Selection of the Wireless Communication Topology Using IEEE 802.15.4 Standard

Abstract: In Wi-Fi networks it always exists, as a basic structure, a communication manager and a number of clients. Clients will always listen for the presence of one or more managers who tell them, among other information, the name of the network that they manage, the channel to use, the security and available authentication algorithms, etc. Based on this information and settings of the device in question, the client will be able to join the appropriate network. In our project, where we develop a communication system among students and teacher into a classroom, we use ZigBee protocol based on the IEEE 802.15.4 standard. Different topologies can be used with this purpose and in this paper several of them are analyzed. Among them, we have selected the nonbeacon-enabled cluster tree.
