We study and solve a particular stochastic version of the Restricted Shortest Path Problem, the Stochastic Shortest Path Problem with Delay Excess Penalty. While arc costs are kept deterministic, arc delays are assumed to be normally distributed and a penalty per time unit occurs whenever the given delay constraint is not satisfied. The objective is to minimize the sum of path cost and total de...

Abstract A cost-effective millimeter-wave measurement setup for narrowband path loss and angle-of-arrival measurements is presented in this paper. The consists of ubiquitous radio-frequency lab equipment additional low-cost components. An algorithm developed, which improves the accuracy reduces required time. uncertainty analysis performed, including a noise analysis, amplifier linearity, anten...

Our long-term research goal is to model the in vivo wireless channel. As a first step towards this goal, in this paper we performed in vivo path loss measurements at 2.4GHz and make a comparison with free space path loss. We calculate the path loss by using the electric field radiated by a Hertzian-Dipole located inside the abdominal cavity. The simulations quantify and confirm that the path lo...

This paper applies a deep learning approach to model the mechanism of path loss based on profile in urban propagation environments for 5G cellular communication systems. The proposed method combines log-distance line-of-sight scenarios and deep-learning-based non-line-of-sight cases. Simulation results show that outperforms conventional models when operating 3.5 GHz frequency band. standard dev...

This paper performs site specific measurements which is essential for path loss prediction. The paper studies path loss and derive a statistical path loss model for deployed WiMAX network operating at a frequency of 2.3 GHz over a range of 100m to 3km. This work offers propagation measurements in a frequency range that is globally being allocated for broadband wireless systems. Keywords—Path lo...

Path gain and effective directional in azimuth urban canyons from actual rooftop base station sites are characterized based on a massive data set of 3000 links 12 streets two cities, with over 21 million individual continuous wave power measurements at 28 GHz using vertically polarized antennas. Large street-to-street path variation is found, median street varying 30 dB similar distances. Cover...
