With the rapid growth of high data rate applications, significant amount of energy is consumed by base stations' equipment. In order to save energy, it is better to deploy fewer base stations (BSs) or switch off as many as possible. However, this is usually attained at the expense of quality of service (QoS). In this paper, we deploy fewer BSs to reduce(More)
—In this paper, we propose a novel double cluster-head routing scheme for motorway vehicular networks, which is generically modelled and can be applied to single or multiple cluster-head routing schemes, to save a significant amount of energy through adaptive sleep cycles while maintaining the required quality of service. Real vehicular and data traffic(More)
Traditionally the locations of the base stations (BSs) in an indoor environment are optimised based on either traffic demand, signal to noise ratio (SNR), energy consumption or coverage area. However, considering only one of these parameters does not yield an optimum design, which is needed for efficient cost-effective planning with the required quality of(More)
This paper aims to show the effects of road congestions arising from motorway roadworks on the performance of vehicular mobile networks. Using vehicular traces from loop Ids on a length of the M4 motorway in the UK, the impact of congestion due to speed control measures and lane closures in a section of the coverage area is simulated to show the resulting(More)
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 vehicles’ buffers needed to hold packets. In this paper, we study the impact of the above mentioned parameters and report original(More)
The need for reducing the carbon footprint and reducing the operation expenditure (OPEX) in communication networks poses several challenges in the study, design and deployment of energy efficient networks in different environments. Recently there has been a considerable effort to green vehicular networks which is very challenging due to the very dynamic(More)
