Optimization parameter for mpeg-4 data over wireless sensor network

Conventional Wireless Sensor Network (WSN) always deals with scalar data such as temperature, humidity, pressure and lights. These types of data are very suitable for low rate and low power networking technology such as IEEE802.15.4. Transmitting a video for IEEE 802.15.4 standard is an interest due...
