    Optimization strategy on coverage control in wireless sensor network based on Voronoi by Chun-jiang ZHAO, Hua-rui WU, Qiang LIU, Li ZHU

    Published 2013-09-01
    “…Coverage holes directly reduce network performance and become a key problem of wireless sensor network.A detect-repair scheme for area coverage in wireless sensor network with Voronoi was proposed.The strategy achieves the network coverage rate optimization balance with a prerequisite of an acceptable coverage quality of network area.It uses the geometry theories and vector algebra to analyse the sensing range of nodes and the position feature of Voronoi polygon.It can calculate the accurate area of holes and ensure the connectivity of networks with the least number of odes.Simulation results show that the strategy can effectively reduce number of the nodes and the overlapped sensing regions and control redundant nodes.Meanwhile,the strategy has fast convergence speed.It not only realizes the control and optimization of the network coverage,but also outperforms existing algorithms with respect to the coverage of the target region.…”

    Holographic Carrollian currents for massless scattering by Romain Ruzziconi, Amartya Saha

    Published 2025-01-01
    “…We then construct Carrollian CFT currents from the ascendants of the hard graviton operator, which satisfy the Lw 1+∞ algebra. We show that the large-time limit of their Ward identities implies an infinite tower of projected soft graviton theorems in the bulk, while their finite-time OPEs encode the collinear limit of scattering amplitudes.…”
