An implementation of MQTT through the application of warehouse management system for climacteric fruits and vegetables

Automation has became an inseparable part of today's world for which IOT has emerged as an excellent platform providing connectivity between various sensors, controllers and internet that enables remote monitoring and controlling of different environments subject to automation. Storage is an important aspect of the total logistic business as it directly affects the product quality and thus the total revenue. Considering the requirements of the perishable goods like climacteric fruits and vegetable storing warehouses this project propose a Warehouse Management System based on light-weight MQTT protocol which enables the user to monitor and control the storage conditions of fruits /vegetables all the time globally through the web page access. Further this system also provides quantitative fruits/vegetable freshness updates and on qualitative measures it gives fruits/vegetable rotting alerts. IOT is furnished with number of application layer protocols, thus this paper includes an overview and comparative results of two potential M2M communication protocols, MQTT and COAP, in terms of bandwidth consumption and network latency.
