mmWave radar based robust sign language recognition for the smart museum by Xuerong ZHAO, Xuan WANG, Tong LIU, Xia ZHENG, Yicheng JIANG

“…A smart museum is a new form of a museum, which uses devices or technologies including the Internet of things (IoT) and artificial intelligence (AI) to build the information interaction channels between people, things, and space.Sign language recognition not only assists the visitors who have hearing or speech impairment to visit the museum without barriers but also helps study the visitors’ natural gesture interaction.However, the methods based on cameras and wearable devices mayhave issues like privacy or usability when applied to museum spaces.Therefore, a robust sign language recognition method based on millimeter-wave radar was proposed.Different features of distance and velocity changes relative to the radar device were firstly extracted in this method, then a physical data enhancement method was adopted to expand the training data.Finally, a ResNet based on the pre-processed distance time features and Doppler time features was designed to further remove the environment-related information and perform feature fusion for classification.Experimental results show that this method can effectively recognize sign language and achieve an averaged recognition accuracy of over 90% when the testing environment and the user＇s location change, providing a new method for smart museum wireless sign language and gesture recognition.…”

Context-aware learning-based access control method for power IoT by Zhenyu ZHOU, Zehan JIA, Haijun LIAO, Xiongwen ZHAO, Lei ZHANG

“…In view of the problems of severe access conflicts, high queue backlog, and low energy efficiency in the massive terminal access scenario of the power Internet of things (power IoT) in 6G era, a context-aware learning-based access control (CLAC) algorithm was proposed.The proposed algorithm was based on reinforcement learning and fast uplink grant technology, considering active state and dormant state of terminals, and the optimization objective was to maximize the total network energy efficiency under the long-term constraint of terminal access service quality requirements.Lyapunov optimization was used to decouple the long-term optimization objective and constraint, and the long-term optimization problem was transformed into a series of single time-slot independent deterministic sub-problems, which could be solved by the terminal state-aware upper confidence bound algorithm.The simulation results show that CLAC can improve the network energy efficiency while meeting the terminal access service quality requirements.Compared with the traditional fast uplink grant, CLAC can improve the average energy efficiency by 48.11%, increase the proportion of terminals meeting access service quality requirements by 54.95%, and reduce the average queue backlog by 83.83%.…”

UCAP:a PCL secure user authentication protocol in cloud computing by Xuefeng LI, Junwei ZHANG, Jianfeng MA

“…As the combine of cloud computing and Internet breeds many flexible IT services,cloud computing becomes more and more significant.In cloud computing,a user should be authenticated by a trusted third party or a certification authority before using cloud applications and services.Based on this,a protocol composition logic (PCL) secure user authentication protocol named UCAP for cloud computing was proposed.The protocol used a symmetric encryption symmetric encryption based on a trusted third party to achieve the authentication and confidentiality of the protocol session,which comprised the initial authentication phase and the re-authentication phase.In the initial authentication phase,the trusted third party generated a root communication session key.In the re-authentication phase,communication users negotiated a sub session key without the trusted third party.To verify the security properties of the protocol,a sequential compositional proof method was used under the protocol composition logic model.Compared with certain related works,the proposed protocol satisfies the PCL security.The performance of the initial authentication phase in the proposed scheme is slightly better than that of the existing schemes,while the performance of the re-authentication phase is better than that of other protocols due to the absence of the trusted third party.Through the analysis results,the proposed protocol is suitable for the mutual authentication in cloud computing.…”

MRR scheduling based cognitive LTE-R eNode B and type of service value priority queue management strategy by Hongyu DENG, Yiming WANG, Cheng WU

“…Cognitive radio technology was used to build cognitive radio networks in long-term evolution railway communication systems,and cognitive base station network architecture and MRR scheduling algorithms were proposed to improve the spectrum utilization of railway dedicated networks.In particular,the FIFO policy for cognitive LTE-R base stations in a single vehicle gateway causes excessive delay in real-time services of secondary users,and a cognitive LTE-R base station queue management strategy based on priority of service types was proposed.This strategy gave priority to sending packets with large service type values to the queue,so as to achieve the purpose of prioritizing real-time services.Simulation results show that under the premise of ensuring the normal communication of vehicles,the constructed cognitive base station can provide passengers with additional internet access links,and at the same time,improve the spectrum utilization rate of the LTE-R communication system.In addition,the cognitive base station queue management strategy based on service type value priority can effectively reduce the delay of passenger real-time services.…”

AODV protocol for acoustic-radio integrated network based on location information and energy balance by Nongyu WEI, Zilong JIANG, Fangjiong CHEN

“…Different from terrestrial internet of things (IoT) applications, marine IoT applications need to solve the problem of information interaction between surface network and underwater network.The key to solve this problem is to design a proper routing scheme.An ad hoc on-demand distance vector for acoustic-radio integrated network (AR-AODV) was proposed based on location information and energy balance.The protocol enables surface radio links to forward more information data, so as to reduce the burden of underwater communication network and improve the overall performance.In the proposed protocol, the forwarding priority of the buoy nodes was higher than that of the underwater nodes.When the source node needs to send data, it enters the route discovery phase, i.e., the node uses its position and energy information as the heuristic information to calculate the forwarding probability and broadcast route request (RREQ) packets.When the destination node receives an RREQ packet, it sent an RREP packet to update the pheromone and select the optimal path based on the pheromone.Compared with AODV protocol, AR-AODV protocol has significantly improved the performance in terms of transmission success rate, transmission delay, throughput, energy conversion rate and routing packet forwarding times.…”
