RIS-assisted terahertz frequency band vehicle network capacity optimization by Fatang CHEN, Xiaoling LIU, Dan WANG, Ruofan ZHANG

“…In order to alleviate the spectrum scarcity and capacity limitation of the current wireless system, the terahertz frequency band was introduced and the reconfigurable intelligent surface (RIS) was used for auxiliary communication to construct a downlink vehicle network.Considering the constraints of limited total system power, QoS constraints of cellular mobile users, and randomness constraints of vehicle and user locations, a hybrid optimization model was established for optimal power allocation and optimal deployment of RIS with the aim of maximizing the total rate of vehicle users.Based on the balance method, linear transformation method, and element elimination method, the original NP-hard problem was transformed into a convex optimization problem with complex correlation constraints and multivariate coupling.The inner layer iteration was based on the Lagrange multiplier method to solve the optimal power allocation, and the outer layer iteratively solved the optimal deployment of RIS based on a improved genetic algorithm.The simulation results show that rationally deploying the number and distribution density of RIS nodes based on optimal power allocation can save costs while achieving a higher target total capacity.…”

False data filtering algorithm without relying on MAC authentication for wireless sensor networks by YI Ye-qing1, LIN Ya-ping1, PENG Ge1, ZHOU Si-wang2, YANG Si-qing1

“…A multiple semi-fragile watermarks algorithms was proposed,considering the characteristics of clustering col-laboration aggregation in WSN.The generation of watermarks,embeding and extraction were completed by not a single node,but a fixed number of witnesses nodes which selected within the same clusters.This algorithm could against leak-age of keys when a single node was captured,and it could save energy costs also.On this basis,a false data filtering al-gorithm was proposed based on multiple semi-fragile watermarks,this algorithm could authenticate the accuracy,com-pleteness and fresh using watermarks embedded in data,without relying on MAC authentication.It provided a compari-son between the scheme and previously proposed schemes.The analysis and simulation results indicate significant im-provement in probability of filtering false data,energy saving and having robust,yet fragile characteristics,which support lossy in-network data processing and resist of the noise in certain.…”
