Abstract: This paper introduces a temperature control framework for smart homes using wireless sensor networks (WSN). A key issue with temperature monitoring and control is standard sampling techniques which take few temperature samples into consideration to make heating and cooling decisions in large areas of space. This results in poor controllability of temperature in unmonitored locations with potentially significant temperature variations in comparison with monitored locations. To solve this problem, spatial analysis techniques, namely geostatistical analysis, can be utilised to predict temperature in unmonitored locations to aid in making more informed decisions on how to heat and cool certain parts of a dwelling. Results show independent temperature control in defined areas using the proposed temperature control framework.

Keywords: smart homes; intelligent temperature control; WSNs; wireless sensor networks; context awareness; geostatistical analysis; classical variography; ordinary point kriging; temperature monitoring; home heating; home cooling.
