| 摘 要： | 针对已有的三维无线传感器网络路由协议均将三维问题转换到二维平面上解决,没有充分利用三维空间的特点,提出了一种基于地理信息的三维无线传感器网络贪婪地理路由(GGR)协议。该协议在通常状况下采用贪婪转发算法,针对基于地理信息的贪婪算法中易出现的路由空洞问题,给出一种三维滚动球边界遍历算法。实验结果表明:该协议具有较高的路由成功率,路由跳数也得到优化,尤其是在节点密度较低的情况下体现出较强的优势。

| Abstract: | There are some drawbacks like transformation between different dimensions in existing routing protocols for 3D wireless sensor networks(3D WSNs).A greedy geographic routing(GGR)protocol for 3D WSNs is proposed.The protocol commonly uses greedy forwording(GF)algorithm to transfer the packet.At the same time,3D rolling ball traversal(3D-RBT)algorithm is employed to avoid routing void problem conduced by GGR algorithm.The experimental result shows a high routing success ratio and a satisfied routing hop number,especially when the node density is low. |
