Wireless sensor/actuator networks (“sensornets”) represents a new computing class consisting of large number of nodes which are often embedded in their distributed operating environments. The emergence of this new computing class raises many system design challenges. One of the major challenges is to develop a very lightweight routing protocol which can run on this low powered, low memory equipped tiny devices. Traditional routing algorithm such as DV, AODV, Link-State, Dijkstra etc requires routing table along with other data structure which is not suitable in the case of sensornets. ZigBee alliance has proposed a routing protocol which works on mathematical formula and consumes less resources but it has limitation on network breadth depth etc. We addressed network depth problem in our paper “Address Borrowing in Wireless Personal Area Network” [1], addressed network breadth problem in our papers “Single Level Address Reorganization In Wireless Personal Area Network” [2] & “Multilevel Address Reorganization Type 2 I N Wireless Personal Area Network”[3]. Similarly we tried to tackle linear network problem in our paper “WPAN Routing Using Huffman Technique” [4]. We have addressed link failure problem of dynamic network in our paper “Multi Channel Personal Area Network (MCPAN) Formation and Routing” [5]. Now here in this paper we will discuss about a routing framework which can be applied in any operating space. It uses all the techniques discussed so far in above mentioned papers. In real world almost all the operating space is asymmetric in nature.
无线传感器/执行器网络(“sensornets”)代表了一种由大量节点组成的新型计算类，这些节点通常嵌入在其分布式操作环境中。这种新的计算类的出现提出了许多系统设计挑战。主要的挑战之一是开发一种非常轻量级的路由协议，它可以在这种低功耗、低内存的微型设备上运行。传统的路由算法如DV、AODV、Link-State、Dijkstra等都需要路由表和其他数据结构，这在传感器的情况下是不适用的。ZigBee联盟提出了一种基于数学公式的路由协议，该协议对资源消耗少，但在网络宽度、深度等方面存在限制。我们在“无线个人局域网中的地址借用”一文中讨论了网络深度问题[1]，在“无线个人局域网中的单级地址重组”[2]和“2 I N无线个人局域网中的多级地址重组”[3]中讨论了网络宽度问题。同样，我们在论文“使用霍夫曼技术的WPAN路由”[4]中尝试解决线性网络问题。我们在论文《多通道个人区域网络(Multi Channel Personal Area network, MCPAN)的形成和路由》[5]中解决了动态网络中的链路失效问题。在本文中，我们将讨论一个可以应用于任何操作空间的路由框架。它使用了到目前为止在上述论文中讨论的所有技术。在现实世界中，几乎所有的操作空间本质上都是不对称的。

Efficient and reliable data transmission and storage are the challenging issues in modern communication system. Reproduction of reliable data has been achieved by controlling the errors in a noisy environment. To control this errors data has been coded properly by considering different coding techniques. Turbo Code (TC) is considered as one of the high-performance forward error correcting coding schemes which approaches to the Shannon limit. Here, a novel Parallel Concatenated Convolution Turbo code (PCCTC) has been proposed to improve the Bit Error Rate (BER) performance portentously by allocating optimized power in systematic and parity bits. BER performance of the system has been improved by using two symmetrical convolutional encoders. Through the simulation result, it is observed that the proposed Flower Pollination Algorithm (FPA) optimized Parallel Concatenated Convolution Turbo Code (PCCTC) provides better error performance over Uniform Power Allocation (UPA) based PCCTC as well as Harmony-Search (HS), Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) optimized PCCTC.

Transformer-less photovoltaic (PV) systems have the advantages of higher system efficiency, reduced cost and size of the system. A single phase half bridge inverter topology does not inject dc into the grid, but its output voltage has only three levels, thus lower power quality. This paper proposes a transformer-less topology for improving the power quality of the inverter output voltage, and increasing its power rating. Level and phase shifted sinusoidal pulse-width modulation (LPSPWM) technique is used for PWM generation. Simulation results obtained in MATLAB Simulink are compared with the conventional one.

An improved fuzzy PID controller is designed with fuzzy rule-based set-point weighting mechanism. The proposed fuzzy PID controller is designed by adding control actions of fuzzy PI and fuzzy PD controllers with proper scaling factors. The set-point weighting factor is obtained online through a simple fuzzy inference system based on process change of error. The proposed fuzzy set-point weighting scheme offers a considerable amount of performance improvement for second order linear and nonlinear processes compared to other well-known set-point weighting techniques. This fact has been verified through simulation study and real time implementation on a DC servo position control system. Performance analysis reveals that the proposed scheme is able to provide performance enhancement during both set-point tracking and load rejection phases along with substantial robustness during close-loop operation.

A new hybrid particle swarm optimization algorithm based on black-hole theory called modified black-hole particle swarm optimization (MBHPSO) is introduced in the present paper. Placement of capacitor of optimal sizes and at optimal locations not only reduces the power losses, but also improves the voltage stability of the electric power systems. Several meta-heuristic techniques have been used by Scientists and researchers over the years to address the problems of capacitor placements. They are very effective and powerful in comparison with conventional methods in solving complex nonlinear constrained optimization problems. But one of the major difficulties for these methods is the premature convergence. A new improved hybrid technique is introduced in this paper that addresses the issues of premature convergence successfully for the present problem. The accuracy, performance and effectiveness are authenticated by testing the algorithm proposed in the present paper on a test system. The present paper also compares the results with those obtained by applying several other modern techniques such as fuzzy reasoning, plant growth simulation algorithm, opposition based differential evolution. The outcomes of the experiment show that high quality solutions can be obtained by the proposed method.

Steam temperature Control is one of the most challenging control loops in a power plant boiler because it is highly nonlinear and has a long dead time and time lag. Proper control of Superheated steam temperature is extremely important as high temperature can damage the superheater or high pressure turbine and low temperature will reduce the efficiency of power plant. Therefore, the Superheated temperature is to be controlled by adjusting the flow of spray water to within +/-10 deg C during transient states and +/-5 deg C at the steady state. In this paper, the Control using fuzzy gain adaptation of PID controller is presented. Fuzzy rules are utilized on-line to determine the controller parameters based on error and its first time derivative. Simulation and experimental results of the proposed scheme show good performances compared to the PID controller with fixed parameters in terms of dynamic and steady state characteristics of all loops. Simulations are performed using MATLAB/SIMULINK.

A user in IEEE 802.11(Wi-Fi) system must associate to a particular Access Point (AP) to communicate through the Internet. According to the current association method which is based on Receive Signal Strength Index(RSSI), the user first identify its convenient APs and associate with the strongest AP, excluding the fact whether that AP is overloaded or not. In current scenario, the wireless network is increasingly being connected to a wired backbone. This allows the AP's out of band communication among them and leaves opportunities for improved protocol design. As users are not always uniformly distributed in real time networks, some AP's goes through heavy load and some sits idle. In this paper we have tried to modify the existing system by introducing a novel WLAN network architecture that consists of a Master AP, connected to a wired backbone network which will periodically gather information about different subordinate APs connected to it. The coverage of Master AP is much greater so that it can cover the entire area of all other subordinate APs. The Master AP sends the beacon packet which contains the RSSI and existing load of subordinate AP/ APs, if the user is in coverage area of those subordinate AP/APs. This paper mainly concentrated on how the existing load of different subordinate APs will be calculated in Master AP. The existing beacon format (based on RSSI) is modified so that it can also send the existing load with the RSSI field to mobile nodes which are in the coverage of subordinate AP/APs. As a result, the nodes can make a proper judgment on which AP to connect, not only based on RSSI but also by checking the existing load of that AP. In our results we have shown that our proposed scheme performs better than RSSI and Least load first in several scenarios.
IEEE 802.11(Wi-Fi)系统中的用户必须关联到特定的接入点(AP)才能通过Internet进行通信。根据目前基于RSSI (Receive Signal Strength Index)的关联方法，用户首先识别出自己方便的AP，并与最强的AP进行关联，而不考虑该AP是否过载。在目前的情况下，无线网络越来越多地连接到有线骨干网。这允许AP在它们之间进行带外通信，并为改进协议设计留下了机会。由于用户并不总是均匀分布在实时网络中，因此有些AP负载过重，有些AP处于空闲状态。在本文中，我们试图通过引入一种新的WLAN网络架构来修改现有系统，该架构由一个主AP组成，连接到一个有线骨干网，该骨干网将定期收集连接到它的不同从属AP的信息。主AP的覆盖范围要大得多，因此它可以覆盖所有其他从属AP的整个区域。如果用户在从属AP/AP的覆盖范围内，则主AP发送包含从属AP/AP的RSSI和现有负载的信标报文。本文主要研究如何在Master AP中计算不同从属AP的现有负载，修改现有的信标格式(基于RSSI)，使其也可以将带有RSSI字段的现有负载发送到从属AP/AP覆盖范围内的移动节点。因此，节点不仅可以根据RSSI，还可以通过检查该AP的现有负载来正确判断连接哪个AP。在我们的结果中，我们已经表明，我们提出的方案在几个场景中比RSSI和Least load first表现得更好。

Using the Internet Of Things Technology for supervising solar photovoltaic power generation can greatly enhance the performance, monitoring and maintenance of the plant. With advancement of technologies the cost of renewable energy equipments is going down globally encouraging large scale solar photovoltaic installations. This massive scale of solar photovoltaic deployment requires sophisticated systems for automation of the plant monitoring remotely using web based interfaces as majority of them are installed in inaccessible locations and thus unable to be monitored from a dedicated location. The discussion in this paper is based on implementation of new cost effective methodology based on IoT to remotely monitor a solar photovoltaic plant for performance evaluation. This will facilitate preventive maintenance, fault detection, historical analysis of the plant in addition to real time monitoring.

This will facilitate preventive maintenance, fault detection, historical analysis of the plant in addition to real time monitoring.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114888790","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}
