Background & Objective: In this work, ahydrostatic pressure sensor based on a cavity coupled to a photonic crystal waveguide is proposed. A defect is introducedto createa sharp resonance in the structure which makes it useful for detecting pressure changes. The sensing principle is based on the shift of the resonant wavelength with the change refractive index which arises due to the hydrostatic pressure effect. The proposed Read More

Background & Objective: In the design of ad-hoc networks, potential challenge is how to route information reliably and efficiently from one node to another in high level of mobility. Moreover, remaining queuing capacity is also affected on the packet loss. Much research efforts have been consistently done to create protocols that consider minimum bandwidth, better throughput and less average delay. It is widely accepted Read More

Background & Objective: In this paper, we convert the problem of joint mode selection and resource allocation in in-band underlay device-to-device (D2D) communications into two subproblems. First, by using the closed-form expressions for the outage probability of both single-cell direct and relay-aided D2D communications in Rayleigh fading channel, a distance-based procedure is derived which introduces proper mode. For t Read More

Background & Objective: This paper proposes a modified eigenvalue-based Generalized Likelihood Ratio Test (GLRT). The proposed model is appropriate for cognitive wireless radio system under colored noise and unknown primary user's power. Herein, we introduce an optimization problem, which maximizes the detection probability under the constraints of false alarm, sensing time, the weighting of eigenvalues, an Read More
