Design and Application of Interactive Teaching System for Electronic Engineering Specialty Based on ZigBee

Today, ZigBee technology has become one of the most widely used wireless communication technologies. Electronic engineering majors need a more efficient management system, which is supported by a database system to achieve overall learning management. The new system can improve students’ dominance in moral education and student leadership. Therefore, this system will also bring educational leadership. At the same time, this system is also the first of its kind. It is an interactive system for communication between schools, students, and parents. It provides a timely and comprehensive platform for information retrieval and management and improves educational arrangements, educational management and students. Nowadays, various colleges and universities are constantly reforming and innovating their teaching management systems, and their teaching methods are also more diversified. This leads to the increased complexity of teaching management, and the existing teaching system software functions cannot meet the increasing demand. Therefore, this paper first introduces the concept and characteristics of ZigBee technology; then, the routing algorithm of the ZigBee network layer is used to analyze the role of the ZigBee technology in interactive systems. In the undergraduate class, applying the interactive teaching system proposed in this paper to student practice, experiments were also performed on this system. The results show that it can be found that in the daily teaching management and operation, the system meets a variety of operational and performance requirements, which is actually the test steps passed before the platform is deployed. In addition, based on the characteristics of ZigBee, the system platform has good practicability and is easy to maintain; after making corrections to the exposed problems, good experimental results have been obtained, and the purpose of the system has been achieved.

Green urban environmental sustainability and health sport based on MapReduce fitness big data and ZigBee technology

Since the reform and opening up, China’s urbanization process has attracted worldwide attention, and the urbanization rate has been developing rapidly at an average annual rate of 1%. Urbanization has played an active role in promoting the transformation of economic structure and consumption structure, and alleviating the problem of overproduction. However, the rapid urbanization process has also exposed a series of problems, such as the emergence of urban development and social and natural ecological disharmony, urban functions and the imbalance of demand and the cultural characteristics of urban construction continue to occur. Planning is the key to determining the spatial, material and indirect spiritual form of the city. The emergence of these problems shows to some extent that urban planning is relatively short-sighted, focusing only on economic benefits, while ignoring ecological, social, and cultural and policy factors. In this article, we will analyze the current status of green city management and the significance of applying ZiBee technology by searching and researching a large number of materials related to ZigBee technology and green city management technology. It also compares the performance with the list of routing algorithms currently widely used in the ZigBee network layer. In the traditional ZBR routing algorithm, the redundancy of request messages is likely to cause flooding effects, the routing efficiency of the network is low, and the energy consumption of the network is high. • China’s urbanization rate has been developing rapidly at an average annual rate of 1%. • Urbanization has played an active role in promoting the transformation of economic structure. • Planning is the key to determining the spatial, material and indirect spiritual form of the city. • Analyze the current status of green city management and the significance of applying ZigBee technology.

Utilizing Neighbours-Table to Improve Tree Routing Protocol in ZigBee Network

ZigBee is an industrial standard for wireless ad hoc networks based on IEEE 802.15.4. It has been developed for low cost, low data rate and low power consumption. ZigBee's network layer defines two routing protocols namely Ad Hoc On-demand Distance Vector and Tree Routing (TR). TR protocol follows the tree topology (parent---child) in forwarding the data packets from source nodes to the sink node. However, the source does not find rather nor the location of the sink is close to the source node or if it is not in the sub-tree. In this case it will follow the tree topology which will use a lot of hops to deliver data packets to the sink node. This paper present an improvement of TR protocol for ZigBee network and is called Improved Tree Routing (ImpTR) protocol which is computationally simple in discovering the better path to transmit data packets to the sink node, and does not need any addition in hardware. ImpTR determines the better path to the sink node depending on the tables of the neighbouring nodes, which is part of the existing ZigBee network specification. Results show that the proposed algorithm provides shorter average end-to-end delay, increase throughput, decrease the average number of hops and decrease the energy consumption from the network when compared to the original TR routing protocol.

An Evaluation Study of Mobility Support in ZigBee Networks

Based on the IEEE 802.15.4 LR-WPAN specification, the ZigBee standard has been proposed to interconnect simple, low rate, and battery powered wireless devices. The deployment of ZigBee networks is expected to facilitate numerous applications, such as home healthcare, medical monitoring, consumer electronics, and environmental sensors. For many of the envisioned applications, device mobility is unavoidable and must be accommodated. Thus, providing ubiquitous connections to/from a mobile device is crucial for various future ZigBee applications. Knowledge of how nodal mobility affects the ZigBee routing protocol is important, but the lack of ZigBee simulator support has limited the amount of research, evaluation, and development in this area. Thus far, researchers have been unable to analyze and evaluate the impact of mobile applications via extensive simulations. In this paper, our contribution is threefold. First, we present an initial implementation of the ZigBee network layer in NS-2, which will allow further research and development to be conducted in this area. Second, we analyze the adequacy of current provisions for dealing with different mobility cases. Third, we provide a comprehensive set of simulation results that demonstrate the inefficacy of the current standard for handling mobility. Our results show that the ZigBee device plays a significant role in determining the routing performance in mobile scenarios.
