“…This include combining the feature of velocity-aware probabilistic with travelling salesman problem in order to increase number of nodes as it is known that routing protocols makes an important task for improving QoS. The obtained result can also be used to enrich findings of Abedi et al (2009) by using velocity-aware probabilistic to reduce the time taken in the route discovery phase by restricting neighbor's distance and number of discovered routes. The same is true when looking at the result of delay time in Fig.…”

Abstract:The current process associated with enhancing the QoS in routing for MANETs has reserved a high importance due to the limitation of available route discovery in dynamic topology. The conventional methods of route discovery schemes in MANETs are commonly designed in order to estimate the number of nodes in routes using the standard probabilistic models. Such models are utilized by estimating the flood in a network using the RREQ packets. However, the current development in mobility, frequent breakages become more common which as a result lead to relocate the properties of same routes. As such, the network may experience additional demands for channel contention and high packets collision rate. For this, we proposed a new scheme for enhancing the routing discovery based velocity-aware probabilistic using AODV properties with link prediction in MANETs. The result of the new scheme was found to outperform the old one in which it offers better ROH, throughput and delay time. This study provides an important insight for predicting the routing failure in a network when using the velocity-aware probabilistic scheme alone.

“…The authors in [45] and [46] worked to improve and enhance existing MANET protocol (AODV) in order to make it suitable for vehicular communication systems. Their improved and enhanced routing protocols were called Position AODV (PAODV) and Direction AODV (DAODV) with improved and enhanced route stability and reduced overall network overhead.…”

“…The design and development of efficient IEEE 802.11p-based DSRC wireless access system that will support efficient and reliable congestion control (CC) techniques is required for effective dissemination of time-critical safety messages in vehicular networks. Many studies have been carried out to validate and evaluate the performance of congestion control techniques [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61]. Several approaches have been employed by researchers for performance evaluation of wireless communication systems such as vehicular wireless communication system with simulation and field test methodology as the two most widely used approaches.…”

Recent advances in wireless communication technologies and auto-mobile industry have triggered a significant research interest in the field of VANETs over the past few years. Vehicular Network consists of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications supported by wireless access technologies such as IEEE 802.11p. This innovation in wireless communication has been envisaged to improve road safety and motor traffic efficiency in near future through the development of Intelligent Transport Systems (ITS). Hence, government, auto-mobile industries and academia are heavily partnering through several ongoing research projects to establish standards for VANETs. The typical set of VANET application areas, such as vehicle collision warning and traffic information dissemination have made VANET an interesting field of mobile wireless communication. This paper provides an overview on current research state, challenges, potentials of VANETs as well the ways forward to achieving the long awaited ITS.Keywords: Vehicular communication, V2V, V2I, ITS, IEEE 802.11p, WAVE, IEEE 1609. IntroductionRoad accidents has been on an alarming increase despite the introduction of several innovative in-vehicle safety-oriented devices such as anti-locking braking system (ABS), seatbelts, airbags, rear-view cameras, electronic stability control (ESC). Several studies have maintained that 60% of the accidents that occur on motorways could be avoided if warning messages were provided to the drivers just few seconds prior to moment of crash [1] [2].The possibility of direct exchange of kinematic data between vehicles over an ad-hoc network environment called a vehicular ad-hoc network (VANET) has been widely perceived by governments, car manufacturing industries and academia as a promising concept for future realization of intelligent transportation system (ITS) thereby achieving safety and efficiency in our nearly overcrowded motorways. The VANET is a sub-class of MANET where the mobile nodes are vehicles. When compared with Mobile Ad-Hoc Network (MANET) and other cellular systems, inter-vehicle communication (IVC) has four major advantages: broad coverage area, relatively low latency due to direct wireless communication, little or no power issue as well as no service fees.In the recent years, car manufacturing industries, academia and government agencies have started putting much joint efforts together towards realizing the concept of vehicular communications in wide scale. Some frameworks are already worked out with the first landmark of standardization processes made by US Federal Communications Communication (FCC) [15] adopted an amendment of the legacy IEEE wireless LAN standard done by an IEEE Task Group (TG). The amendment is denoted by IEEE 802.11p as the platform for Wireless Access in Vehicular Environment (WAVE) which will be used to enable wireless communications between moving vehicles within a coverage distance of 1000m in a free space (i.e. highway scenario) and 300m in non-free space (i....

“…To reduce control overhead over the network Omid Abedi et al [12] improved AODV protocol and designed Prior-AODV. In this protocol, nodes are restricted by which they can't get the RREQ packets and by doing this number of discovered routes are decreased and as a result network overhead is reduced.…”
