Monitoring Appliances Sensor Data in Home Environment: Issues and Challanges

In this paper our focus is on issues and challengesfaced in monitoring energy consumption in thedomestic sector and way forward to deal with thesechallenges. Implementing a sensor network to monitorenergy consumption of household appliances in ameaningful way requires sophisticated network design.Such network has to deal with large amount rawsensor data coming from multiple sources. Thechallenge is how to collect necessary data and store itfor producing intelligent advice on economical energyusage for household. One way of dealing with thischallenge is to have smart sensor devices embedded inhome appliances, however currently a vast majority ofdomestic appliances do not have even dumb sensordevices to enable access to their energy consumptiondata. In a typical home environment we can expectsensing devices with various capabilities ranging frompassive device to intelligent and proactive devices.Raw data streams received from these devices need tonormalised and represented in semanticallyequivalence manners.
