Ubiquitous sensing allows smart cities to take control of many parameters (e.g., road traffic, air or noise pollution levels, etc.). An inexpensive Wireless Mesh Network can be used as an efficient way to transport sensed data. When that mesh is autonomously powered (e.g., solar powered), it constitutes an ideal portable network system which can be deployed when needed. Nevertheless, its power consumption must be restrained to extend its operational cycle and for preserving the environment. To this end, our strategy fosters wireless interface deactivation among nodes which do not participate in any route. As we show, this contributes to a significant power saving for the mesh. Furthermore, our strategy is wireless-friendly, meaning that it gives priority to deactivation of nodes receiving (and also causing) interferences from (to) the rest of the smart city. We also show that a routing protocol can adapt to this strategy in which certain nodes deactivate their own wireless interfaces.
无处不在的传感技术使智慧城市能够掌控许多参数（例如道路交通、空气或噪音污染水平等）。廉价的无线Mesh网络可作为传输传感数据的有效方式。当该Mesh网络采用自主供电（如太阳能供电）时，它构成了一个理想的便携式网络系统，可在需要时进行部署。然而，必须限制其功耗以延长其运行周期并保护环境。为此，我们的策略促进了不参与任何路由的节点之间的无线接口停用。如我们所示，这有助于Mesh网络显著节省电力。此外，我们的策略对无线友好，这意味着它优先停用那些受到（并对）智慧城市其他部分产生干扰的节点。我们还表明，路由协议可以适应这种某些节点停用自身无线接口的策略。
