Wireless NanoSensor Networks (WNSNs), i.e., networks of nanoscale devices with unprecedented sensing capabilities, are the enabling technology of long-awaited applications such as advanced health monitoring systems or surveillance networks for chemical and biological attack prevention. The peculiarities of the Terahertz Band, which is the envisioned(More)
Wireless NanoSensor Networks (WNSNs) will allow novel intelligent nanomaterial-based sensors, or nanosensors, to detect new types of events at the nanoscale in a distributed fashion over extended areas. Two main characteristics are expected to guide the design of WNSNs architectures and protocols, namely, their Terahertz Band wireless communication and(More)
With the increasing concern for reliability and quality of service, power grid in many countries is undergoing revolution towards a more distribute and flexible " Smart Grid ". In the development of envisioned smart grid, situational data awareness takes a fundamental role for a number of crucial advanced operations in the areas of sensing, communication,(More)
Nanonetworks consist of nano-sized communicating devices which are able to perform simple tasks at the nanoscale. The limited capabilities of individual nanoma-chines and the Terahertz (THz) band channel behavior lead to error-prone wireless links. In this paper, a cross-layer analysis of error-control strategies for nanonetworks in the THz band is(More)
This paper describes an anticipated mobility between the two access technologies WLAN and UMTS considered as complementary technologies for next generation networks integration. We propose to apply anticipated vertical handover (AVHO) in the integration of the third generation wireless communication (3G) from one side and WLAN 802.11 from the other side.(More)
— over the past few years, mobile operators are faced with enormous challenges. Of such challenges, evolved user demands on personalized applications. Telecommunications industry as well as research community have paid enormous attention to Next Generation Networks (NGN) to address this challenge. NGN is perceived as a sophisticated platform where both(More)
