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).(More)
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(More)
