Adaptive resource optimization mechanism for blockchain sharding in digital twin edge network by Li JIANG, Shengli XIE, Hui TIAN

“…To address the security and privacy issues for data sharing in digital twin edge networks, a new distributed and secure data sharing mechanism was developed by leveraging blockchain sharding.Considering dynamic and time varying features in digital twin edge networks and mapping errors of physic networks, an adaptive resource allocation model was formulated which jointly optimized cluster head selection, local base station (BS) consensus access selection, spectrum and computation consensus resources allocation, in order to maximize transactional throughput for the blockchain sharding.Moreover, a digital twin edge networks empowered two-layered proximal policy optimization (PPO) algorithm was designed to obtain the optimal solutions.Numerical results illustrate that the proposed algorithm can effectively improve the transactional throughput for the blockchain sharding.Meanwhile, it can well adapt to the mapping errors.…”

Research on trust sensing based secure routing mechanism for wireless sensor network by Dan-yang QIN, Shuang JIA, Song-xiang YANG, Jing-ya MA, Yan ZHANG, Qun DING

“…Aiming at the serious impact of the typical network attacks caused by the limited energy and the poor deployment environment of wireless sensor network (WSN) on data transmission,a trust sensing based secure routing mechanism (TSSRM) with the lightweight characteristics and the ability to resist many common attacks simultaneously was proposed.Based on the analysis of the characteristics of network attack,the trust degree calculation model was constructed by combining node’s behavior with energy,at the same time the security route selection algorithm was also optimized by taking trust degree and QoS metrics into account.Performance analysis and simulation results show that TSSRM can improve the security and effectiveness of WSN.…”
