With the continuous development of Industrial In-ternet Things (IIoT), obstacle detection for automated guided vehicles (AGVs) has become an urgent problem to be solved. However, existing solutions face difficulties in employing limited computational resources AGVs simultaneously achieve rapid and precise detection. In order tackle this problem, paper introduces a semantic-driven cross-modal scheme that jointly utilizes semantic encoding real-time transmission enhances precision by exploring...

Integrating visual-haptic remote control is an important application direction in the Industrial Internet of Things (IIoT). Cross-modal communications are considered to be effective technology support this application. However, due limited bandwidth and competition between modalities, quality visual transmission end user's immersive experience cannot guaranteed practical scenarios. To overcome dilemma, paper proposes a super-resolution reconstruction strategy for cross-modal communications....

Currently, traffic trends to grow explosively under the scenarios of advanced wireless communication networks and diversified services. How design suitable model accurately efficiently predict has become a significant technical challenge. To get over this dilemma, paper proposes lightweight broad learning system (LBLS) for prediction. Specifically, LBLS firstly adopts restricted Boltzmann machine (RBM) perform feature extraction. Then, gated recurrent unit (G RU) is introduced into...

Accurate and efficient people counting is essential to improve energy efficiency, space utility, user comfort in smart buildings. However, existing schemes suffer from an inherent limitation that more or less intrusive imprecise. Here we report a lightweight multi-objective approach for estimating indoor counts. Specifically, arrange infrared array sensor at the entrance, extract spatial position of moving targets each frame, then judge entry exit sequence according target trajectories....
