Genetic Algorithm Based Clustering Techniques in Wireless Sensor Networks: A Comprehensive Study 基于遗传算法的无线传感器网络聚类技术研究
A. Sharaf, Shameem Ansar A, Manu J. Pillai
Wireless sensor network consist of small sensing devices also known as nodes capable of sensing environmental and physical parameters like temperature, humidity etc. and send the information to a central node known as sink or base station. Since the sensors are limited in energy, minimizing the energy dissipation and increasing the network lifetime is the key challenge faced by wireless sensor networks. In WSN, cluster based routing schemes are used for reducing energy consumption by data aggregation at intermediate nodes. Various traditional and meta-heuristic approaches for clustering are already implemented. But finding an optimal clustering and routing path is an NP-hard problem. Meta-heuristic algorithms such as genetic algorithm can be used in large scale wireless sensor networks to find the optimal clustering and routing scheme. In this paper a detailed study of state-of-the art genetic algorithm based clustering techniques in wireless sensor networks with their objective, characteristics etc. are presented. Different parameters used for the construction of the fitness function are also analyzed.
无线传感器网络由小型传感设备(也称为节点)组成,这些设备能够感知环境和物理参数(如温度、湿度等),并将信息发送到称为sink或基站的中心节点。由于传感器的能量有限,因此最小化能量损耗和延长网络寿命是无线传感器网络面临的关键挑战。在无线传感器网络中,为了减少中间节点的数据聚合所消耗的能量,采用了基于集群的路由方案。各种传统的和元启发式的聚类方法已经实现。但是找到最优的聚类和路由路径是一个np困难问题。遗传算法等元启发式算法可用于大规模无线传感器网络中寻找最优的聚类和路由方案。本文对无线传感器网络中基于遗传算法的聚类技术及其目标、特点等进行了详细的研究。分析了构建适应度函数所使用的不同参数。

Drizzle Detection through Histogram of Radon Projection (HRP) 基于氡投影直方图(HRP)的毛毛雨探测
M. Surekha, S. M. Roomi, J. Vignesh Kanna, S. M. Ebenezer
In hilly regions, frequent drizzling interrupts the daily activities of human beings and can also be deceptive. In this work, we develop a feature descriptor by Histogram of Radon Projection (HRP) to detect drizzle/rain. To compute this feature descriptor, initially we detect fine edges in an image utilizing the sobel gradient operator. Then the resultant image is divided into smaller cells and for each cell we estimate the count of radon transform values for different orientations and the weighted average for each transform coefficients are accumulated into bins. Finally, we use this radon feature descriptor to detect whether drizzling occurs in a given frame or not using Support Vector Machine (SVM).
在丘陵地区,频繁的毛毛雨打断了人们的日常活动,也可能具有欺骗性。在这项工作中,我们开发了一种基于氡投影直方图(HRP)的特征描述符来检测毛毛雨/降雨。为了计算这个特征描述符,我们首先利用sobel梯度算子检测图像中的精细边缘。然后将得到的图像分成更小的单元,对每个单元估计不同方向的氡变换值的计数,并将每个变换系数的加权平均值累积到bin中。最后,我们使用这个氡特征描述符使用支持向量机(SVM)来检测给定帧中是否发生毛毛雨。

N. P, Faheem Ali T
Nowadays high gain boost converters are efficient for many applications. This work introduces a high gain ultra boost converter with voltage regulation by increasing voltage gain and reducing voltage stress across the switch. This converter uses an autotransformer with coupled inductor integrating on the same core to achieve high output voltage about ten times of input voltage without using endmost duty cycle. And also a Switched/Diode voltage multiplier cell is using in coupled magnetic circuit to recycle the leakage energy. Methods used here for voltage regulations are Line regulation and Reference regulation. The simulation of proposed converter is verified using MATLAB/SIMULINK software. Modes of operation and analysis of the converter are also discussed.
目前,高增益升压变换器在许多应用中都是高效的。这项工作介绍了一种高增益超升压转换器,通过增加电压增益和减少开关上的电压应力来调节电压。该变换器采用集成在同一磁芯上的耦合电感自耦变压器,在不使用末端占空比的情况下,可实现约为输入电压十倍的高输出电压。并在耦合磁路中采用开关/二极管电压倍增器循环漏能。这里使用的电压调节方法有线路调节和参考调节。利用MATLAB/SIMULINK软件对所提出的变换器进行了仿真验证。文中还讨论了变流器的工作方式和分析。

Fossil fuels such as diesel, petrol etc are currently used as the main source of energy in supplying our society. However, these sources cause serious damage to our climate and global system by emitting greenhouse gasses. This will cause the major drawbacks to increase the environmental pollution and also the maximum utilization of vehicles increases the cost of the fuel. This indirectly increases the cost of living. Only 10% of vehicle is used as electric vehicles and they are depending on conventional energy sources. In order to cope with global change a fundamental change towards an energy system based on renewable is needed. Our project focuses on harvesting the energy from renewable energy resources such as solar, wind , electromagnetic sources . Centralized electricity systems are being integrated by a multitude of small distributed generation clusters, called Nano grids, capable of ensuring full utilization of renewable energy. Renewable energy plays an vital role in harvesting such a sources there by protecting the environment. With this innovative technology give a great change in reduce the cost of the fuel. The FPGA controls the panel using MPPT algorithm and provides the maximum power. Using multiple panels we can run smaller vehicles.
化石燃料,如柴油、汽油等,目前被用作供应我们社会的主要能源。然而,这些资源通过排放温室气体对我们的气候和全球系统造成严重破坏。这将造成主要的缺点,增加环境污染,也最大限度地利用车辆增加燃料的成本。这间接增加了生活成本。只有10%的汽车被用作电动汽车,它们依赖于传统的能源。为了应对全球变化,需要对以可再生能源为基础的能源系统进行根本性的变革。我们的项目侧重于从太阳能、风能、电磁等可再生能源中获取能量。集中式电力系统正被众多小型分布式发电集群(称为纳米电网)整合起来,能够确保可再生能源的充分利用。通过保护环境,可再生能源在获取这种资源方面起着至关重要的作用。有了这项创新技术,在降低燃料成本方面有了很大的变化。FPGA采用MPPT算法控制面板,提供最大功率。使用多个面板,我们可以运行较小的车辆。

Significance based Ship Detection from SAR Imagery 基于显著性的SAR图像船舶检测
S. Arivazhagan, W. L. Lilly Jebarani, R. Newlin Shebiah, S. Vineth Ligi, P. V. Hareesh Kumar, K. Anilkumar
Synthetic Aperture Radar images have potential applications in the surveillance scenario and hence automated target detection algorithms prove to be a useful tool in monitoring and crime control as well as in marine traffic management. The advancements in marine trade have lead to the increase in the number of ships in the world waters. The usage of satellite-based radar images have become well known for maritime surveillance as ship detection is relatively simple and independent of the climatic conditions. Ships can be easily discerned in the SAR images due to their bright intensity which results due to the strong radar backscatter from their metal surface. These are the significant pixels in an image which can be gathered to detect the ship targets. During heavy sea state conditions and presence of speckle noise, sea ice and coastline structure, the ship detection process is affected since these non-ship features in the sea also exhibit high intensities in the SAR image. These false alarms have to be reduced. So, in this work a Significance based ship detection algorithm followed by a discrimination stage using ensemble classifier is proposed to differentiate the ship and non-ship targets. To enhance the ship detection process, the images are subjected to ridgelet transform based despeckling. The efficacy of the proposed Significance based target detection is proved by the obtained results.
合成孔径雷达图像在监视场景中有潜在的应用,因此自动目标检测算法被证明是监视和犯罪控制以及海上交通管理的有用工具。海洋贸易的进步导致了世界水域船舶数量的增加。基于卫星的雷达图像的使用已经成为众所周知的海上监视,因为船舶探测相对简单并且独立于气候条件。由于金属表面的强雷达反向散射,舰船在SAR图像中具有较强的亮度,可以很容易地识别出来。这些是图像中的重要像素,可以被收集来检测舰船目标。在恶劣的海况条件下,存在散斑噪声、海冰和海岸线结构,船舶检测过程受到影响,因为这些海上非船舶特征在SAR图像中也表现出高强度。必须减少这些假警报。因此,本文提出了一种基于显著性的船舶检测算法,然后采用集成分类器进行识别,以区分船舶和非船舶目标。为了提高船舶检测效果,对图像进行了基于脊波变换的去斑处理。所得结果证明了基于显著性的目标检测方法的有效性。

Optimal Energy Consumption Protocol To Improve Qos In Delay Tolerant Networks 提高时延容忍网络Qos的最优能耗协议
Dr.LAKSHMI PRABHA KARUPPIAH, S. Selvan
Delay Tolerant Networks(DTNs) characterized by long delays and intermittent connectivity provides communication even in areas, earlier considered inaccessible. Protocols meant for Internet cannot be used directly because of the above mentioned characteristics and the development of new protocols is important to improve the Quality of Service (QoS) of DTNs.Optimal Energy Consumption Protocol(OECP) for QoS improvement in DTNs is proposed. Number of encounters, residual hop count, expected delay and residual energy are the metrics considered to identify the next node to forward the message packet. Fuzzy logic is used to aggregate data of the above mentioned parameters, and this computational value is used to identify the forwarding node. The process of identifying the forwarding node is continued til the destination node is found.Simulation experiments done using NS 2 proves that OECP has higher packet delivery ratio and lower energy consumption, end to end delay, when compared with the two existing routing protocol for DTNs. Statistical analysis using one way ANOVA with Tukey HSD method was done to prove that proposed protocol has significant performance over the other two protocols Epidemic and OOF.
延迟容忍网络(DTNs)以长延迟和间歇性连接为特征,即使在以前被认为不可访问的区域也能提供通信。由于上述特点,针对Internet的协议不能直接使用,开发新的协议对于提高DTNs的服务质量(QoS)非常重要。提出了一种用于改进DTNs QoS的最优能耗协议(OECP)。相遇次数、剩余跳数、预期延迟和剩余能量是确定下一个节点转发消息包的指标。采用模糊逻辑对上述参数的数据进行聚合,并以此计算值来识别转发节点。继续识别转发节点的过程,直到找到目的节点。利用ns2进行的仿真实验表明,与现有的两种DTNs路由协议相比,OECP具有更高的分组发送率和更低的能耗和端到端延迟。采用单向方差分析和Tukey HSD方法进行统计分析,证明所提出的协议比其他两个协议Epidemic和OOF具有显著的性能。
