摘要
特种移动通信网与公用蜂窝移动通信网的重要差别在于:通信模式主要是采用非蜂窝的无线Ad Hoc;通信对象主要是物与物之间的通信(即传感器通信);通信拓扑主要是三维(3D)的立体拓扑,而不是传统的二维(2D)平面拓扑。拓扑控制(TC)是节能的无线Ad Hoc和无线传感器联网的关键技术之一。无线网络拓扑控制技术已进行了大量的研究,但是,大多数研究都是假设无线节点分布在一个二维平面(2D),如公用通信网。然而,实际上,特种通信网的无线节点通常部署在一个三维空间(3D),如多层建筑、空中、水下或地下。许多研究表明:当前的2D的拓扑控制算法不能直接用于3D网络,或者需要更复杂的计算才能用于3D网络。本文在分析了拓扑控制的动机、概念、分类技术及协议栈的基础上,陈述了研究最多的四种将2D拓扑扩展到3D的情况,讨论了用于3D网络的某些拓扑控制协议,也证明了某些特性。
The importance difference between Particular Mobile Communication Network and Common Cellular Mobile Communication Network lies in the following aspects:the communication mode mainly adopts non-cellular wireless Ad Hoc and the communication object is mainly communication between objects(namely Sensor Communication)and communication topology is mainly three-dimensional(3D)stereo topology,rather than traditional two-dimensional(2D)planer topology.The topology control is one of the energy-efficient wireless Ad-Hoc and wireless sensor networking key techniques.The topology control technique has been heavily studied in wireless networks,but most of these studies assume that wireless nodes are distributed in a 2 dimensional(2D)plane,such as Common Communication Networks.In practice,however,wireless nodes of Particular Communication Networks are often deployed in a 3-dimensional(3D)space,such as multi-floor building,space,underwater,or underground.Many studies showed that current 2D topology control algorithms are not able or require complex computations to apply in 3D networks.Based on the analysis of the motives of the topology control,the concept,classification technique,and the protocol stack,presented the most studied four kind will be extended from 2D to 3D topology case,and discussed certain of the topology control protocols for 3D network,and also proved several properties in this paper.
