The efficiency of communication between devices in low-speed networks is very important for their period of performance and life expectancy. In addition, development, simulation and optimization of new researching models before their practical realization leads to reduction of time and considerable financial resources. Here we explore energy efficiency of low-speed network configurations based on the distance between nodes. The results from a set of simulations under various topology scenarios and network parameters enabled the assessment of energy efficiency in a given network.
The Internet of Things (IoT) applications use wireless technologies in order to establish Internet connection. Communication technologies such as Wi-Fi, cellular, ZigBee, Bluetooth, etc. are used to transfer data in IoT. The choice of the appropriate technology or combination of technologies depends on the type of application, its characteristics, user requirements, and other factors such as communication range, security requirements, battery life, etc. In our project, we will focus on Star, Cluster and Mesh wireless topologies, conduct comparative analysis between them, and testing different XBee devices with specialized software. The experiments are connected to the quality of the transferred data using different XBee devices and how this will affect the transmission range. The results of our research show that in terms of the range and quality of packet transmission, the cluster topology shows the best results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
