Our recent paper accepted to the IEEE ICASSP 2024 is now available on IEEE Xplore: https://lnkd.in/dzSKQq7g In this paper we present a novel self-supervised path-planning method for UAV-aided networks. First, we employed an optimizer to solve training examples offline and then used the resulting solutions as demonstrations from which the UAV can learn the world model to understand the environment and implicitly discover the optimizer’s policy. UAV equipped with the world model can make real-time autonomous decisions and engage in online planning using active inference. During planning, UAV can score different policies based on the expected surprise, allowing it to choose among alternative futures. Additionally, UAV can anticipate the outcomes of its actions using the world model and assess the expected surprise in a self-supervised manner. Our method enables quicker adaptation to new situations and better performance than traditional RL, leading to broader generalizability.

Happy to share our latest article on "Urban Air Mobility Communication Performance Considering Co-Channel Interference," published by the IEEE Transactions on Aerospace & Electronic Systems. Urban Air Mobility (UAM) involves small, highly automated aircraft carrying passengers or cargo at low altitudes in urban and suburban areas. This new mode of transportation aims to address some of the most important limitations of current road-based systems, including congestion, pollution and inadequate connectivity, significantly impacting the sustainable development of our cities. Our article delves into the challenges faced by UAM communication systems, focusing on co-channel interference and the potential of cellular networks to support low-altitude air transport operations. We present innovative interference mitigation techniques and an algorithm designed to improve the reliability of wireless communications, paving the way for safe and efficient UAM operations.

This paper considers a multi-#unmanned #aerial #vehicle (#UAV) assisted network in which multiple UAVs and a terrestrial base station (BS) are deployed to provide #mobile #edge #computing (#MEC) services to mobile users. The objective is to minimize an energy and latency-based cost function by jointly optimizing task offloading and MEC server selection decision, transmission power, UAV trajectory, and CPU frequency allocation. An alternating iterative approach based on the block descent method is proposed to solve this problem. In the first layer, task offloading and server selection decision subproblem is solved using a game theoretic approach. The second layer handles offloading and downloading transmission power allocations by utilizing a simplistic #geometric #waterfilling (#GWF) technique, and the UAV trajectory by #successive# convex #approximation (#SCA). Whereas, the third layer solves the computation resource subproblem by performing CPU frequency allocation using a gradient descent method. The proposed method uses a segment-by-segment approach, which divides the entire UAV flight trajectory into shorter timeframe segments to reduce the computation time. ---- Farhan Pervez, Ajmery Sultana, Cungang Yang, Lian Zhao More details can be found at this link: https://lnkd.in/eepwzgmA

Radio connections for uncrewed systems are going through significant changes. ➡️Cognitive radio is increasingly being adopted, using software-defined radio to analyse the local spectrum and find areas that are clear, reducing the power required and extending battery life. ➡️Mobile ad-hoc networks are being used with swarms of UAVs to enhance radio connectivity, sharing data about the spectrum across a wide area. ➡️New, lightweight antenna designs with multiple feeds and beamforming are also improving the performance of radio links in the air, allowing for longer range connections beyond the visual line-of-sight or reducing the power needed for close work. ➡️Meanwhile, machine learning and artificial intelligence are being adopted in radio systems to boost cognitive architectures and the efficiency of connections, especially for high-bandwidth video. ➡️At the same time, millimetre-wave radio technology (mmWave) is maturing to provide higher-bandwidth video links that are less susceptible to interference. The technology is maturing to be cost effective for vehicles on the ground and for high-altitude pseudo satellites, where power is a critical consideration.
