More attention has been paid to congestion control in the emerging area of wireless sensor networks (WSNs). However, most of the existing congestion control schemes are based on the best-effort data transmission service model. When networks congestion occurs, different categories of traffic are discarded indiscriminately, therefore, users' Quality of Service (QoS) is not able to be guaranteed. In...
According to the power industry DL/T645 protocol and the characteristics of the meter data transmission, a wireless sensor network of automatic meter reading communications network is proposed. According to statistical feature of DL/T645 protocol and requirement of meter data transmission quality, an IEEE802.15.4 QoS (quality of service) communication network, is presented in this paper.
In order to realize the Smart Grid vision, it is necessary to have guaranteed Quality of Service (QoS) for the communication and networking technology used in various stages of the Smart Grid, ranging from power generation, transmission, distribution, to the customer applications. The low cost wireless protocols such as Zigbee (using IEEE 802.15.4 defined physical and MAC layer) and Bluetooth (IEEE802...
