ABSTRACT
This special issue comprises of 14 selected papers from the International Workshop on Computer Science for Environmental Engineering and EcoInformatics (CSEEE 2011). The conferences received 860 paper submissions from 15 countries and regions, of which 450 were selected for presentation after a rigorous review process. From these 450 research papers, through two rounds of reviewing, the guest editors selected 14 as the best papers on the Networking Technologies and Information track of the Conference. The candidates of the Special Issue are all the authors, whose papers have been accepted and presented at the CSEEE 2011, with the contents not been published elsewhere before.2011 International Workshop on Computer Science for Environmental Engineering and EcoInformatics will continue the excellent tradition of gathering world-class scientists, engineers and educators engaged in the fields of Computer Science and Environmental Biotechnology to meet and present their latest activities. CSEEE 2011 held on July 29-31, 2011, Kunming, China. This conference is sponsored by International Association for Scientific and High Technology, and is in cooperation with Yunnan University, and it is technical co-sponsored by Kunming University of Science and Technology.“Multi-Constrained Routing Algorithm for Multimedia Communications in Wireless Sensor Networks”, by Xin Yan, Layuan Li and F. J. An, proposes a novel routing model that can depict multiple service requirements in multimedia sensor networks, and designs a new multi-constrained routing algorithm MCRA for multimedia communications. Theoretical analysis and simulation experiments are provided to validate their claims.“Reputation-aware Service Selection Based on QoS Similarity”, by Shenghui Zhao, Guoxin Wu, Guilin Chen and Haibao Chen, proposes a reputation evaluation method for Web Services which can gradually adjusting the reputations based on eliminating the collusive behaviors of consumers step by step. The experimental results show that the model can identify the conclusive consumers and improve the exact rate of reputation evaluation and success rate of service selection.“Cost Aggregation Strategy with Bilateral Filter Based on Multi-scale Nonlinear Structure Tensor”, by Li Li and Hua Yan, proposes a novel cost aggregation method for stereo matching with modified bilateral filter. By constructing the multi-scale nonlinear structure tensor and adding the new corresponding weight in cost aggregation, more pixels similar with central pixel are aggregated in a support window and the final disparity map are more accurate..“A Collaborative Nonlocal-Means Super-resolution Algorithm Using Zernike Monments”, by Lin Guo and Qinghu Chen, proposes an efficient improved algorithm by introducing Zernike moments as representation of image invariant features into similarity measure. Experimental results indicate the proposed method can handle real video sequences with general motion pattern, and performances better than the comparing methods.“Mathematical Model and Hybrid Scatter Search for Cost Driven Job-shop Scheduling Problem”, by Jie Bai, Kai Sun and Gen Ke Yang, proposes a cost driven model of the job-shop scheduling problem in which the solutions are driven by business inputs, such as the cost of the product transitions, revenue loss due to the machine idle time and earliness/tardiness penalty.“Multi-objective Genetic Algorithm for System Identification and Controller Optimization of Automated Guided Vehicle”, by Xing Wu, Peihuang Luo and Dunbing Tang, proposes a multi-objective genetic algorithm (MOGA) with Pareto optimality and elitist tactics for the control system design of automated guided vehicle (AGV).“WebVR—Web Virtual Reality Engine Based on P2P network”, by Zhihan Lv, Tengfei Yin, Yong Han, Yong Chen and Ge Chen, introduces a multi-user online virtual reality engine -- WebVR. The core model innovation of WebVR engine is mapping the geographical space and virtual space to the P2P overlay network space, and build quad-tree index for the three spaces, and they identify the geocoding based on Hash value, which is used to index the user list, terrain data, and the model object data. The model greatly improves the hit rate of 3D geographic data search under P2P overlay network.“An Energy-Efficient Communication Protocol for Wireless Sensor Networks”, by Fengjun Shang, proposes an energy-efficient Single-Hop Active Clustering (SHAC) algorithm for wireless sensor networks. Through both theoretical analysis and numerical results, it is shown that SHAC prolongs the network lifetime significantly against the other clustering protocols such as LEACH-C and EECS.“Robust Cross-layer Design of Wireless Multimedia Sensor Networks with Correlation and Uncertainty”, by Lei You and Chungui Liu, uses a cross-layer method to deal with the robust lifetime optimization of wireless multimedia sensor network (WMSN) with energy consumption uncertainty and proposes to model the uncertainty as a polyhedral set.“The E-Commerce Model of Health Websites: An Integration of Web Quality, Perceived Interactivity, and Web Outcomes”, by Chung-Hung Tsai, integrates web quality (system quality, information quality, and service quality), perceived interactivity (human-message, human-human), and web outcomes (web usage, web satisfaction, and web loyalty) to explore the e-commerce model of health websites. A survey of 1076 users of health websites was conducted to validate the proposed model. The findings show that web quality has significantly positive effect on perceived interactivity, web usage, and web satisfaction separately, which in turn influence web loyalty.“A New Method of Time-frequency Synthesis of Harmonic Signal Extraction from Chaotic Background”, by Erfu Wang, Zhifang Wang, Jing Ma and Qun Ding, proposes a new synthesis about wavelet threshold and empirical mode decomposition (EMD) complementary of new harmonic signal extraction by experimental simulation.“Provable Data Possession of Resource-constrained Mobile Devices in Cloud Computing”, by Jian Yang, Haihang Wang, Jian Wang, Chengxiang Tan and Dingguo Yu, proposes a novel PDP scheme, in which a trusted third-party agent (TPA) takes over most of the calculations from the mobile end-users. By using bilinear signature and Merkle hash tree (MHT), the scheme reduces communication and storage burden, and is fit for mobile devices.“Image Compression based on improved FFT Algorithm”, by Juanli Hu, Jiabin Deng and Juebo Wu, adopts Radix-4 Fast Fourier transform (Radix-4 FFT) to realize the limit distortion for image coding, and to discuss the feasibility and the advantage of Fourier transform for image compression. It aims to deal with the existing complex and time-consuming of Fourier transform, according to the symmetric conjugate of the image by Fourier transform to reduce data storage and computing complexity.“Correlative peak interval prediction and analysis of chaotic sequences”, by Qun Ding, Lu Wang and Guanrong Chen, proposes a digital circuit design for the logistic-map module used in chaotic stream ciphers, analyzes the factors that may affect the output of the sequences, and develops a calculation method for estimating the output sequential correlative peak interval.We wish to thank the Kunming University of Science and Technology for providing the venue to host the conference.
