This work investigates the topic of Vehicular Named Data Networking (VNDN). We propose a new VNDN routing protocol and address negative effects caused by receiver mobility. In particular, we identify problem Reverse Path Partitioning (RPP) that often prevents messages from reaching Content Requesters, degrading application performance. To mitigate RPP mechanism called Auxiliary Forwarding Set (AFS). AFS takes several mobility factors as inputs extends NDN core philosophy identifying an extra...
In this work, we address the negative effects of network partitions, caused by low vehicle densities, on performance Vehicular Named-Data Networking (VNDN) applications. We target scenarios with high mobility and propose two different solutions. For cases infrastructure support, present idea VNDN agent delegation. approach, develop a communication mechanism for Road Side Units (RSUs), deploy it in RSUs along roads, delegate content retrieval to these enabled RSUs. lack support novel store...
The developments in wireless sensor networks, mobile technology and cloud computing have been pushing forward the concept of intelligent or smart cities, each day smarter infrastructures are being developed with aim enhancing well-being citizens. These advances can provide considerable benefits for diverse components cities including health which be seen as facet dedicated to healthcare. A defy that stills requiring appropriate responses is development mechanisms detect issues patients from...
Vehicular networks are seen as the basis for development of intelligent transportation systems. Therefore, and in order to take advantage benefits from these systems, standards that meet specific characteristics vehicular was required. The "Wireless Access Environments" (WAVE) developed fulfill this need. This standard presents an architecture based on a division into multiple channels, which set certain types applications, it uses switching mechanism selection since only one channel is...
A crucial problem in distributed systems is the probability of failure occurrence resources. Recent studies have been searching different ways for improving execution time applications and enhancing fault-tolerant mechanisms. In many cases testing performed using simulated environments. This work presents implementation a simulator computational grids prone to resource failures. The presented allows evaluation topologies monitoring services on grid including job scheduling, automatic...
In the context of climate change and Intelligent Transportation Systems, this work is part an ongoing research focused on potential electric mobility in reducing pollutant emissions by moving vehicles. Targeting Mindelo city Cabo Verde, West Africa, we evaluate impact greenhouse gas emissions, including CO, CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> , NOx, HC, PMx. With aim, relying data provided local transport authorities,...
In this thesis, Vehicular Named-Data Networking (VNDN) refers to the use of communication model over Ad-hoc Networks. With aim addressing problems caused by mobility efficiently support VNDN communications in highly mobile traffic scenarios, various contributions were proposed scope thesis. These include a routing protocol, able address such as broadcast storms and message redundancy, well solutions enable content advertisements for reverse path partitioning, network source mobility....
