In traditional WSNs, sensor nodes usually compress the data before sending them to the cluster head. However, this strategy may not be suitable for image transmission. If the image compression task rests mostly on camera-equipped node, it will deplete its energy quickly. To prolong the network lifetime, a novel network architecture is proposed in this paper. Except the camera-equipped nodes, all the...
Recently many of the potential WSN applications such as target tracking, process control and source localization have fostered the development of Wireless Multimedia Sensor Networks (WMSNs). The amount of image data gathered by camera nodes in WMSNs is very large. They need to be compressed before transmission. JPEG2000 is the state-of-the-art image compression standard which has many advantages,...
Currently most energy-constrained wireless sensor networks are designed with the object of minimizing the communication power at the cost of more computation because the energy consumption of traditional sensor nodes is known to be dominated by the communication functionalities. However, this may not be true in Wireless Multimedia Sensor Networks (WMSNs). Sometimes centralized image compression at...
