主　　题：Wireless computing power network blockchain digital twin placement minimum synchronization latency 

摘      要：As an open network architecture,Wireless Computing PowerNetworks(WCPN)pose newchallenges for achieving efficient and secure resource management in networks,because of issues such as insecure communication channels and untrusted device ***,as a shared,immutable distributed ledger,provides a secure resource management solution for ***,integrating blockchain into WCPN faces challenges like device heterogeneity,monitoring communication states,and dynamic network *** Digital Twins(DT)can accurately maintain digital models of physical entities through real-time data updates and self-learning,enabling continuous optimization of WCPN,improving synchronization performance,ensuring real-time accuracy,and supporting smooth operation of WCPN *** this paper,we propose a DT for blockchain-empowered WCPN architecture that guarantees real-time data transmission between physical entities and digital *** adopt an enumeration-based optimal placement algorithm(EOPA)and an improved simulated annealing-based near-optimal placement algorithm(ISAPA)to achieve minimum average DT synchronization latency under the constraint of DT *** results show that the proposed solution in this paper outperforms benchmarks in terms of average synchronization latency.
