Road traffic information helps a driver in selecting an appropriate route to the travel destination by avoiding congested road segments. A vehicular ad hoc network (VANET) offers an alternative approach to collect road traffic information without a wired infrastructure and centralized storage. This paper proposes the road traffic collecting (RTC) protocol to gather road traffic information in a VANET on city roads. The key protocol operation is the query dissemination that steers a query message over a set of predefined routes towards the destination location. To collect road traffic information, nodes participating in the query dissemination include their own velocity to the query message so that congestion information on different positions of road segments is gathered. A node nearest to the destination that receives the query message returns the query reply containing road traffic information of the forward route back to the source. Unlike existing broadcasting and geocasting protocols, our proposed protocol uses the message exchange pattern that increases the reliability of query delivery under a collision channel. The simulation on a large network with high vehicle densities and simultaneous query sessions is conducted to evaluate the protocol performance in terms of the percentage of road segment coverage and the query response time under the presence of MAC layer collisions. The results show that RTC can collect 100 % of road traffic information over a set of predefined routes under a few number of parallel query sessions while an existing protocol that mainly uses a broadcast message can achieve only 40-70 %. For a large number of query sessions, RTC achieves 65-80 % of target road segments depending on the vehicle density with the average query time bounded to a few seconds.

.Vehicular Ad Hoc Networks (VANETs) are autonomous and self-configurable wireless ad hoc networks and considered as a subset of Mobile Ad Hoc Networks (MANETs). MANET is composed of self-organizing mobile nodes which communicate through a wireless link without any network infrastructure. A VANET uses vehicles as mobile nodes for creating a network within a range of 100 to 1000 meters. VANET is developed for improving road safety and for providing the latest services of intelligent transport system (ITS). The development and designing of efficient, self-organizing, and reliable VANET are a challenge because the node's mobility is highly dynamic which results in frequent network disconnections and partitioning. VANET protocols reduce the power consumption, transmission overhead, and network partitioning successfully by using multicast routing schemes. In multicasting, the messages are sent to multiple specified nodes from a single source. The novel aspect of this paper is that it categorizes all VANET multicast routing protocols into geocast and cluster-based routing. Moreover, the performance of all protocols is analyzed by comparing their routing techniques and approaches.

“…The basic idea of this type of routing is distributing message from the source node to some nodes in a special geographical region. Inter-Vehicles Geocast (IVG) protocol proposed by Bachir and Benslimane (2003) and Robust Vehicular Routing (ROVER) proposed by Kihl et al (2007) are examples of this type.…”

Vehicular communication is one of the fast growing and promising technologies for a safe and comfortable driving environment. These technologies do not end up with economic and safety ramifications, but also extended with other informational and entertainment oriented services. Data are being propagated multi-hop between source and destination vehicles for many real-life applications. Clustering is one of the effective and scalable solutions for data dissemination in wireless ad hoc networks. Though many cluster-based methods have been proposed for multi-hop data delivery in vehicular ad hoc networks, most of them do not consider the real-time changes in the network topology or imposes large penalties in routing such as unstable clusters, broken links, updating route tables. In order to address these issues, we propose a broadcast based routing protocol for inter-cluster data dissemination in this study that works on real-time vehicle information. Unlike, most existing routing algorithms, it only uses hello messages to obtain routing information without many other control messages. In addition, it alleviates the storage of routing information in every node, which largely reduces the overheads in routing. We performed extensive simulation to demonstrate the effectiveness and efficiency of the proposed routing protocol. Results show that the proposed protocol outperforms other approaches in terms of average delay, average delivery ratio and average number of hops.
