Abstract
For data center cooling and intelligent substation systems, real time cabinet environmental monitoring is a strong requirement. Monitoring data, such as temperature, humidity, and noise, is important for operators to manage the facilities in cabinets. We here propose a sensing network, called CENet, which is energy efficient and reliable for cabinet environmental monitoring. CENet achieves above 93% reliable data yield and sends fewer beacons compared to periodic beaconing. It does so through a data-aided routing protocol. In addition, based on B-MAC, we propose a scheduling scheme to increase the lifetime of the network by reducing unnecessary message snooping and channel listening, thus it is more energy efficient than B-MAC. The performance of CENet is evaluated by simulations and experiments.

Summary
Cabinet environmental monitoring represents a typical application for wireless sensor networks [1,2]. From data center to substation, there are many cabinets and dedicated containers. These cabinets usually contain computers, high voltage switches, or other electronic equipments. Cabinet environmental monitoring is a technology that provides real-time recording of environment parameters in the interior of cabinets, such as temperature, humidity, smoking, noise, and so on. Depending on these data, operators can estimate the health and running status of the equipment in the cabinets. Operators need to identify the problem and make intelligent decisions on facility management
