—We propose and evaluate a number of of frequency selection strategies for nano-scale devices using graphene-based nano-antennas (" graphennas "), which operate in the Terahertz band. The strategies take into account the limitations of Terahertz channel and aim to optimize the overall network transmission rate of a network of nano-devices, while maximizing(More)
—As a step towards the realization of wireless nanosensor networks in agricultural monitoring applications, a theoretical path-loss model is proposed. This model can predict the average attenuation of THz radiation in a channel composed of air and plant leaves, given the composition of air as well as attributes of leaves such as their permitivity. In(More)
Graphene-based nano-antennas can enable wireless communications between nano-scale devices. Large numbers of nano-devices can be connected to form networks enabling a variety of applications, such as agricultural crop monitoring. Graphennas will resonate in the THz band, so high data rates are theoretically achievable. However, properties of THz(More)
— As the Packet/Cell Loss Ratio (PLR/CLR) is counted as one of the major Quality of Service (QoS) requirements; in this paper we proposed a linear upper bound expression for the loss probability approximation in high-speed communication network technologies. These technologies can support multiple classes of traffic with different QoS requirements and(More)
