Internet of Things (IoT) solutions are becoming a fundamental asset in many different applications, from industry scenarios to agriculture and forestry. The positioning is therefore essential in order to obtain maximum performance from a Wireless sensor network. ![]() The findings show how different node arrangements provide significantly different reliability. Then, using the Fault Tree Analysis the real deployment of the nodes is taken into account considering the Wi-Fi coverage area and the possible communication link between nearby nodes. A reliability prediction based on different handbooks has been carried out to estimate the failure rate of the nodes self-designed and self-developed to be used under harsh environments. The reliability of the system has been evaluated by looking for both hardware failures and communication errors. ![]() In more detail, the paper analyzes the design and implementation of a wireless sensor network for low-power and low-cost applications and calculates its reliability considering the real environmental conditions and the real arrangement of the nodes deployed in the field. ![]() The aim of this work is to provide a deeper understanding about the way redundancy and node deployment affect the network reliability. ![]() Wireless Sensor Networks are subjected to some design constraints (e.g., processing capability, storage memory, energy consumption, fixed deployment, etc.) and to outdoor harsh conditions that deeply affect the network reliability.
