An autonomous depth-adjustment deployment algorithm by growth ring for underwater wireless sensor networks

  • 摘要: 为提高水下无线传感器网络覆盖率,同时解决因通信能量消耗不均衡而造成网络无法正常使用的问题,本文提出一种“年轮式”水下无线传感器网络节点深度自部署算法.采取年轮式构建网络的以Sink节点为根节点的非均匀全连通树结构;在计算节点下潜深度时,构建基于覆盖利用率和能量均衡的优化模型,实现针对基准节点的全局最优深度计算.仿真实验结果表明,本文部署方法形成的网络拓扑结构,不但在确保全连通的前提下提升了网络覆盖率,而且有效均衡不同区域网络能耗,提高了后期使用网络的可靠性,有效延长了网络寿命.

     

    Abstract: In order to improve the coverage and reliability of UWSN under the condition of energy balance, an autonomous depth-adjustment deployment algorithm for sensor nodes of UWSN based on growing ring is proposed in this paper. A growth ring style-based scheme is adopted to construct the connective tree structure of sensor nodes. As for the depth-adjustment of nodes, a global optimal depth-adjustment algorithm with the goal of comprehensive optimization of both maximizing coverage utilization and energy balance is proposed. The experiments show that the proposed algorithm improves the reliability of UWSN under the condition of energy balance. Moreover, the algorithm in this paper improves the network coverage greatly while guaranteeing full connectivity.
