摘    要:当前大多数传感器网络研究假设传感器节点在二维平面部署,然而许多水下传感器网络应用要求节点在三维空间分布。针对三维水下监视应用,提出一种新颖的分布式传感器网络拓扑生成算法(ETG)。基于格理论,ETG算法将节点的移动控制与活动设备的调度相结合。初始时刻监视设备密集部署在二维海平面上,ETG算法根据局部信息选择活动设备,并通过控制其传感器节点在垂直方向的移动,形成一个三维水下网络。仿真实验表明,ETG算法能够以较小的平均节点移动距离覆盖较大的空间,从而有效减少网络建立阶段的能量开销。

关 键 词:三维  水下传感器网络    拓扑生成

Abstract:Most current wireless sensor networks research assume that sensor nodes are deployed on a two-dimensional(2D)plane.However,a large number of underwater sensor network applications demand for a three-dimensional(3D) distribution of sensor nodes.A novel distributed topology generation algorithm(ETG) is proposed for 3D underwater surveillance sensor networks.Based on the lattice theory,ETG integrates the movement control of sensor nodes with a scheduling mechanism.Initially surveillance devices are densely deployed on the 2D sea surface.ETG selects active devices using only local information and controls the vertical movement of their sensor nodes to construct a 3D underwater network.Simulation results show that ETG can achieve larger coverage space at lower cost of average node movement distance,and thus effectively reduce the energy cost at the network set-up phase.
Keywords:three-dimensional  underwater sensor networks  lattice  topology generation
