crisp task, rather it can range between certain limits. A fuzzy-based inference engine can be used to optimally define these limits. In this paper, a fuzzy-based trust prediction model is proposed to effectively compute the trust of other vehicles for the secure path formation in vehicular ad hoc networks. In the designed approach, each vehicle models the trustworthiness of the neighbors in its cognitive range to dynamically select the relay nodes that can be used for data transmission and the election of the appropriate path for routing in vehicular ad hoc network environment. The results and analysis of the proposed model over the standard protocols are presented using simulations.

“…The proposed mechanism stated in [3], Simplified Gateway Selection Scheme (SGSS), enabled vehicles to connect to the Internet and other mobile services continuously; it described two types of vehicles: vehicles within the coverage area had a dual interface and communicated directly to the UMTS base station transceiver. UTRAN and vehicles that move along the road looking for an associate to be used to connect to the UMTS base station transceiver had a single interface.…”

This paper presents a new clustering mechanism for the multi-hop relay in vehicular communication. In the proposed mechanism, the cluster-head selection is implemented using the enhanced hybrid wireless mesh protocol (E-HWMP) protocol, which is based on the IEEE802.11p and IEEE802.11s standards. Then, multi-hop routing is designed for VANET in Wireless Mesh Networks (WMNs). Therefore, the main aim of this study is to enhance the integration of VANET with a cellular network (i.e., LTE). As a result, the coverage can be extended. The proposed E-HWMP mechanism is evaluated by the NS2 simulator, and the VanetMobiSim is used as a mobility generator. The proposed E-HWMP mechanism is compared to the existing mechanism based on the packet's delivery ratio, packet loss, throughput, overhead, and average end-to-end delay. The results demonstrate that the proposed E-HWMP mechanism outperforms the existing clustering mechanism.
