Design of embedded zigbee machine to machine smart street lighting system

摘要

Energy monitoring and controlling systems of smart street lighting system were highly dependent on the gateway in order to perform the communication between sensors and actuators to the users. M2M technology allows the process of device control more effectively because it is not centered on the Gateway but on the devices to device related. Congestion, delays and communication errors to be a challenge in the development of M2M technology. This research proposed M2M technology to make direct communication between devices and users with less congestion, delays and communication errors. The design of embedded zigbee using M2M technology was developed as dimmer control for LED lights and communication between devices. Furthermore, zigbee communication performance have been evaluated using received signal strength (RSSI) and network throughput. The ideal distance between zigbee in barrier area is approximately 30m and -83 dBm of RSSI. In loss area is approximately 65m and -80 dBm of RSSI. Performance of zigbee device communications shows the use of direct configuration is better than using a router. So that, on configuration via router, the number of transmitting nodes should be minimized.
