Optimization of Energy Consumption in Image Transmission in Wireless Sensor Networks (WSNs) using a Hybrid Method
In wireless sensor networks (WSNs), sensor nodes have limited resources with regard to computation, storage, communication bandwidth, and the most important of all, energy supply. In addition, in many applications of sensor networks, we need to send images to a sink node. Therefore, we have to use methods for sending images in which the number and volume of packets are optim...
متن کاملDistributed Image Compression and Transmission Scheme in Wireless Multimedia Sensor Networks
Wireless multimedia sensor networks will have a variety of applications. Meanwhile, WMSNs produce a large amount of image data. JPEG2000 is the popular image compression standard and have some advantages. However, JPEG2000 is also high complexity and cannot be realized in an individual senor node which is limited in memory capacity, computation power and energy. Distributed image compression an...
متن کاملEnergy Aware Image Compression in Wireless Sensor Networks
A wireless sensor network consists of groups of sensors or nodes using wireless links to perform distributed sensing tasks. Example tasks for wireless sensors are surveillance and security, environmental monitoring, transport and smart spaces etc. [1]. Energy management in these networks is crucial since battery-driven sensor nodes are severely energy-constrained. The two factors that affect th...
متن کاملEnergy Efficient Image Compression in Wireless Sensor Networks
Wireless Sensor networks are battery powered due to which their lifetime is very limited. In camera an equipped wireless sensor node, life time of sensor network is decreased quickly due to battery and processing power constraints when image is processed and is transferred to the destination. The image compression not only helps to reduce the communication latency but also gives energy efficien...
متن کاملAdaptive Multimedia Transmission in Wireless Sensor Networks
Multimedia transmissions over wireless sensor networks may provide valuable information of the monitored field, enhancing monitoring and control applications. However, multimedia streaming can considerably shorten the expected lifetime of battery-operated sensor networks due to the large amount of information to be transmitted from multimediaenabled source nodes. On the other hand, multimedia d...
