Research Development of Topology Control Strategies for Wireless Ad Hoc Networks

拓扑控制是无线自组网中最重要的技术之一,主要用来降低能量消耗和无线干扰,其目标是在降低能量消耗和无线干扰的前提下,控制网络节点问的通信串路和节点的传输范围,以提高全网的生命周期和效率,如连通性和对称性等。本文首先介绍了拓扑控制模型;然后给出了拓扑控制策略的分类,回顾了无线自组网拓扑控制策略的研究进展,并对有关策略进行了分析;最后给出了该领域的一些研究方向。

Topology control is one of the most important technologies which are used in wireless Ad hoc networks to reduce energy consumption and radio interference. Its goal is to control the communication links between network nodes and transmitting range of the nodes in order to prolong the life cycle of the whole network and improve its network efficiency, such as connectivity, symmetry, while reducing energy consumption and radio interference which have a strict effect on the transmitting range of the nodes. Firstly, topology control models are introduced. Secondly, a taxonomy of topology control techniques is provided, the progress of the topology control technologies is surveyed, and various topology control strategies are described. Finally. several directions of further research are suggested.
