提出了一种新的网络拓扑结构--部分单位Delaunay图(PuDel),作为Ad hoc无线网络的底层网络拓扑结构。PuDel具有以下吸引人的性质:(1)PuDel是单位Delaunay三角剖分的连通子图;(2)PuDel是单位圆盘图(UDG)的平面扳手,其长度拉伸因子最大为1.21;(3)PuDel可以仅基于1跳邻居的位置信息本地构造,并且除了维护UDG之外,不需要节点之间的消息交换。
This paper proposes a new geometry structure, namely Partial unit Delaunay graph (PuDel), to be as the underlying network topology of Ad hoc wireless networks. PuDel has the following attractive properties: (1) PuDel is a connected subgraph of unit Delaunay triangulation; (2) PuDel is a planar spanner of Unit Disk Graph (UDG) whose length stretch factor is at most 1.21; and (3) PuDel can be locally constructed only based on the position information of 1-hops neighbors, and requires no message exchange between nodes in addition to maintaining UDG.
