Intelligent transport system (ITS) applications are attracting more attention both in industry and in research. However, there are still myriads of problems facing the implementation of ITS applications. In vehicular networks, issues such as rate adaptation poses a great challenge. Due to the fact that the environment in which vehicular networks operate is heavily subjected to rapid changes in ...

The performance of protocols and architectures for upcoming vehicular networks is commonly investigated by means of computer simulations, due to the excessive cost and complexity of large-scale experiments. Dependable and reproducible simulations are thus paramount to a proper evaluation of vehicular networking solutions. Yet, we lack today a reference dataset of vehicular mobility scenarios th...

Vehicular ad hoc networks can play an important role in enhancing transportation efficiency and improving road safety. Therefore, direct vehicle-to-vehicle communications are considered as one of the main building blocks of a future Intelligent Transportation System. The success and availability of IEEE 802.11 radios made this technology the most probable choice for the medium access control la...

In Vehicular Networks, communication success usually depends on the density of vehicles, since a higher density allows having shorter and more reliable wireless links. Thus, knowing the density of vehicles in a vehicular communications environment is important, as better opportunities for wireless communication can show up. However, vehicle density is highly variable in time and space. This pap...

On-demand data retrieval is a crucial routine operation in a vehicular sensor network. However, on-demand data retrieval in a vehicular environment is particularly challenging because of frequent network disruption, large number of data readings and limited transmission opportunities. Real world vehicular datasets usually contain a lot of data redundancy. Motivated by this important observation...

this presentation will cover, appearance of normal nerve versus tendon; anisotropy (advantage and disadvantage); special case carpal tunnel; tendinopathy; nerve impingement; special case cubital tunnel.

Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel ...

The Multichannel Operations IEEE 1609.4 is an emerging standard which support the co-existence of safety (CCH Channel) and non-safety (SCH Channel) message application in vehicular networks. This strictly concerns on the transmission slot synchronization of CCH/SCH based on Wireless Access in Vehicular Environments (WAVE) to achieve QoS requirements (i.e. to improve packet delivery ratio and re...

The exchange of information between vehicles is a challenging issue for future Transportation applications. In vehicular Ad-Hoc network, the vehicles are interconnected with each other and they have not any additional infrastructure along the roadside. Vehicular Ad-hoc networks are eminent from other types of Ad-hoc networks. The Ad-hoc network attributed to their features such as infrastructur...

Vehicular ad hoc network (VANET) is one of the largest areas of interest in wireless technology because it provides very wide variety of services in the field of transportation. Intelligent Transportation System (ITS) provides a set of standards for Vehicular Communication networks. The vehicular network provides many useful applications and advantages. The multimedia applications, which are ba...
