    Link-disjoint routing algorithm under multiple additive QoS constraints by XIONG Ke1, QIU Zheng-ding1, ZHANG Yu1, ZHANG Hong-ke3

    Published 2010-01-01
    “…The problem of finding link-disjoint paths under multiple additive QoS constraints was studied.Since the existing algorithms depended on network’s structure and could not guarantee to find feasible solutions for arbitrary net-works,a novel algorithm called multiple constrained link-disjoint path routing algorithm(MCLPRA) was proposed.MCLPRA was based on SAMCRA and didn’t rely on the network’s structure.By introducing the parameter to control its search depth,dividing the solution space into different classes and performing searching according to the classes respectively,MCLPRA was able to obtain the feasible solutions for arbitrary networks.Theoretic analysis shows that MCLPRA can get the feasible and optimal solutions when traditional schemes can not.Comprehensive simulations also show that MCLPRA has better performances than existing algorithms in terms of higher average successful rate of getting feasible solutions with shorter average total length of the obtained path pair.…”

    Novel non-cooperative power control game algorithm for cognitive radio by Jun-hui ZHAO, Tao YANG, Xue-xue ZHANG

    Published 2012-11-01
    “…A novel non-cooperative power control algorithm based on new pricing function and the characteristics of cognitive radio technology was proposed with the interference temperature constrain,in order to improve signal to interference plus noise ratio of CR.The problem of power control was changed into the problem of multi-restraints non-linear optimization with interference limits based on channel conditions,maximal network and power limits.The existence and unique of nash equilibrium(NE)in utility function by the principle of game theory and optimization were proved and a distributed algorithm for this game was proposed.Simulation results show that the proposed algorithm can improve users QoS(quality of serves),system performance effectively and improve radio resource efficiency.…”

    Topology Control Algorithm in Heterogeneous Wireless Sensor Network with Energy Supply by Chenming Ma, Wanliang Wang, Zhen Hong, Xinwei Yao

    Published 2015-08-01
    “…In view of the problem that current algorithm mainly research on topology construction or topology maintenance separately,a topology control algorithm based on two processes combined was proposed,which was adaptive to the network with heterogeneous communication and energy.Topology construction was to construct connected dominating set with low message overhead,and topology maintenance was to execute local or global repair strategies by sink node based on time,energy or failure mechanism to save energy.Theoretical analysis and simulation experiments confirm that the algorithm can construct topology with low time and message overhead and extend network lifetime.…”
