Those functions should send data to terminal users, such as power meters, which is different from the old AMR systems. As the footstone of the Smart Grid, the new generation of AMR system in Smart Grid not only can collect the data of power meters remotely, but also can have functions of power rationing, multirate billing, remote on-off control, power line loss test, antistealing, and the monitoring and management of power line and meters. Although the focuses of their plans are different, the intellectualization of power utilization for terminal users is important work in most countries. Many countries have been carrying their own Smart Grid plan into reality. The simulation results show that the life cycle of network is extended.
We have also proposed a new routing algorithm called Energy Saving-Based Hybrid Wireless Mesh Protocol (E-HWMP) on the premise of current algorithm, which can improve the energy saving of the HWMP and be suitable for the WiFi-based wireless sensor network. In this paper, we have designed a new architecture of WiFi-based wireless sensor network, which is suitable for the next generation AMR system. With the development of the WiFi sensor node in the low power cost, a new kind of wireless sensor network based on the WiFi technology can be used in application. However, the traditional AMR network cannot meet the previous requirement.
The Automatic Meter Reading (AMR) network for the next generation Smart Grid is required to possess many essential functions, such as data reading and writing, intelligent power transmission, and line damage detection.
