A Method for Electric Load Data Verfication and Repair in home Environment (2016)
Presentation / Conference Contribution
Liu, Q., Li, S., Liu, X., & Linge, N. (2016, July). A Method for Electric Load Data Verfication and Repair in home Environment. Presented at the 2nd International Conference on Cloud Computing and Security

Most people do not have a consciousness of energy saving. For this phenomenon, the governments are building smart grids to take measures for the energy crisis. Electric load data records the electric consumption and plays an important role in operati... Read More about A Method for Electric Load Data Verfication and Repair in home Environment.

Grid Routing: An Energy-Efficient Routing Protocol for WSNs with Single Mobile Sink (2016)
Presentation / Conference Contribution
Liu, Q., Zhang, K., Liu, X., & Linge, N. (2016). Grid Routing: An Energy-Efficient Routing Protocol for WSNs with Single Mobile Sink. In Cloud Computing and Security (232-243). https://doi.org/10.1007/978-3-319-48674-1_21

In a traditional wireless sensor network with static sinks, sensor nodes close to the sink run out of their batteries quicker than other nodes due to the increased data traffic towards the sink. These nodes with huge data traffic are easy to become h... Read More about Grid Routing: An Energy-Efficient Routing Protocol for WSNs with Single Mobile Sink.
