Distributed 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 کاملDynamic power control for energy harvesting wireless multimedia sensor networks
Optimization of energy usage in wireless sensor networks (WSN) has been an active research field for the last decades and various approaches have been explored. In fact, A well designed energy consumption model is the foundation for developing and evaluating a power management scheme in network of energy constrained devices such as: WSN. We are interested in developing optimal centralized power...
متن کاملAn Adaptive Header Compression Scheme in Wireless Multimedia Sensor Networks
Wireless multimedia sensor networks (WMSNs) transfer information-intensive data (e.g. audio, video, image), so it is necessary to utilize wireless channel efficiently. Header compression is a useful mechanism which can reduce the amount of data transferred and can improve channel utilization efficiency. Based on the characteristics of WMSNs, an advanced adaptive header compression (AAHC) scheme...
متن کاملOptimization 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 کاملAn Image Compression Scheme in Wireless Multimedia Sensor Networks Based on NMF
With the goal of addressing the issue of image compression in wireless multimedia sensor networks with high recovered quality and low energy consumption, an image compression and transmission scheme based on non-negative matrix factorization (NMF) is proposed in this paper. First, the NMF algorithm theory is studied. Then, a collaborative mechanism of image capture, block, compression and trans...
