Hardwarely Handling Transmission Data Loss in a Low-Cost WiFi IoT Architecture for Energy and Environment Monitoring in a University Campus

This article describes improvements to a previously developed WiFi measurement platform for real-time monitoring of electrical and environmental parameters in a University Campus. The platform is based on data collected by low-cost IoT sensors able to communicate with the main server through MQTT protocol. This upgrade is dedicated to overcome the problem of data loss due to the occasional sensitivity of the WiFi communication network in some locations within the University Campus. As we hope in the future to use the gathered data to implement algorithms for energy prediction and profiling analysis, the more we suffer from data loss the more we can lose precision in our results, for that we did some modifications on our WiFi sensor nodes to get over any deficient connection between them and the destination server that can interrupt packages of the measured data to be transmitted so they get lost. In our case transmission errors leading to data loss is a major problem cause or main objective is not only to monitor the measured data in real-time but also the collection of it to analyze it in the future, leading us to figure out a solution to reduce this issue.
