    3D WSN clustering routing algorithm based on IHBA optimized fuzzy C-means by Jing YANG, Biyang XU, Weizheng LI, Wei LI, Zhaoqiang ZHU, Tao QIN

    Published 2023-12-01
    “…Aiming at the problem that clustering routing algorithm in a three-dimensional (3D) scene has high energy consumption and short network lifetime, a clustering routing algorithm IFCRA for 3D wireless sensor networks based on improved honey badger algorithm optimized fuzzy C-means was proposed.The network clustering, cluster head election, and data transmission stages were optimized respectively.Firstly, the improved honey badger algorithm was used to optimize the fuzzy C-means algorithm, solving the problem of fuzzy C-means easily falling into local optima, and the topological structure was divided based on the distance and energy characteristics of nodes.Secondly, the optimal cluster head function was constructed by combining the energy and relative distance of nodes within the cluster to balance the cluster head load.Finally, an adaptive transmission mechanism was used to search for relay nodes, and the optimal transmission path function was constructed by combining node distance and energy.The improved honey badger algorithm was used to optimize the data transmission energy consumption.Simulation results show that IFCRA has reasonable clustering, balanced energy consumption, and long lifespan in a 3D heterogeneous scene.…”

    Energy-Balanced Density Control to Avoid Energy Hole for Wireless Sensor Networks by Jie Jia, Jian Chen, Xingwei Wang, Linliang Zhao

    Published 2012-01-01
    “…Density control is of great relevance for wireless sensor networks monitoring hazardous applications where sensors are deployed with high density. Due to the multihop relay communication and many-to-one traffic characters in wireless sensor networks, the nodes closer to the sink tend to die faster, causing a bottleneck for improving the network lifetime. …”
