Due to the advantages of muti-hop communication, self-organizing, self-healing and reliability, wireless muti-hop mesh network becomes an ideal solution for smart grid meter data collection. However, wireless muti-hop meter data collection network faces limitation and challenge on communication performance of network caused by application layer data traffic(More)
Because of the advantages of multi-hop communication, self-organizing, self-healing and reliability, wireless mesh network becomes an ideal choice for data collection. However, wireless mesh network for data collection faces challenge on communication performance of network caused by application layer data traffic. When a large number of data occurs in(More)
—Smart grid distribution and consumption communication network is one important part of smart gird communication network and the crucial technology field of smart grid. Smart grid distribution and consumption communication network due to its existing features such as large coverage, enormous number and irregular distribution of the network nodes and(More)
The knowledge embedded in data stream has the property of decaying with time, so people are more interested in the new data stream. This paper proposes a method for mining the frequent closed patterns in a sliding window to capture information timely and accurately when new data stream arrives. Data stream is divided into several basic windows. All possible(More)
One of the key technologies of smart grid is an efficient, reliable and secure two-way communication system for meter data collection. Because of the advantages of muti-hop communication, self-organizing, self-healing and reliability, wireless muti-hop communication technology becomes an ideal choice for smart grid meter data collection. However, forming(More)
Data collection communications system for electric power communication network is an important entity network in electric power system. It's significant to provide a reasonable routing mechanism for data collection system. The major risk of original routing mechanism is the burst congestion. In the data collection network of smart grid, that some nodes may(More)
