Vehicular Ad-hoc Networks (VANETs) have been gaining significant attention from the research community due to their increasing importance for building an intelligent transportation system. The characteristics of VANETs, such as high mobility, network partitioning, intermittent connectivity and obstacles in city environments, make routing a challenging task. Due to these characteristics of VANETs, the performance of a routing protocol is degraded. The position-based routing is considered to be the most significant approach in VANETs. In this paper, we present a brief review of most significant position based unicast routing protocols designed for vehicle to vehicle communications in the urban environment. We provide them with their working features for exchanging information between vehicular nodes. We describe their pros and cons. This study also provides a comparison of the vehicle to vehicle communication based routing protocols. The comparative study is based on some significant factors such as mobility, traffic density, forwarding techniques and method of junction selection mechanism, and strategy used to handle a local optimum situation. It also provides the simulation based study of existing dynamic junction selection routing protocols and a static junction selection routing protocol. It provides a profound insight into the routing techniques suggested in this area and the most valuable solutions to advance VANETs. More importantly, it can be used as a source of references to other researchers in finding literature that is relevant to routing in VANETs.

“…A protocol like AODV consumes additional bandwidth due to transmission of periodic heavy beacon messages in intermittently connected VANETs [14,31]. In addition, the maintenance of routing paths in highly mobile environments results in large routing overhead for topology-based routing protocols [5][6][7][8]11]. In order to overcome the restrictions of topology-based routing, position-based routing which is based on location information is introduced [35].…”

“…For the safety of drivers and regulating the flow of vehicles, the drivers have to be alerted to unwanted traffic accidents, traffic congestion, road conditions, and other associated features. The main objective of VANETs is to address these issues by providing the exact and timely information to the drivers [1][2][3][4][5][6][7][8][9][10][11][12].…”

Dynamic Multiple Junction Selection Based Routing Protocol for VANETs in City Environment

VANET (Vehicular Ad-hoc Network) is an emerging offshoot of MANETs (Mobile Ad-hoc Networks) with highly mobile nodes. It is envisioned to play a vital role in providing safety communications and commercial applications to the on-road public. Establishing an optimal route for vehicles to send packets to their respective destinations in VANETs is challenging because of quick speed of vehicles, dynamic nature of the network, and intermittent connectivity among nodes. This paper presents a novel position based routing technique called Dynamic Multiple Junction Selection based Routing (DMJSR) for the city environment. The novelty of DMJSR as compared to existing approaches comes from its novel dynamic multiple junction selection mechanism and an improved greedy forwarding mechanism based on one-hop neighbors between the junctions. To the best of our knowledge, it is the first ever attempt to study the impact of multiple junction selection mechanism on routing in VANETs. We present a detailed depiction of our protocol and the improvements it brings as compared to existing routing strategies. The simulation study exhibits that our proposed protocol outperforms the existing protocols like Geographic Source Routing Protocol (GSR), Enhanced Greedy Traffic Aware Routing Protocol (E-GyTAR) and Traffic Flow Oriented Routing Protocol (TFOR) in terms of packet delivery ratio, end-to-end delay, and routing overhead.

“…Nevertheless, the results of the collaboration of MANET and VANET showed that the performance is not that much over welcoming due to high mobility, varying speed, rapid topology changes, frequent fragmentation and high dynamic network density [13]. In literature three classes of routing protocols are listed namely reactive, proactive and geographical routing protocols [11]. Yet these approaches have their pros and cons and no single routing protocol is able to perform efficiently in all realistic scenarios.…”

Abstract-VANET deployment in real world has become a living reality by the successful allotment of 5.9GHz to Dedicated Short Range Communication (DSRC) by WLAN technologies. Dynamically changing topology and establishment of reliable path between nodes with minimum bandwidth consumption and lesser routing overheads are the main aims of ad-hoc network routing. To exploit effective and reliable communication among vehicles routing is a major factor which needs to be investigated. This paper intends to evaluate the performance of AODV and GOD routing protocols in city scenario under different application types and different fading environment using IEEE 802.11b MAC standard. Simulations are performed using NCTUns 6.0 (National Chung Tung University Network Simulator) and found that AODV performance is better in fading channel even if we increase rician factor. Also the performance of GOD is better in ideal fading (AWGN) channel, although the performance of routing protocols vary from one scenario to other and application traffic.
