Monitoring Appliances Sensor Data in Home Environment: Issues and Challanges

In this paper our focus is on issues and challenges faced in monitoring energy consumption in the domestic sector and way forward to deal with these challenges. Implementing a sensor network to monitor energy consumption of household appliances in a meaningful way requires sophisticated network design. Such network has to deal with large amount raw sensor data coming from multiple sources. The challenge is how to collect necessary data and store it for producing intelligent advice on economical energy usage for household. One way of dealing with this challenge is to have smart sensor devices embedded in home appliances, however currently a vast majority of domestic appliances do not have even dumb sensor devices to enable access to their energy consumption data. In a typical home environment we can expect sensing devices with various capabilities ranging from passive device to intelligent and proactive devices.Raw data streams received from these devices need to normalised and represented in semantically equivalence manners.
