Smart Wireless Video Sensor Network for Fire Alarm

Smart Wireless Video Sensor Network (SWVSN) provides a new approach for fire detection and alarm. Compare with traditional approach, the system based on SWVSN proposed in this paper has features of smart event-oriented data processing, convenient arrangement, flexible network organizing. The system consists of three layers including camera node layer, base station layer and control layer. Due to using lower energy consumption CMOS image sensors, higher energy-efficient DSP processor and wireless communication modules compatible with the 802.15.4 protocol, SWVSN enables in-network image processing to reduce communication requirements while still consuming relatively lower power cost. Experimental results indicate that it can achieve the task of fire detection and alarm successfully.
