Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infras...

We develop joint vehicle tracking and road side unit (RSU) selection algorithms suitable for vehicle-to-infrastructure (V2I) communications. first design an analytical framework evaluating systems based on the extended Kalman filter. A simple, yet effective, metric that quantifies performance is derived in terms of angular derivative a dominant spatial frequency. Second, RSU algorithm proposed ...

This paper presents a novel unmanned aerial vehicle (UAV)-aided mobile edge computing (MEC) architecture for vehicular networks. It is considered that the vehicles should complete latency-critical computation-intensive tasks either locally with on-board computation units or by offloading part of their to road side (RSUs) collocated MEC servers. In this direction, hovering UAV can serve as an RS...

Protecting the location privacy of drivers is still one of the main challenges in Vehicular Ad-hoc Networks (VANETs). The changing of pseudonym is commonly accepted as a solution to this problem. The pseudonyms represent fake vehicle identifiers. Roadside Units (RSUs) play a central role in the existing pseudonyms distribution solutions. Indeed, the VANET area should totally be covered by RSUs ...

The vehicular ad hoc network, combined with the distribution of roadside units (RSUs), play a significant role in reducing accidents and traffic jams by sending warning emergency messages to drivers real-time. However, communication is not always available owing lack RSUs, reliability data access control, avoid such problems we have proposed new strategy for deployment least possible number RSU...

Unmanned-aerial-vehicle (UAV)-enabled intelligent transportation system (ITS) is an advanced technology that can provide various services including autonomous driving, real-time creation of high-definition maps, and car sharing. In particular, a UAV-enabled ITS be realized through the combination traditional vehicular ad hoc networks (VANETs) UAVs act as flying roadside units (RSUs) at outskirt...

In the underlying work, problems faced during message dissemination in conventional Vehicular Energy Networks (VENs) like lack of security, breach personal identities, absence trust between vehicle owners, etc., are tackled. this study, a Blockchain (BC) based announcement system is proposed for VENs to ensure secure and reliable network. The three-layered comprising layer, storage layer BC lay...

OBJECTIVES To survey of the structure, processes and organisation of renal satellite units (RSUs) in England and Wales (Phase 1), and to compare the effectiveness, acceptability, accessibility and economic impact of chronic haemodialysis performed in RSUs compared to main renal units (MRUs) (Phase 2). DATA SOURCES Phase 1: all renal satellite units in England and Wales. Phase 2: haemodialysis...

In the Quito historical center, due to its narrow streets, vehicular congestion is very frequent. Intelligent vehicles can be used, which have fully automatic driving, but need interact with each other. The manner in smart through vehicle networks, require installation of an infrastructure called RSU (Road Side Unit) that uses IEEE 802.11p standard and allows sending information more distant pl...

Vehicular Adhoc Networks (VANETs) enable vehicles to act as mobile nodes that can fetch, share, and disseminate information about vehicle safety, emergency events, warning messages, passenger infotainment. However, the continuous dissemination of from their one-hop neighbor nodes, Road Side Units (RSUs), VANET infrastructures lead performance degradation VANETs in existing host-centric IP-based...
