Low Earth orbit (LEO) satellite networks have attracted extensive research due to their potential to provide high-qualityinternet access services. However, the existing TCP variants, which are designed for terrestrial networks, can hardly work in LEO satellite networks with characteristics such as error-prone, bandwidth variations, and link switching. To address these challenges, in this paper we present a new information-centric transport layer protocol LEOTP to guarantee reliable, high-throughput, and low-latency data transmission in LEO satellite networks. It leverages the idea of Information-Centric networking (ICN) with a Request-Response transmission model and in-network caching. The connectionless transmission paradigm in LEOTP makes it resilient to dynamic topology changes. The caches equipped in intermediate nodes help to recover packet loss while the hop-by-hop congestion control mechanism provides a fast reaction to time-varying network conditions. We evaluate the performance of LEOTP in emulated Starlink constellation, which shows that it increases the throughput by 8%-12% with 40%-60% delay reduction compared with the state-of-the-art TCP variants in the transcontinental data transmission.

Next-generation 5G networks are rapidly expanding to support the growing demand for efficient connectivity in internet of Things (IoT) and Machine-to-Machine (M2M) applications across various sectors (e.g., agriculture, automotive, healthcare, smart cities, and manufacturing). Industrial internet of Things (IIoT) promises to transform manufacturing through Digital Twins while Industry 4.0 advances digitalization with Cyber-Physical systems (CPS), machine learning, big data, and cloud computing. Hence, achieving Ultra-low latency (ULL) is crucial for applications like robotic control. Although 5G powered by Software-Defined networking (SDN) and network Function Virtualization (NFV) have improved the network capacity and reduced the ULL constraints, challenges persist due to wireless signal unpredictability. To address these issues, this research proposes leveraging in-network applications to the network edge to implement ULL solutions for industrial and Unmanned aerial vehicles (UAVs) applications. Furthermore, we propose the hardware-based P7 emulation environment to evaluate data plane applications' performance, feasibility, effectiveness, and impact.

The Industrial Edge Computing (IEC) network has recently received considerable attention, where industrial devices offload their computation-intensive and delay-sensitive tasks to servers located at the network edge. Task offloading scheduling is a fundamental problem in IEC networks to achieve satisfactory quality of service. Many prior efforts have been devoted to scheduling task offloading for networks with complete information, while the complete information is hard or even infeasible to acquire by the scheduler. Therefore, their performance degrades in IEC networks with incomplete information. Scheduling task offloading for IEC networks with incomplete information is urgent and presents great technical challenges. This paper proposes a group-centric task offloading framework tailored for IEC networks with incomplete information, and models the minimum delay scheduling problem as a Partially Observable Markov Decision Process. Then, the SGOS algorithm integrating the Long Short-Term Memory with Soft Actor-Critic networks in reinforcement learning is proposed to devise online task offloading schedules for IEC networks with incomplete information. Extensive experimental results verify that the SGOS algorithm can achieve the best performance compared with baseline schemes in terms of major metrics, including convergence, delay, and workload balance.

This study focuses on the dual-objective optimization problem of Sensor-Weapon-Target Assignment (SWTA), aiming to minimize the expected threat values of incoming targets during combat while considering the minimal consumption of resources for effective resource allocation. We propose an innovative solution based on the Hopfield neural network by transforming the optimization model of the problem and introducing the energy function of the Hopfield neural network, which linearly combines the two optimization objectives. The states of the neural network correspond to the final allocation matrix, and by randomly adjusting weights, the neural network can converge to different solutions, ultimately obtaining the Pareto front. We designed scenarios for both small and large-scale cases in various combat situations and compared this method with traditional algorithms GA and PSO. The comparison algorithms also use linearly weighted objectives to solve the Pareto front. Experimental results indicate that in most cases, the Hopfield neural network demonstrates superior performance, achieving high-quality solutions at a lower time cost. Compared to traditional GA and PSO algorithms, it exhibits outstanding effectiveness in solving the SWTA problem. This research provides an advanced and reliable approach for military combat decision-making and offers valuable insights for the future development of intelligent systems.

The advancement of agricultural technologies in Honduras is paramount to bolster productivity in the sector. Embracing cutting-edge solutions like internet of Things (IoT) and ESP32 microcontrollers holds the potential to elevate crop quality, foster innovation and competitiveness, slash production costs, and drive rural development. Leveraging sophisticated tools such as MATLAB enables farmers and agricultural experts to harness mathematical matrix analysis for informed decision-making based on real-time data from a network of wireless sensors integrated into this prototype. Accessible through the Blynk platform, this streamlined approach marks a significant stride towards harnessing advanced technologies to revolutionize agriculture and uplift the livelihoods of Honduran farmers. The integration of IoT and Precision Agriculture (PA) technologies is vital. A centralized online platform tailored for Honduran farmers allows seamless access to real-time data from wireless sensors, covering crucial factors like weather conditions and crop health. The prototype's sensing data on coffee cultivation yielded 1000 data entries, which were analyzed to demonstrate consistent alignment with crop growth-promoting variables. Air temperature consistently ranged between 20 degrees C and 24 degrees C, which is the ideal range for coffee plants. Air humidity remained between 70% and 80%, suitable for effective transpiration and nutrient uptake. While pH levels regularly dropped between a recommended range of 5 and 7, ensuring nutrient availability, soil moisture readings consistently ranged from 60% to 80%, supporting healthy root systems and enabling nutrient absorption. The analysis of over 1,000 data entries confirms the effectiveness of IoT and PA technologies in addressing Honduras' agricultural challenges. Correlation with MATLAB enhances data credibility, facilitating better decision-making for agricultural progress.
Modern cellular systems must accommodate millions of mobile devices, placing significant demands on network capacity and performance. The predominant technologies for internet connectivity are Wireless Fidelity (Wi-Fi...
