论文摘要
如今，几乎所有WiFi网络都为连接的移动节点提供了单个频段（2.4 GHz或5.8 GHz）无线通信功能。在单个频段网络中，干扰取决于网络中的节点数量以及接近度中其他网络的存在。随着网络中的节点数量的增加，网络中的干扰也增加了网络的吞吐量。如果有两个单个频段网络，一个在2.4 GHz频带中工作，另一个在5.8 GHz频段中工作，则网络1中的节点不会引起网络2中的节点的任何干扰。这可以用作实现网络的基本思想，以实现一个网络，其中同一网络中的节点同时使用频率频段来最大程度地减少节点之间的干扰。我们表明，与具有单频段的网络相比，构建双频段多跳线网络在吞吐量方面具有更好的性能。
Almost all the WiFi networks today provide single band (either 2.4 GHz or 5.8 GHz) wireless communication functionality for connected mobile nodes. In a single band network, the interference depends on number of nodes in the network and the presence of other networks in the proximity. As the number of nodes in a Network increases, the interference in the network also increases which reduces the throughput of the network. If there are two single band networks, one operating in 2.4 GHz frequency band and other in 5.8 GHz frequency band, then nodes in network 1 will not cause any interference with nodes in network 2. This can be used as a basic idea to implement a network where the nodes in the same network use both the frequency bands to minimize the interference between nodes. We show that building dual band multi-hop network gives better performance in terms of throughput compared to that of a network with single frequency band.
