An 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...
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 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 کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
متن کاملTarget Tracking Based on Virtual Grid in Wireless Sensor Networks
One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...
