无线MESH网络拓扑控制研究

作为下一代无线网络中的一种新型网络结构,无线MESH网受到了广泛关注。MESH网络节点间的自组织组网方式,使得网络具有良好的灵活性、鲁棒性,同时也使得MESH网络的性能称为研究的重点。从功率控制和信道分配等方面研究了MESH网络的虚拟骨干结构的拓扑优化,功率控制通过调节节点发射功率来改变其对邻居节点的影响;信道分配利用正交信道的相互不连通性质改变节点对于邻居节点的影响,以降低链路间的干扰、维护网络连通性、提高系统容量。

Study on Topology Control in Wireless MESH Network

Wireless MESH network,as the next generation wireless network,has attracted much attention today.MESH network may be seen as WLAN and its APs are connected by wireless.MESH network structure is different from both IEEE802.11 WLAN and ad hoc.However,the achieved results from 802.11 and ad hoc could assist the research on MESH network.This paper focuses on the improvement of network throughput,lowering of interference and maintenance of network connectivity by multi-radio multi-channel technique and power con...
