Research ArticleOpen accessIn the author namesCross Layer Optimization Based on Rate Distribution in Multirate Wireless Sensor NetworkHonggang Wang, Dongming Peng, Wei Wang, Hamid SharifIt is important to increase the Wireless Sensor Network (WSN) lifetime, due to its limited energy resource, while meeting the constraints of applications. Recent Advances for In-Network Processing (INP) motivate many WSN applications which are based on multi rate and distributed signal processing, and therefore require the support of rate-based routing as well as MAC and link layer designs to … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,552 accessesView PDF Cite

Research ArticleOpen accessIn the author namesA Novel Image Component Transmission Approach to Improve Image Quality and Energy Efficiency in Wireless Sensor NetworksWei Wang, Dongming Peng, Honggang Wang, Hamid SharifDue to resource constraints, digital image transmissions are a significant challenge for image sensor based Wireless Sensor Networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called Image Component Transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Different components in the embedded wavelet image bit stream are considered and essential components … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,247 accessesView PDF Cite
