    Robust resource allocation algorithm for heterogeneous wireless networkwith SWIPT by Yongjun XU, Yuan HU, Guoquan LI, Jinzhao LIN, Qianbin CHEN

    Published 2019-07-01
    “…To improve energy efficiency and robustness of heterogeneous wireless networks with wireless information and power transfer,the robust joint transmit power and power splitting resource allocation problem was studied.Based on mini-max probability machine and Dinkelbach method,the original NP-hard problem was transformed into a solvable convex optimization form,meanwhile a distributed dual resource allocation algorithm was proposed.Additionally,both computational complexity and robust sensitivity were analyzed.Simulation results show that the proposed algorithm can guarantee the quality of service requirements of macro cellular users and femtocell users under channel uncertainties.…”

    Published 2018-09-01
    “…Aiming at the problems of low resource utilization rate,high energy consumption and poor user service quality in the existing virtualized Cloud Radio Access Network,an energy-aware virtualized resource allocation mechanism with hybrid energy supply was proposed.According to the energy sources and energy consumption of different network devices,energy arrival and energy consumption models were established.Furthermore,under the premise of guaranteeing the quality of user services,considering proportional fairness and energy consumption optimization,distributed algorithms based on asynchronous update were used to allocate resources and harvested energy for different types of virtual cloud radio access networks and user virtual base stations to effectively improve the energy efficiency of network.The simulation results show that the proposed resource allocation mechanism can reduce energy consumption while effectively reducing the latency and improving the throughput.…”

    Robust resource allocation algorithm for multicarrier NOMA security communication system by Yu ZHANG, Xiongwen ZHAO, Xiaoqing WANG, Suiyan GENG, Peng QIN, Zhenyu ZHOU

    Published 2022-03-01
    “…To improve the spectrum efficiency and enhance the information security of wireless network, a sum secrecy rate maximization-based robust resource allocation algorithm was proposed for a downlink multicarrier NOMA security communication system.Firstly, the artificial noise (AN) precoding vector was designed to be orthogonal to the legitimate channel, so that the legitimate transmission would not be affected by the AN.Then, considering the constraints of rate requirement of each user and the maximum transmit power of base station, a joint AN precoding, downlink data precoding and subcarrier allocation optimization problem was formulated under eavesdropping channel uncertainties.To solve that non-convex problem, it was decomposed into two joint optimization subproblems: precoding optimization and subcarrier allocation.The former was solved based on S-procedure and block coordinate descent (BCD) algorithm, the latter was solved by dynamic matching theory.Simulation results demonstrate that the proposed algorithm has good robustness and can effectively improve the sum secrecy rate.…”

    An Energy-Efficient Multi-User’s Resource Allocation Scheme by Zhao Wang, Youming Li, Ting Zou, Xiaoqing Liu, Bin Chen

    Published 2013-04-01
    “…In wireless environment,the increases in the number of users and the demand for a higher rate have triggered rapidly booming energy consumption at the base station.Therefore,energy efficient design in wireless network has become very essential.An energy efficient multi-user OFDM downlink resource allocation scheme was studied,using the distributed way.Firstly,according to user’s average channel gain and the minimum requirements of user’s bits,subcarriers were allocated,combined with the idea of proposed energy-efficient criterion.Then better channels were assigned to each user in accordance with each user’s allocated subcarrier numbers.Again each user’s average bits were assigned on the user’s allocated subcarriers and optimal adjustment using energy-efficient criterion had to be made to ensure the minimum power.The simulation results show that under the conditions of satisfying bit-error rate and transmission rate for users,the power can be reduced by 5~6 dB in the proposed algorithm,compared with the power in the static frequency division multiple access resource allocation.Furthermore,the power can be reduced by 2~4 dB,compared with the power in a existing classical distributed algorithm.…”

    Research on IoV resource allocation algorithm assisted by reconfigurable intelligent surface by Fatang CHEN, Ruofan ZHANG

    Published 2023-09-01
    “…In order to meet the higher requirements of vehicle communication quality and spectral efficiency, a IoV resource allocation algorithm assisted by reconfigurable intelligent surface (RIS) was proposed.The RIS reflection coefficient matrix, power allocation, and spectrum sharing schemes were combined to solve the problem of maximizing the total capacity of V2I link under the condition of ensuring the reliability of V2V link.As this problem was a non-convex optimization problem with highly coupled variables, it was difficult to solve it directly.Therefore, after introducing an analytic expression to approximate the interrupt probability of V2V link, the problem was decomposed into three sub-problems by using the block coordinate descent (BCD) method, and the sub-problems were solved by introducing auxiliary variables, successive convex approximation (SCA), Hungarian algorithm, etc., and then the approximate suboptimal solution of the problem was obtained.Simulation results show that the proposed algorithm has good convergence performance and can effectively improve the total capacity of V2I link.…”
