Efficient localization scheme with ring overlapping by utilizing mobile anchors in wireless sensor networks
Yeong-Sheng Chen, Yun-Ju Ting, Chih-Heng Ke, Naveen Chilamkruti, Jong Hyuk Park
Article No.: 20
This study proposes an efficient localization scheme in wireless sensor networks. The proposed scheme utilizes mobile anchors and is based on ring overlapping. In a wireless sensor network, the nodes that know their locations are called reference...
Data embedding in image-media using weight-function on modulo operations
Hung-Min Sun, Chi-Yao Weng, Shiuh-Jeng Wang, Cheng-Hsing Yang
Article No.: 21
Multimedia hiding system is to embed message behind the specified media, but it is still kept normal in media representations via human sensitive organizations without causing imperceptibility. In this article, we propose a data hiding system by...
Artistic image generation for emerging multimedia services by impressionist manner
Sanghyun Seo, Seungtaek Ryoo, Kyunghyun Yoon
Article No.: 22
In this article, we propose the rendering framework for painting-like image generation and general system architecture for mobile device. Especially, we focused on a color division method for generating neo-impressionist images. The French...
ENFFiS: An enhanced NAND flash memory file system for mobile embedded multimedia system
Sang Oh Park, Sung Jo Kim
Article No.: 23
Since the typical erase cycle limit of a NAND flash memory's block is about 1,000,000, flash memory should be erased as evenly as possible; otherwise, file system hot spots will soon be worn out. This forces a NAND flash memory file system to scan...
Thermal-aware task scheduling in 3D chip multiprocessor with real-time constrained workloads
Jiayin Li, Meikang Qiu, Jian-Wei Niu, Laurence T. Yang, Yongxin Zhu, Zhong Ming
Article No.: 24
Chip multiprocessor (CMP) techniques have been implemented in embedded systems due to tremendous computation requirements. Three-dimension (3D) CMP architecture has been studied recently for integrating more functionalities and providing higher...
