A smart security system in indoor environment using the Received Signal Strength Index (RSSI) is proposed in this paper. RSSI shows irregular wave pattern with low variance in common closed field. If dramatic RSSI signals happen in a closed environment, it means that someone may have entered the field or something has moved its position. Furthermore, this new technology can simply be used as a wireless security system without the necessity of preparing any special experiment equipment, all that is required is a normal labtop and wireless LAN cards.
