Statistical Modeling of Intelligent Transportation Systems Communication Channels

Intelligent Transportation Systems (ITS) is becoming an important paradigm, because of its ability to enhance safety and to mitigate congestion on road traffic scenarios. Realizing the fact that data collection scheme from in-situ test beds for large number of vehicles is always expensive and time consuming, before being employed in large scale,...

Dragon-Lab, network states detection and identification framework: Performance investigation

In this research, a new approach on Internet analysis was adopted. Dragon-Lab is capable of detection, identification, and temporal and spacial localization of Internet backbone anomalous states based on two end-to-end metrics, packet delay and packet loss, and traceroutes information of the measured Internet paths. The anomalous states or...

Performance Analysis and Improvement of Topology Discovery Protocols in Home Networks

The growing popularity of the Internet and the increasing demand of services based on IP have influenced the evolution of home networks. From a simple network constituted by just a PC and a modem, the home network has become a complex environment providing connectivity to several devices with different capabilities. Although service providers...

Energy Conservation of Cooperative Communication over Composite Channels

The studies about the effects of multipath fading and shadowing for wireless cooperative networks are insufficient. Almost all real wireless networks can be modeled by changing the parameters of the composite distribution which models both multipath and shadow fading. This composite distribution makes the analytical calculation of bit error rate...

Protocols for Impulse Radio UWB Ad Hoc Networks

Ultra Wideband (UWB) technology offers an unprecedented opportunity to further accelerate the evolution of wireless communication and expand the application landscape by enabling outstanding capabilities. UWB radio is fundamentally different from most radio technologies, e.g., Bluetooth, WLAN, etc. UWB has many forms. A promising but, not well...
