    High performance full diversity LDPC codes construction and performance analysis for H-ARQ channels by Rui GUO, Fang-ning HU, Ji-lin LIU

    Published 2012-04-01
    “…In order to improve the performance of communication system with hybrid automatic repeat request(H-ARQ),a kind of full diversity low density parity check(LDPC)codes on H-ARQ block-fading channels was proposed.First,the outage probability and inherent diversity were analyzed,then a kind of full diversity PDPC codes for H-ARQ channel was designed.The new proposed LDPC codes connected the initial transmission with the repeated transmissions by root-connection to get extern diversity gain.In addition,the relationship between the structure of full diversity LDPC codes and the coding gain was given,and an algorithm to improve coding gain was brought forward by increasing the proportion of full diversity parity bits.Simulation results show that the proposed algorithm can not only achieve full diversity,but also get better performance than constructed LDPC codes at present.…”

    Data aggregation scheduling algorithm based on twice maximum independent set by Jian XU, Geng YANG, Zheng-yu CHEN, Hai-yong WANG, Zhen YANG

    Published 2014-01-01
    “…The main task in designing a data aggregation schedule was to get a good trade-off between QoS and weighted fairness guarantee.In order to address this problem,a novel data aggregation scheduling algorithm,MISS,was proposed,which could produce a collision-free TDMA schedule for data aggregation based on twice Maximum Independent Set (MIS).In the first phase,a tree structure based on MIS was constructed,and then it was adjusted according to the energy consumption forecast of each node,forming the balanced data aggregation tree.In the second phase,the approximate maximum weighted Independent set (WMIS) was utilized of all selected links to allocate time slots for each communication link.The results of simulation demonstrate that MISS not only improves the aggregation delay and lifetime of the network,but also gives weighted fairness guarantee.…”

    Published 2023-12-01
    “…A ZigBee network anonymous authentication scheme based on Chebyshev chaotic mapping and Chinese remainder theorem (CRT) was proposed to solve the problems such as the incomplete reliability of ZigBee network trust center and the lack of identity authentication when accessing the network.The proposed scheme can not only realize two-way authentication of anonymous identity, but also ensure the security of key distribution when ZigBee network structure changes dynamically.It is mainly based on a ZigBee and NB-IoT wireless heterogeneous gateway, so that the server can effectively manage the nodes in the network through this gateway.From security analysis and comparison with other related literature, the proposed scheme has higher security, with anonymity and unlink ability.In addition, the results show that the proposed scheme has more advantages than other schemes on the computational overhead.…”
