Wireless Sensor Networks (WSN) mainly deal with scalar data such as temperature, humidity, and light which are very suitable for low rate and low power IEEE 802.15 based networking technology. The commercial off-the-shelf (COTS) CMOS camera has fostered researchers to push WSN a step further. The unique properties of multimedia data delivery pose fresh challenges for resource constrained sensor networks. Transmitting raw data is very costly while limited processing power prevents sophisticated multimedia processing at the sensor nodes. Wireless sensor networks offer an attractive choice for low cost solutions for transmitting data wirelessly to a database to be evaluated.
