Abstract
In this paper, a new analytic model is built to derive MAC and application-level reliability metrics of IEEE 802.11 based one-dimensional (1-D) vehicular ad-hoc networks (VANETs) in highways, which include Packet Reception Probability, Packet Reception Ratio, T-window Reliability, and Awareness Probability. The metrics derivation starts with the evaluation of point-to-point reception probability through coverage area computation for the impact of hidden terminal problem and concurrent transmissions. The proposed approach facilitates impact analysis of distance dependent DSRC fading channel and application-level analysis. The analytical model takes IEEE 802.11 MAC, 1-D highway geometry, non-saturated message arrival interval, and Nakagami fading channel with path loss into account. The proposed model is validated/verified by extensive simulations. From the obtained numerical results under various network parameters, new important observations are given.

Broadcasting is the primary way of exchanging time-sensitive information in VANETs. However, contiguous loss of broadcasts among vehicles may lead to situations where a vehicle has not heard from a neighbor for extensive periods of time. The goal of this work is to provide an analysis of this invisible neighbor problem and the impact the selected transmission range and packet generation rate of a vehicle have on the occurrences of this problem. Specifically, this work studies this problem in the...

In Vehicular Ad Hoc Networks vehicles periodically send beacon messages in order to gain mutual awareness of each others' presence. Successful reception of such beacons depends on various network conditions, e.g., transmission rate and power, as well as radio fading. Vehicular applications rely on such mutual awareness to supply the driver with safety and efficiency notifications. The Probability of Packet Reception (PPR) is the most common metric that is used to describe network performance, ne...

In Dedicated Short Range Communications (DSRC) based vehicular networking, each vehicle periodically broadcasts control updates (that contain location and speed information etc.) to its neighbors, as a key component of traffic management and safety applications. The effectiveness of such a broadcast feature can be measured by two metrics: (1) the efficiency, or the average rate (number of nodes per sec) to which a source can deliver its broadcast packets, and (2) the reliability, or the average ...

In this paper, a new analytic model is built to derive a closed-form expression of broadcast packet reception rates (PRRs) in IEEE 802.11 based one-dimensional (1-D) mobile ad-hoc networks (MANETs), which is the extension of 1-D MANET analytical model in [7]. Comparing with the existing models, the proposed model accounts for the impact of more factors and network parameters on PRRs such as non-saturated packet arrival in each mobile node, varied transmission, carrier sensing, and interference r...

We develop an accurate analytical model for a dedicated short range communication (DSRC) network that uses the IEEE 802.11 distributed coordination function (DCF) MAC protocol, as adopted by the forthcoming IEEE 802.11p specification for DSRC. The specific focus is on broadcast vehicle-to-vehicle safety messages. We derive explicit expressions for the mean of the total packet delay and the packet delivery ratio (PDR) in an unsaturated network formed by moving vehicles on a highway. Our model is ...

One often cited use case for vehicular networks are applications that relate to emergency vehicles. In addition to the traditional siren, they could use radio communication to warn other vehicles or to preempt traffic lights. Such an application can reduce accident risks during emergency response trips and also help save valuable time. We outline a comprehensive design of such an emergency vehicle warning system that makes full use of inter-vehicle communication, but also encompasses roadside in...

Today's advanced simulators facilitate thorough studies on VANETs but are hampered by the computational effort required to consider all of the important influencing factors. In particular, large-scale simulations involving thousands of communicating vehicles cannot be served in reasonable simulation times with typical network simulation frameworks. A solution to this challenge might be found in hybrid simulations that encapsulate parts of a discrete-event simulation in an analytical model while ...

Abstract In vehicular ad hoc networks (VANETs), cooperation between vehicles is needed for proper performance of safety applications. Beacons are periodically broadcasted by vehicles to inform their neighbors of their information, such that periodic beacons are one of the building blocks that enable the operation of safety applications. Safety applications have their own strict quality of service (QoS) requirements, and they require reliable and timely data communication within networks. When ma...

In this paper, we validate that the deterministic distance-based analytical model can be used to estimate the reliability of one-dimensional (1-D) 802.11 broadcast wireless networks compared with the interference-based analytical model. Therefore, we propose a deterministic distance-based reliability analytical framework for such networks in d-dimensional (d-D, $d \ge 1) scenarios. This framework takes into account the fading channel and hidden terminal problem and makes three commonly used r...

Vehicular ad hoc networks have been used for improving driving experiences by providing safety, efficiency and infotainment applications. Due to high mobility of vehicles, network topology changes frequently, and highly dynamic topology results in lost connection. The geographic routing protocol is used since it does not rely on the establishment of topology. With the popularity of heterogeneous wireless network links, heterogeneous communication range should be taken into consideration when sel...

Abstract Safety applications would be one of the most important on-board implementations in Vehicular Ad-hoc Network (VANET). Broadcasting the Basic Safety Message (BSM) periodically could help drivers increase their awareness range for preventing casualties of traffic accidents or reducing the number of traffic accidents. Usually, the safety applications have more stringent performance requirements (e.g. time delay and reliability) than other kinds of applications. However, because the vehicle ...

In the vehicular ad hoc networks (VANETs), due to the high mobility of vehicles, the network parameters change frequently and the information that the sender maintains may outdate when it wants to transmit data packet to the receiver, so for improving the routing efficiency and reliability, we propose the probability prediction-based reliable and efficient opportunistic routing (PRO) algorithm for VANETs. The PRO routing algorithm can predict the variation of signal-to-interference-plus-noise ra...

A new effective interference-based capacity model was proposed for vehicular ad hoc network safety message broadcast scenario in M. Ni et al. ( Commun. Lett. , vol. 19, no. 4, pp. 621–624, Apr. 2015). This letter is a reconsideration and extension of the model in Ni et al. . First, we point out that the analysis in Ni et al. is incomplete and show a new derivation of the node transmission probability and the SIR distribution accounting for the impact of asynchronous timing of hidden terminals an...

Multi-hop broadcast schemes are commonly used by safety applications to disseminate urgent messages in vehicular ad hoc networks. Sender-based schemes can effectively decrease the collisions caused by simultaneous transmissions among different candidate forwarders and speed up the whole broadcast progress by piggy-backing extra control information in the broadcast message to candidate forwarders. However, the construction and delivery of control information are usually of high cost. In this lett...

In a vehicular ad hoc network (VANET), vehicles attempt to improve safety by emitting safety messages that others receive to increase their awareness of one another. Yet, the conflicting data delivery requirements of safety applications can potentially jeopardize safety itself. While many information dissemination techniques have been proposed to improve data delivery in a VANET, such as flooding and geocasting, evaluations do not focus on measuring safety efficiency in terms of safety applicati...

In a traffic jam or dense vehicle environment, vehicular ad hoc networks (VANETs) cannot meet the safety requirement due to serious packet collisions. The traditional cellular network solves packet collisions but suffers from long end-to-end delay. Third-Generation Partnership Project (3GPP) Long-Term Evolution (LTE) overcomes both drawbacks; thus, it may be used, instead of VANETs, in some extreme environments. We use Markov models with dynamic scheduling and semipersistent scheduling (SPS) to ...
