Design of Hybrid Topology Wireless Sensor Network Nodes Based on ZigBee Protocol

Abstract

With the rapid development of wireless communication and embedded technology, wireless sensor networks (WSNs) have become an important part of the Internet of Things (IoT). Despite these advances, many current WSNs are still limited to a single topology and point-to-point communication, which greatly hinders communication efficiency and scalability and poses additional challenges for our communication networks. In this study, we propose a multi-node hybrid-topology sensor network that uses the CC2530 chip and ZigBee technology to overcome these problems. Single-structure wireless sensor networks have problems such as poor scalability, and damage to a terminal can cause the entire network to collapse. To solve these problems, we propose a new hybrid-topology model with the advantages of scalability and system stability. It also has a self-regulating mechanism, so that if a router is damaged, the terminal can be converted to a router to prevent the network from collapsing. We propose a new hybrid topology model using ZigBee wireless communication technology and the CC2530 chip. The aim of this research is to improve communication efficiency, reduce costs, and achieve high accuracy while meeting energy-saving requirements and measurement needs in a variety of environments. Finally, we studied the model’s scalability to further illustrate its superiority in the development of wireless sensor networks. The experimental results show that this method not only improves communication efficiency but also achieves flexibility.
