4. 3. Wireless Sensor Networks in Smart Cities : The Monitoring of Water Distribution Networks Case

   Författare :Du Rong; Carlo Fischione; Ming Xiao; Iordanis Koutsopoulos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Programming; Nonconvex Optimization; Network Lifetime; Dynamic; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The development of wireless sensor networks (WSNs) is making it possible to monitor our cities. Due to the small size of the sensor nodes, and their capabilities of transmitting data remotely, they can be deployed at locations that are not easy or impossible to access, such as the pipelines of water distribution networks (WDNs), which plays an important role in protecting environment and securing public health.
