Distributed expectation maximization in Appointment Rumor Routing in WSN WSN中预约谣言路由的分布式期望最大化
H. Shokrzadeh, Nazanin Bazyar, Seyed Mohammad Yousefi Limanjoobi, S. Khorsandi
One of the major problem in wireless sensor networks is query-driven routing, which especially arises when Sink searches for data for which the location in the network is unknown. Event information is propagated by Rumor Routing in some selected paths in the network, and as a result, an event trace is created. A route to the location of the event is established when a query agent crosses an event trace. The main objective of all Rumor-based algorithms is to increase the cross over rate for the query-agents. In Appointment-based Rumor Routing, contrary to other query-driven algorithms, agents' cross over occurs in a predetermined location called appointment point. In previous works, the appointment point is centrally calculated at the base station. In this paper, a distributed algorithm is proposed for appointment point selection. In order to estimate the parameters and the rank of a Gaussian Mixture used to model event locations, a Distributed Expectation-Maximization algorithm is designed to estimate the rank and parameters. In this case, a data fusion algorithm as well as a novel approach called Active Gaussian Mean is employed to determine the appointment point. The results of simulation under multiple scenarios provide a comparison of the proposed algorithms with the ones in the literature. The results show that the proposed algorithms are nearly optimal.
无线传感器网络中的一个主要问题是查询驱动路由,特别是当Sink搜索网络中未知位置的数据时。事件信息通过谣言路由在网络中选定的路径上传播,从而创建事件跟踪。当查询代理穿过事件跟踪时,将建立到事件位置的路由。所有基于谣言的算法的主要目标是提高查询代理的交叉率。在基于预约的谣言路由中,与其他查询驱动的算法相反,代理的交叉发生在预定的位置,称为预约点。在以前的工作中,预约点是在基站集中计算的。本文提出了一种分布式的预约点选择算法。为了估计用于事件位置建模的高斯混合模型的参数和秩,设计了一种分布式期望最大化算法来估计秩和参数。在这种情况下,采用一种数据融合算法和一种称为主动高斯平均的新方法来确定约会点。多种场景下的仿真结果将所提出的算法与文献中的算法进行了比较。结果表明,所提出的算法几乎是最优的。

A security extension for securing the feedback & rating values in TIDE framework 用于保护TIDE框架中的反馈和评级值的安全扩展
I. Pranata, G. Skinner
In today's online environment, ratings and trust are paramount to the validity of transactions. Many consider the trustworthiness of an online entity prior to engaging in a transaction or collaboration activity. To derive entity's trustworthiness, feedbacks and ratings about this entity must first be collected electronically from other entities (i.e. raters) in the environment. As with any electronic transmission, security always becomes a crucial issue. The tampered feedback and rating values would result in an invalid measurement of an entity's trustworthiness. Thus, this issue needs to be addressed to ensure the accuracy of the trustworthiness computation. In this paper, we propose a security extension to our TIDE (Trust In Digital Environment) framework. This security extension upholds the integrity of feedback and ratings value during its electronic transmissions. The inclusivity of this method further maintains the accuracy of TIDE trustworthiness computation. In addition, this security extension can be universally applied in other trust and reputation systems.
在今天的网络环境中,评级和信任对交易的有效性至关重要。许多人在进行交易或协作活动之前会考虑在线实体的可信度。为了获得实体的可信度,必须首先以电子方式从环境中的其他实体(即评级机构)收集有关该实体的反馈和评级。与任何电子传输一样,安全始终是一个关键问题。被篡改的反馈和评级值将导致对实体可信度的无效测量。因此,需要解决这个问题,以确保可信度计算的准确性。在本文中,我们对我们的TIDE(信任在数字环境)框架提出了一个安全扩展。这种安全扩展在其电子传输过程中维护反馈和评级价值的完整性。该方法的包容性进一步保持了TIDE可信度计算的准确性。此外,这种安全扩展可以普遍应用于其他信任和信誉系统。

Towards an adaptive model to personalise open learning environments using learning styles 朝着一个自适应的模式,使用学习风格个性化开放学习环境
Heba A. Fasihuddin, G. Skinner, R. Athauda
Open learning represents a new form of online learning. It is based on providing courses, learning materials for free to be taken by any interested learner. The current model of open learning has certain limitations which provide potential for improvement. One such area is personalization in learning environments. One avenue to enhance learning experience in open learning environments is giving consideration to learning principles and cognitive science. This paper aims to introduce a proposal for an adaptive model to personalize the open learning environments based on the theory of learning styles and particularly the Felder and Silverman Learning Style Model (FSLSM). This model consists of two main agents to perform its functionalities. First, the identification agent which is responsible of identifying the learners' learning styles by monitoring certain determined patterns of learners' behaviors with learning objects while the learner interact with learning materials. Second, the recommender agent which is responsible of providing an adaptable navigational support based on the identified learning styles and preferences. The paper presents a description of the model and its functionalities including the patterns that can be monitored in open learning environments to identify the learning styles and also how the adaptation support can be provided based on the identified styles. Future implementation will test and verify this proposed model.
开放式学习代表了一种新的在线学习形式。它的基础是为任何感兴趣的学习者免费提供课程和学习材料。目前的开放学习模式有一定的局限性,这提供了改进的潜力。其中一个领域就是学习环境的个性化。在开放学习环境中提高学习体验的一个途径是考虑学习原则和认知科学。本文旨在介绍一种基于学习风格理论,特别是费尔德和西尔弗曼学习风格模型(FSLSM)的个性化开放学习环境的自适应模型。该模型由两个主要代理组成,以执行其功能。首先,识别代理负责识别学习者的学习风格,通过监测学习者在与学习材料互动时对学习对象的特定行为模式来识别学习者的学习风格。第二,推荐代理,它负责根据识别的学习风格和偏好提供适应性导航支持。本文介绍了该模型及其功能的描述,包括可以在开放学习环境中监控的模式,以识别学习风格,以及如何根据识别的风格提供适应支持。未来的实现将测试和验证这个提议的模型。

The influence of k-NN parameters on the localization accuracy of WSNs in indoor environment 室内环境下k-NN参数对WSNs定位精度的影响
B. Bengherbia, A. Toubal, Aboubakre Leboukh, Madani Amine Saidi
Localization is one of the most complex issues in wireless sensor networks (WSN) domain, particularly, when the network is in indoor environments where the effect of multipath propagation is more pronounced. In this paper we have focused on several factors that effect on the localization accuracy, including the target environment itself, as well as the various parameters of the program proposed in this paper, which is basically based on fingerprinting method, which uses the k nearest neighbor's technique (k-NN) to estimate target positions. The parameters discussed is the number k of neighbors around the target, the choice of the method to calculate the distance between the target and the various neighboring (Euclidean or Manhattan distance), and Wt the weight function.

Non-uniform decimation-free directional filter bank using histogram analysis for image enhancement 非均匀无抽取方向滤波器组使用直方图分析图像增强
N. Jawas, A. Arifin, Arya Yudhi Wijaya, A. Yuniarti, Wijayanti Nurul Khotimah
Directional Filter Banks (DFB) is a method for directional decomposition. It has been used in image enhancement procedure that involved image with many edges. The design of Decimation-Free Directional Filter Bank (DDFB) is made to give a better result for enhancement. However, the design cannot give an adaptive directional decomposition based on input image. In this paper, we proposed a Non-Uniform Decimation-Free Directional Filter Bank (NUDDFB) using Histogram Analysis for Image Enhancement. NUDDFB can build an adaptive directional filter depends on the input image. The result shows that NUDDFB can separate each directional image better than DDFB. The use of this method in image enhancement helps to retain the image from over enhancement.

Identification of levee strenght for early warning system using fuzzy logic 基于模糊逻辑的预警系统堤防强度识别
M. Rivai, K. Sambodho, H. Purnomo
There are still much potency of levee breaches in Indonesia. The levee strength is mostly influenced by the changing of its constituents. One of the key parameter of this phenomenon is the changing of soil water content in levee body. The increasing of soil water content will loosen the bonds among soil granules that may increase the potential of the levee breaches. The sequence of the changing parameter before levee breach is a crucial data. In this research, a monitoring system have been designed to collect the changing of soil water content using moisture sensor and to examine the changing of water level using ultrasonic sensor. These data will be further processed using fuzzy logic to identify the dangerous state describing the real of levee strength as an early warning system.
在印尼,决堤的可能性仍然很大。堤防强度主要受堤防成分变化的影响。这一现象的关键参数之一是堤体土壤含水量的变化。土壤含水量的增加会使土壤颗粒之间的联系松动,从而增加决堤的可能性。决堤前参数变化的先后顺序是一个重要的数据。本研究设计了一个监测系统,利用水分传感器采集土壤含水量的变化,利用超声波传感器检测水位的变化。这些数据将进一步用模糊逻辑进行处理,以识别描述堤防强度真实情况的危险状态,作为预警系统。

A new approach for lossless image compression using Reversible Contrast Mapping (RCM) 一种基于可逆对比度映射(RCM)的无损图像压缩方法
H. Mesra, H. Tjandrasa, C. Fatichah
This research introduces a new concept of compression with a different approach on lossless image compression that has been commonly known. The concept uses Reversible Contrast Mapping (RCM) which is a function of a simple integer transform developed for reversible watermarking method. The use of RCM in image compression is done similarly with the watermarking method. In this method, an image is divided into fixed-size blocks, the blocks are divided into two groups based on the data storage capacity. Blocks with smaller storage capacities are used as watermarks for the other blocks. The compression ratio of this method is similar to the Huffman compression. This method can also be used together with the Huffman compression technique to increase the overall compression ratio.
本研究引入了一种新的压缩概念,采用了一种不同于以往的无损图像压缩方法。该概念使用可逆对比度映射(RCM),它是为可逆水印方法开发的简单整数变换的函数。RCM在图像压缩中的使用与水印方法类似。该方法将图像分成固定大小的块,根据数据存储容量将块分成两组。存储容量较小的块用作其他块的水印。该方法的压缩比与霍夫曼压缩近似。该方法还可以与霍夫曼压缩技术结合使用,以提高整体压缩比。
