    The Influence of Coupling Coil on the Transmission Efficiency in Wireless Transmission System by SUN Zi-han, CHEN Shi-yu

    Published 2022-02-01
    “…In order to study the influence of the coupling coils on the transmission efficiency in wireless power transmission system with low-frequency excitation source, the dual software co-simulation method is used to analyze the magnetic field distribution under different placement modes of the electromagnetic coupling coil, and the relationship between the system efficiency and the excitation source waveform and the position of electromagnetic coupling coil is also given.The results show that no matter how the relative positions of the coils are distributed, the system transmission efficiency of the sine wave and triangle wave excitation sources has a small relationship with the coil position arrangement, the transmission efficiency of the two is similar, and the system transmission efficiency under the square wave excitation source is the lowest.Finally, using the lithium battery PNGV model as the system load, the system efficiency and time-varying waveforms are presented, so that the system charging process is closer to the actual charging situation.…”

    CT-TDMA:efficient TDMA protocol for underwater sensor networks by Lu HONG, Feng HONG, Zheng-bao LI, Zhong-wen GUO

    Published 2012-02-01
    “…Aimed at underwater acoustic sensor networks(UWSN),a novel sender based conflict model with the schemes of allocating continuous time was presented,including local conflict graph(LCG)and a distribute algorithm to generate LCG.Moreover,CT-TDMA,an efficient TDMA protocol based on the conflict model was also proposed,which used heuristic priority rules to allocate transmitting moments for all nodes.CT-TDMA exploits the diversity of propagation delay of different links in UWSN to decrease the idle time between packets at the same receiving node,which helps in improving the throughput.And a heuristic schedule algorithm is applied to shorten the process of allocating continuous time for each node.Simulation results show that,compared with traditional TDMA protocols such as ST-MAC,network throughput of CT-TDMA has increased 20% and end to end delay has decreased 18%;compared to the theoretically optimal scheme with global knowledge,CT-TDMA has achieved 80% network throughput and the end to end delay is only 12% longer.…”
