| Abstract | This special issue of the Journal of Networks consists of six selected papers from the 4th International Conference on Ubiquitous Information Management and Communication (ICUIMC 2010) held in January 14th - 15th. Among them, six qualified papers have been selected as the papers for the special issue of the Journal of Networks, which covers the recent trends in wireless communications and networking.This issue includes various research field in communications and networking technologies. As one of the recent hot topics in this field, "A Communication Protocol for Sensor Database Construction by Rounding Sink" by Tomoki Yoshihisa and Shojiro Nishio, presents a model and simulation-based analytical results in wireless sensor networks. The rounding sink approach has been presented and studied, in which rounding sinks repeatedly wander about in the area to collect data from each sensor."An Efficient Mutual Authentication and Access Control Scheme for Wireless Sensor Networks in Healthcare" by Xuan Hung Le, Murad Khalid, Ravi Sankar, and Sungyoung Lee, also discusses an issue in wireless sensor networks. To achieve the protection of data confidentiality and patient privacy in healthcare applications using wireless sensors, a secure, lightweight public key-based security scheme is proposed and evaluated by simulation."An Energy-efficient Multi-candidate Greedy Routing Scheme in Wireless Sensor Networks" by Dang Tu Nguyen, Wook Choi, Minh Thiep Ha, and Hyunseung Choo, introduces novel multi-candidate greedy routing scheme in wireless sensor networks. According to the simulation results, their method increases the routing performance significantly in terms of packet delivery latency and energy efficiency.A fundamental technology for wireless communications is included in this issue as well. "The Enhanced Decoding Method for QO-SFBC System in Frequency Selective Fading Channel Environment" by Young-il Min, Hwan-min Park, Jun-hee Jang, Keun-dea Kim, and Hyung-jin Choi, proposes a decoding method to improve the performance of quasi orthogonal-space frequency block coding in frequency selective fading channel environment. An analysis and evaluation results by simulation show that the method can provide better performance compared with the conventional methods.This issue also deals with the field of image processing, which can be applied in the various Internet environments. "Image Retrieval with Generative Model for Typicality" by Taro Tezuka and Akira Maeda, discusses the problem to find the most typical image that depicts the object specified by a query. Their model consists of images, symbolic features, and latent semantic concepts (aspects), and experiments using both artificial and real data show the effectiveness of their method."A Simple Image Encoding Method with Data Lossless Information Hiding" by Zhi-Hui Wang, Chin-Chen Chang, Ming-Chu Li, and Tzu-Chuen Lu, presents a novel reversible data hiding method in the spatial domain for block truncation coding compressed grayscale images. The experimental results show that the scheme achieves high data hiding capacity at low compression rate.We would like to thank Sungkyunkwan University, Korea for providing the opportunity to hold the ICUIMC 2010 conference, which leads to selecting highly-evaluated papers in this special issue. In particular, we wish to acknowledge School of Information and Communication Engineering, Sungkyunkwan University, for their great efforts in preparing for the conference. We also thank all the authors for submitting the papers of their valuable results, which requires a lot of elaborative works until publication. We would like to deeply appreciate to the program committee members for their help in selecting papers for this special issue by thorough reviews under a tight schedule. Last, but not least, we wish to express our gratitude to the Editorial Board of the Journal of Networks for their efforts until publication.In closing, we sincerely hope that you will enjoy reading this special issue. |
