Energy-efficient scheduling strategies for parallel applications running on a homogeneous cluster can perform efficiently in conserving energy. In order to achieve the goal of optimizing performance and energy efficiency in clusters, we propose an energy-efficient Dependency-based task Grouping (DG) method to assign parallel tasks under precedence constrains to multi-core processors. Dependency degree is defined as the sum of the reduced communication time by assigning task paths with much intercommunication to one processor and the execution time of unexecuted redundant tasks on the same node. Our algorithms aim at reducing energy consumption and improving resource utilization by assigning the task paths with highest dependency degrees to one processor. Combining three existing schedule algorithms-TDS (Task Duplication Scheduling), EAD (Energy-Aware Duplication) and PEBD (Performance-Energy Balanced Duplication) with the DG method, we propose three improved algorithms-TDS-DG, EAD-DG and PEBD-DG. Compared with the three existing algorithms, the improved algorithms can save energy and improve computing resource utilization by 55.4% and 71.2% on average, respectively, at the cost of a slightly 2% performance degradation.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121146753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this algorithm, visual sensitivity for human beings to perceive stereoscopic image in frequency domain has been considered. Excepting for this important property related to Human Visual System (HVS), another property is also taken into account: contrast sensitivity function (CSF). In our algorithm, for the left reference block, its most matching block in the left view is found by using the block matching method, and the right reference block is searched based on disparity information as a vital feature in 3D image/video. In addition, its matching block for the right reference one is also finished. The processing mode is completed for the original and distorted stereoscopic images. Then, these blocks are processed by DCT and calculated by modified PSNR in view of CSF and Region of Interest (ROI) mechanism (visual sensitivity). The calculated results have demonstrated its validity compared with the subjective test results. And the proposed perceptual quality assessment metric outperforms other currently popular metrics.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121298612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resource limitations and vulnerabilities of wireless sensor node expose the network to suffer with numerous attacks. The WSN constraints and limitations should be taken under consideration while designing the security mechanism. The recent Biological inspired self-organized secure autonomous routing protocol (BIOSARP) requires certain amount of time at initialization phase of WSN deployment to develop overall network knowledge. Initialization phase is a critical stage in the overall life span of WSN that requires an efficient active security measures. Therefore, in this paper we propose E-BIOSARP that enhances the BIOSARP with random key encryption and decryption mechanism. We present the design, pseudo code and the simulation results to prove the efficiency of E-BIOSARP for WSN. Network simulator 2 (NS2) has been utilized to perform the analysis. Our result shows that proposed E-BIOSARP can efficiently protect WSN from spoofed, altered or replayed routing information attacks, selective forwarding, acknowledgement spoofing, sybil attack and hello flood attack.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125678443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since centralized key management schemes have the drawbacks of the single point of failure and performance bottleneck, distributed key management schemes are proposed to solve the problem. In this paper, we propose a distributed key management scheme using multilinear forms for multi-privileged group communications. The identifications are assigned to service groups (SGs) and session keys (SKs). Based on the relationship of SGs and SKs, a derivation technique is designed to allow the SG servers to efficiently determine the affected SKs on their own according to the identification of the SG in which membership changes. For one leaving/switching operation, a uniform rekeying material is negotiated between the related SGs by using multilinear forms. As a consequence, the affected SGs can deduce all the affected SKs through the previous keys or with the rekeying material by using one-way function. The security analysis shows that the proposed scheme is secure. The performance evaluation shows the proposed scheme reduces the communication cost greatly.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133783803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, this document focuses on a specific difference between SIP and IAX: the bandwidth, which is an essential parameter in order to design and optimize a VoIP network for an organization. One of the most important factors to consider when building VoIP networks is the proper capacity planning. About capacity planning, bandwidth calculation is an important factor to consider when designing and troubleshooting packet voice networks for good voice quality. This paper presents important explanations about the bandwidth utilization over VoIP networks, this include o take some theoretical foundations and calculate the bandwidth per media flow for a VoIP trunk, in which different voice codecs is enabled (specifically G. 711 and JSM) and when a VoIP protocol such as SIP and IAX. Voice over IP (VoIP) is used. These calculations will be compared here against the results obtained stats about traffic analysis from some network analyzers over a physical Ethernet trunk between two Asterisk servers into a specific LAN, simulating two different branches for an organization. Both the analysis of the results obtained and the proper conclusions from this work, are useful when calculating the maxim number of simultaneous calls or the minimal capability of a data link, necessary for a single number of voice conversations, taking into account the audio codecs used and signaling and data flow protocols.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116944090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This challenge demands dynamic capabilities to sustain its competitive advantage. One such a capability is the knowledge absorption capability (i.e. absorptive capacity) that can be described as the ability of an organization to acquire, assimilate, transform and exploit knowledge gained from external sources. Absorptive capacity operationalization refers to the functioning of its dimensions. Although absorptive capacity has been extensively studied, the role of trust in operationalizing absorptive capacity is not yet been investigated. This research seeks to understand the role of trust in each of the absorptive capacity dimensions. A qualitative research methodology is employed through exploratory case studies to answer the research question, using semi-structured interviews as a dynamic data collection strategy. A theoretical framework is proposed to further understand the relationship between trust and absorptive capacity. A model will be developed to guide organizations to enhance absorptive capacity towards innovation, improved performance and competitive advantage. The paper is representing work in progress and the framework is currently being tested in the Healthcare industry in Australia.","PeriodicalId":206739,"journal":{"name":"2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131433210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
