Taking a Look at the ZigBee Systems - 874 Words
Figure 1 23 shows the proposed network arrangement between the nodes and their associated roles within the ZigBee network. The roles within the network are in accordance with the functionalities and requirements of each type of device as specified by the ZigBee networking standard. The PC/base station has been appointed the role of coordinator since its functions include hosting the SLAM and GUI processes. Therefore the PC/base station is required to transmit GUI data commands and receive updated sensor data to and from both quadcopters. Furthermore as these processes are computationally intensive and require a lot of memory resource; the PC/ base station must be mains powered; reinforcing the requirement for it to be a coordinator. The quadcopters have been appointed the role of routers so that they are able to relay data intended for the coordinator between each other, if one of the quadcopters should fall beyond the range of the coordinator. This would not have been possible if th ey were appointed the role of end devices. The quadcopters will be battery powered although the ZigBee standard for routers recommend that they be mains powered. Nevertheless, this recommendation was made out of preventing different network segments from falling if power to the router is lost. However this is not applicable in terms of this project as the routers will not be connected to any other network segments. The routers will be performing under the CSMA/CA multiple access method in whichShow MoreRelatedZigbee Based Home Automation System7138 Words à |à 29 PagesIEEE Transactions on Consumer Electronics, Vol. 55, No. 2, MAY 2009 A ZigBee-Based Home Automation System Khusvinder Gill, Shuang-Hua Yang, Fang Yao, and Xin Lu Abstract ââ¬â In recent years, the home environment has seen a rapid introduction of network enabled digital technology.

The Internet of Things (IoT) is the network of the physical objects containing embedded systems which connects and communicate with each other internally or externally through sensors. According to David Ahrens, it is the ââ¬Å"network of interconnected sensor-equipped electronic devices that collect data, communicate with each other, and can be monitored or controlled remotely over the Internetâ⬠(Ahrens, 2014).
