Zigbee Network Performance Simulation For Smart Campus And Reliable Path To Improved

As IBM's "wisdom of the Earth" is classified as the national strategy of the United States, China's Premier Wen Jiabao visited in Wuxi, also proposed the "Experience China" ideology. "Internet of things", as the core of "Earth Wisdom" and "Experience China" has begun to flourish in the development of the world. "Smart Campus" as the applications of "Internet of Things" for school, leading the direction of construction and development of Smart Campus, including universities, secondary schools, primary schools. The application of "Experience the campus," will enhance the school's information, and management of efficient and lower cost of management, to provide strong technical support platform for campus.ZigBee, as a new wireless network technology of short-range, low rate, low-power, is very suitable as the wireless sensor networks (also known as WSN) of Smart Campus. Therefore, the research of how to use ZigBee to realize the target object of things-things internet for the applications of "Internet of Things" has a very important practical value. This paper aims to study how to better design ZigBee technology platform for smart campus, the implementation of performance evaluation on the platform, and the lack of implementation for the ZigBee feedback and improvement.This paper takes the needs of campus intellectualization construction application as the background. Under the utilization of the extremely popular network simulation technology nowadays in the world, we carry on the ZigBee performance test. We design different scenarios for Smart Campus applications in network simulation tools, and generate the simulation result by the Discrete Event Simulation (also known as DES) and virtualization technology. By analyzing the data of the report, ZigBee can not only achieve a steady rate and a lower delay in sending and receiving data by sensors, but also support self-healing mechanism, while providing supporting networking ability for fixed and removable ZigBee devices at the same time. In the simulation environment, we also compared the performance difference of campus-oriented, and analysis of the ZigBee routing nodes instability, leading to the changing topology of the impact on network performance and provides a reliable path-based routing algorithm to improve the performance of the ZigBee routing algorithm, by the backup path algorithm adapting to dynamic network topology changes, the network throughput and latency improved significantly. Finally, we prove in the ZigBee, compared to Wi-Fi and Bluetooth technology, more suitable for the application of Smart Campus.Internet of Things applications includes smart campus, smart home, intelligent energy, intelligent transportation, intelligent medical, and other fields. Represented as an intelligent campus, the paper described the ZigBee technology applications on campus. In order to achieve efficient school management, we have introduced the ZigBee Smart campus gateway. Through ZigBee gateway, both on the GSM mobile network can achieve the connection, but also by computer network access. Here we point out, ZigBee is not think the existing campus network construction as the overall repudiate, but in the basis of the existing network environment to provide more effective supplement for applications of smart campus.The emergence of Smart Campus is the inevitable trend of development of social life. ZigBee as a technology for Smart Campus is still in its infancy, but as the technology matures, the school intelligent systems will continue to improve, to promote education quality and level of education to a new height.
