      Optimized query routing trees for wireless sensor networks 

      Andreou, Panayiotis G.; Zeinalipour-Yazdi, Constantinos D.; Pamboris, Andreas; Chrysanthis, Panos K.; Samaras, George S. (2011)
      In order to process continuous queries over Wireless Sensor Networks (WSNs), sensors are typically organized in a Query Routing Tree (denoted as T) that provides each sensor with a path over which query results can be ...
