Energy-efficiency based buffer-aided relay selection scheme in SWIPT by Xinlong HONG, Xiaorong XU, Yingbiao YAO

“…Aiming at the problem of buffer-aided half-duplex (HD) relay selection in simultaneous wireless information and power transfer(SWIPT) with energy constraint,energy-efficiency priority based buffer-aided relay selection scheme in SWIPT was investigated.Moreover,SWIPT system energy efficiency was studied,and an appropriate mathematical model was constructed to perform energy efficiency based buffer-aided optimal receive/transmit relay selection in SWIPT.Numerical results show that the proposed scheme effectively reduces SWIPT outage probability and achieves the tradeoff between energy efficiency and outage performance in buffer-aided SWIPT.…”

Spectrum allocation of cognitive wireless network based on immune clone selection optimization by CHAI Zheng-yi1, LIU Fang1

“…The spectrum sensing process was described based on WRAN.By analyzing physical connection of cognitive wireless network,the mathematical model of spectrum allocation was given,and then it was converted into a constrained optimization problem,whose goal was to maximum the profit of network.An immune clone selection algorithm was proposed to solve the problem,and the algorithm convergent with probability 1 was proved.Finally,the simulation experiments were done to test the algorithm.The results showed that compared with CSGC algorithm（color-sensitive graph coloring） and GA-SA（spectrum allocation based on genetic algorithm）,this algorithm could achieve maximization of network profits.Meanwhile,the system simulation results based on WRAN confirmed its effectiveness.…”

Low failure recovery cost controller placement strategy in software defined networks by Qi WU, Hongchang CHEN

“…The controller placement is an important problem in software defined networks.Existing researches pay more attention to deploying controller planning for node failures and ignore the fact that the link failure can also effect the network drastically.To solve the problem,a mathematical model for the controller placement that plans ahead for the link failures to avoid a drastic increase failure recovery cost was proposed.To solve the model,an algorithm based on simulated annealing was designed.The simulation results show that the proposed model and algorithm can improve the robustness of the network.The maximum failure recovery cost is significantly reduced when a link falls in failures.…”
