This paper aims to guarantee the quality of service (QoS) to motorway drivers with regard to multimedia (triple play-video, voice, and data) communications, which requires substantial analysis of the characteristics of vehicular traffic profiles on motorways. We therefore perform an analysis of real vehicular traffic data taken from inductive loops on a motorway and then develop our own simulator...
Studying the vehicular traffic profiles on a motorway gives us a unique insight into the dynamics of drivers' behaviour. This behavioural study provides us with an important utility to develop applications and deploy infrastructure according to the need. Consequently, it enables us to design and develop accurate motorway vehicular simulators and robust medium access control (MAC) protocols that can...
In vehicular ad hoc networks (VANETs), routing schemes play a vital role in data dissemination. As data dissemination in a timely and efficient manner is critical for safety-related applications, in this paper we introduce a location based routing algorithm namely geographic routing, which significantly reduces the packet dropping probability and the total number of packets in the network compared...
Fuelled by the phenomenal growth of vehicular and air traffic, motorways and airports are considered to be among the most dynamic environments known. Providing adequate and reliable communication facilities to motorway and airport users is extremely challenging due to the high variability of the environments in which they operate. Moreover, maintaining quality of service (QoS) for all traffic classes...
For data dissemination using vehicular ad hoc networks (VANETs), it is essential to determine the end-to-end (e2e) delay, the packet dropping probability (PDP), the number of vehicles required, and the size of the vehiclespsila buffers needed to hold packets. In this paper, we study the impact of the above mentioned parameters and report original simulation results in a typical city scenario based...
To provision various multimedia communication services with guaranteed quality to motorway drivers and future autonomous vehicles, substantial work is required to analyze the characteristics of vehicular traffic profiles on the motorways. To this end, in this paper, we first analyze some real vehicular traffic data taken from an inductive loop on the motorway 'M4' in Wales over the last 5 years, and...
A constantly growing interest in cellular and mobile technology has lead to a need for MAC protocols specifically designed to accommodate high bandwidth multimedia services with high mobility (such as vehicular networks) unlike conventional cellular telephony systems. This paper presents the design and performance evaluation of a MAC protocol for a motorway environment with audio sources and variable...
