Vehicular Ad Hoc Networks (VANETs) have been widely studied, and the deployment of such networks is likely to happen soon as the required technology and commercial opportunities are already available. Most of applications proposed for these networks require a localization mechanism with reasonable accuracy. In addition to applications, most protocols rely on the availability of a system that determines...
Recent advances in wireless communications and the availability of Heterogeneous Wireless and Mobile Networks (HWMNs) have enabled the development of interesting applications. The main objective of HWMNs is the delivery of wireless services to potential applications in personal, local, campus, and metropolitan areas. However, in these networks, there is a need of gateway discovery mechanisms that...
Recently, IEEE 802.11-based wireless networks have been widely adopted as the main access technology. This type of wireless network is know for its low cost, easy deployment and easy configuration. However, the radio range of access points in an IEEE 802.11-based wireless network is limited, thereby mobile nodes have to switch their access points frequently in order to maintain connections in a mobile...
As in many other distributed systems, time synchronization is an important service in wireless sensor networks. Most wireless sensor network applications are targetted at retrieving information from surrounding environments. In many situations, the temporal property of a physical event is critical to wireless sensor network applications. There are many time synchronization techniques for wireless...
Image-based rendering (IBR) has attracted recent attention mainly due to its low requirements for generating new scenes based on a sequence of reference images. IBR has paved the way for a new class of application, the free viewpoint television (FTV), which allows the viewer to interactively control the camera and move freely within a scene. IBR can also be used to render complex 3D virtual environments...
Vehicular Ad Hoc Networks are a promising technology that provides several interesting new functionalities to drivers and passengers. These services are spread through a wide variety of applications, each with specific requirements in terms of latency, jitter and bandwidth, among other metrics. For this reason, it is crucial to provide mechanisms that can be used to offer different levels of communication...
Virtual simulation has been playing an important role in many areas including gaming, training, e-learning, and etc. At the mean time, real-time emergency response system is attracting more and more attention due to its significance to reduce the casualties and properties lost when disasters come. Indeed, a highly responsive and effective real-time response system depends on a well designed architecture,...
