In this study, we provide a novel approach to multicast wireless ad hoc network routing with cluster QoS optimization. The notion of topology compression is used to quantify the effect of multicast heterogeneity on scheduling by use of a compressed multiplex topology matrix. Topology matrices are defined by first identifying all feasible multicast pathways, including network-coded paths. In a conflict-free environment provided by careful scheduling, a selection of these pathways with optimal rates is selected to optimize feasible throughput and capacity per sum of transmission powers along the route. As a result, this optimization yields not one but two improvements: one in the form of performance enhancement due to planning on a condensed network topology, and another in the form of mixed route selection optimizations that strike a fine balance between multicast variety and network coding. As an example, we provide the numerical findings for a basic wireless butterfly network. If throughput is the only metric of importance, then either a network coded design or simple routing may be optimal, depending on the specifics of the system. However, a collection of simple routing pathways is optimal if throughput is prioritized above power consumption. In this study, we examine the problem of energy-efficient topology management in ad hoc wireless connections. We create an Energy Effective Topology controller method that incorporates a pertinent QoS Routing system in order to identify a network architecture that has maximum network lifespan fulfill QoS criteria, which includes traffic needs, hop bound, and bandwidth. The combined analytical along with numerical findings show that, when compared to algorithms that are solely concerned with reducing energy consumption, this optimal method can achieve the optimum network lifespan, which is a genuine period of time and more important and reasonable than merely reducing energy consumption. © 2023 IEEE.

Congestion is the main reason why connections fail when there are too many people on the network. This leads to the loss of nodes and modify the way setup of Mobile Ad-hoc Network (MANET). As we know, MANET is a network with no permanent infrastructure. It is made up of a temporary network that doesn't need a central manager or the usual support equipment found in traditional networks. To assure the longevity of MANET, networks can be constructed anywhere. Buffer overflow and congested links are caused by severe network demand, resulting in significant packet loss. Proper routing results in packet delays and has an effect on the MANET protocol's packet delivery rate. Machine learning (ML) is a part of Artificial Intelligence (AI) which is able to improve the QoS of routing in networks. In this paper, we discuss the latest research work to learn some innovative concepts and focus on doing something new in the field of Machine Learning in MANET. A well-balanced strategy is a method for avoiding network congestion. Load balancing allows network consumption to be optimized, packet latency to be reduced, and packet distribution ratio to be enhanced. Shifting loads from congested to less congested paths enhance the network's overall efficiency. MANET routing protocols prefer paths with less hops and exclude paths with more hops, but in extreme load conditions, they prefer paths with less hops. Furthermore, we investigate congestion management routing options in order to suggest a new approach in the future for identifying and preventing congestion risk in MANET. © 2023 IEEE.

The by-product gas is an important secondary energy in the iron and steel industry. It is important to make the by-product gas's utilization efficient and reasonable,which is the key to improve the economic efficiency and the level of energy conservation and emission reduction. Aiming at the problems of complex dynamic changes, difficult to accurately model and difficult to predict real-time traffic in gas energy system, this paper proposes an optimal scheduling method based on meta-learning multi-objective particle swarm optimization algorithm. The gas energy optimization scheduling problem is modeled as a multi-objective dynamic scheduling optimization problem. The difficulty of this problem is to comprehensively consider multiple indicators, continuously adapt to the change of the objective function over time, and track the changing Pareto optimal solution set. One of the promising solutions is to build prediction models with better performance under dynamic changes. The model we propose makes full use of the optimization results and the experience information of the optimization process in the historical optimization task. We propose a dynamic parameter initialization method based on meta-learning by starting multiple historical optimization tasks at the same time. Thus,the comprehensive parameters of different tasks are obtained, and a general and best base parameter is learned. Experiments show that the proposed model has better convergence and accuracy than the conventional algorithm. (c) 2023 Published by Elsevier Ltd.

Based on topology optimization, a lightweight design for an intelligent transport robot's front claw, capable of automatic opening, closing, and slight deflection, was developed. The front claw was 3D printed using a 40% fill rate and polyester resin material, addressing the issues of the robot's slippage and line-tracking speed. ANSYS analysis was used to study the stiffness of the front claw, examining the deformation amount and positions in the Y and Z directions, and overall deformation for the front claws and support connecting rods made from ABS and polyester resin in both open and closed states. The deformation amounts in the Z direction and overall, with and without gravity, were compared, validating the stability and effectiveness of the front claw driven by rack and pinion engagement under various conditions, and confirming that the ABS connecting rod deformation meets the requirements for sensor functionality. The motor and servo linkage achieved motion control of the front claw. Through multiple tests, including opening claw backward rotation, slight deflection during opening and closing, stable line-tracking with an open claw, and black frame stability tests, it was repeatedly verified that the front claw of the intelligent transport robot meets the enterprise requirements for transporting a Rubik's cube from any position to the target area. © 2024 SPIE.

This paper concerns the leaderless fixed-time consensus (LL FTC) problems for multi-agent systems (MASs) via event-triggered impulsive control, where the impulsive control time sequence is produced by event triggered mechanism. Both continuous control and periodic event-triggered control (ETC) are generated by continuous measuring and periodic sampling, respectively. To reach consensus for MASs, a brand-new fixed-time event-triggered impulsive control strategy is suggested that can significantly quicken convergence, obtain the lower energy consumption and decrease the update times of the controller. Then, a sufficient condition is presented to realize the LLFTC of MASs. Moreover, continuous communication and Zeno behavior are prevented by the suggested control protocol, which has been demonstrated. Finally, to show the event-triggered impulsive controller’s effectiveness, one numerical simulation is offered. It can be seen that the measurement error converges to zero in 1.8 s, the leaderless example can achieve consensus in 0.8–1 s. And the lower bound for the event interval time is 0.02 s, the maximum bound for the event interval time is 0.2 s,which means the ETC via impulsive control strategy obviously speed up controller update times. © Beijing HIWING Scientific and Technological Information Institute 2024.

To solve the problem of intercepting target with missiles for forward tracking, this paper proposes a novel forward tracking guidance algorithm based on adaptive fast dynamic surface sliding mode control method for interceptor missiles. Firstly, the guidance system model of forward tracking intercept is established based on the relative motion relation of missile-Target and forward tracking interception principle. Secondly, in order to deal with the uncertain interference in the system and improve the guidance accuracy, the variable gain extended state observer (TVGESO) is used to estimate the interference in the model, on this basis, the forward interception guidance law is designed based on interference estimation and adaptive fast dynamic surface sliding mode control method. Finally, the simulation results verify that the proposed forward tracking guidance law based on the adaptive fast dynamic surface sliding mode can intercept the target in front of the target and has better guidance accuracy. © 2023 SPIE.

Iterative optimization of signal control timing is an significant way to alleviate urban traffic congestion. In order to ensure the stability of traffic operation under traffic congestion, this paper constructed a coordinated control algorithm for congestion sub-area facing queue suppression. By introducing path traffic flow and path length indicators, a method for selecting critical traffic paths under congestion conditions was proposed. A coordinated control model for congestion sub-area was established, with the optimization goal of maximizing the throughout traffic volume of critical traffic paths and minimizing the increment of maximum queue length in sub-area. In order to improve the convergence ability of the algorithm, taking the green signal ratio, phase sequence, split and cycle as optimization parameters, a microscopic simulation environment was constructed to solve individual fitness, and an improved adaptive genetic algorithm based on simulated annealing adaptive crossover and mutation strategy was used to obtain optimal signal timing parameters. The simulation results showed the proposed method can effectively improve the sub-area traffic operation efficiency under congestion conditions.

Flexible sensing film has a broad application prospect in the fields of medicine, wearable electronic devices, complex environment sensing, and others. In this paper, dimethylsiloxane (PDMS) was used as a flexible substrate to prepare composite conductive films by covering silver nanowires (AgNWs) with specific lines on the substrate surface. The resistance change of the sensor is mainly caused by the change in the number of contact points between AgNWs on the film surface, which has higher linearity than the traditional resistance strain gauge. The sensor is very sensitive and has a very good measuring effect on the pressure of 0-6N and the micro-bending caused by 0-1N. Common sensors made of micro-nano materials are usually affected by transverse strain. The sensor in this experiment designs a special circuit structure, which can effectively avoid the lateral effect. The sensor also has the characteristic of self-recovery, which can achieve self-recovery under a certain degree of damage. It can be used to detect small changes in the skin.
