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)
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 nanomachines 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)
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)
During April-July 1993, anthropometric measurements of 296 children aged 6-10 years from four different Bedouin groups of Lebanon and Syria and interviews with their caretakers were conducted to determine child nutritional status and to examine the association between their diet and nutritional status. The children were from the semi-settled Bedouins of(More)
Wireless Sensor Networks (WSNs) are one of the most promising solutions for smart grid applications due to advantages, such as their low-cost, different functionalities, and successful adoption to smart grid environments. However, providing quality of service (QoS) requirements of smart grid applications with WSNs is difficult because of the power(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)
Wireless networks have resource limitations; in a dense area, cellular spectrum resources are insufficient and affect the system performance. A Long Term Evolution (LTE) network aims to serve heterogeneous users with different QoS requirements. Traditional approaches need new infrastructure and degrade performance of delay sensitive applications, which may(More)
