The solar irradiation and temperature are mainly depends on the output power produced from the PV conversion process. The Boost Converter is used to obtain the maximum power and is controlled by the Fuzzy logic controller. The Sinusoidal Pulse Width Modulation (SPWM) produces the soft switching control strategy for the proposed topology. The proposed system involves a Stand-Alone Photovoltaic System, Boost converters, Fuzzy Logic Controller, Three Phase inverter and a load. The regulated voltage and current from the boost converter is fed to the inverter circuit which is connected to the load with a continuous maximum power. The fuzzy logic controller is used to improve the boost converter efficiency and the sinusoidal PWM is used to give pulses for the inverter circuit. The inverter output current for driving a load should be noted such that it does not carry the harmonic content. However since disturbed sine wave is unavoidable under various factors it is necessary to reduce the harmonic level to obtain a highly effective output. The results are generated in MATLABSIMULINK and are shown.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123800576","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}

With the popularity of cloud services, some applications require searching in multilingual environment. Other applications require data to be stored in the cloud in encrypted form and outsourced to a third party for processing. This paper proposes an algorithm using bloom filters to perform efficient multilingual search on data stored in the cloud in plain or encrypted form. When the user sends in a keyword to be searched, its language is first determined and its corresponding language list bloom filters are checked for presence of the keyword. To make the algorithm more efficient and accurate, we have created two categories of bloom filters namely primary and secondary bloom filter. The list of documents having the keyword is returned to the user. For secure applications, the encrypted documents and its corresponding bloom filters are stored in the server. When user wants to perform a search in stored encrypted documents it sends the keyword to the server. The server applies similar technique to return the encrypted documents having the keyword and the client uses the key to decrypt the documents if required. While searching for keywords, we test the word against the bloom filter of documents which enables these to be stored in encrypted form. Checking of a word against the bloom filter of its documents takes constant time. Experimental results show that searching for a word in encrypted documents can be performed quite efficiently using this scheme even if the environment is multilingual.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133506234","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 paper proposes DDDOST, a novel approach for filtering flooding attack, the most severe denial-of-service attack that occurs at the transport layer of the internet. Flooding attack at the transport layer affects the transmission control protocol's three-way handshake process, thereby denying the services of TCP. It also denies the services of user datagram protocol. The main objective of this approach is to install local and global monitoring agents at various points in the network in order to monitor and filter real-time TCP traffic and UDP traffic thereby allowing legitimate traffic to flow in the network during attack traffic filtration process and to avoid buffer overflow at the monitoring agents. DDDOST consists of a novel agreement mechanism and a novel detection algorithm and it works taking the clock values of each node into account for effective detection of the attack which has not been used in the existing defense mechanisms. All nodes within a network are permitted to have a synchronized clock value. In the agreement mechanism, the IP address spoofing is prevented which forms the gateway for flooding attacks and once IP spoofing is prevented, the detection mechanism is carried out in detecting and filtering flooding attacks. This distributed defense mechanism reduces the burden on a single global monitoring agent thereby introducing local monitoring agents at various points in the network. The performance results show that this approach effectively and accurately detects and filters DOS attacks within a short period. The performance of this proposed mechanism has been measured in terms of time delay and false positive ratio and it is compared with existing defense mechanisms and it is found to be effective over existing defense mechanisms.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133921884","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}

It does not require any fixed infrastructure due to no wired backbone. It is suitable to use in environment that have a need of on the fly set-up. Every host is a router and packet forwarder. Each node may be mobile, and topology changes frequently and unpredictably due to the arbitrary mobility of mobile nodes. This aspect leads to frequent path failure and route rebuilding. Routing protocol development depends on mobility management, efficient bandwidth and power usage which are critical in ad hoc networks. In this paper, personalized Ad hoc On demand Distance Vector (RAODV) algorithm to reduce the link break scheme for mobile ad hoc networks. This present approach reduces packet loss and finds optimized route by taking into consideration of bandwidth, delay which results by improvement of quality of service. The performance analysis and simulation are carried out to evaluate network performance using network simulator NS-2 based on the quantitative basic parameters like throughput, delay in term of number of nodes and various mobility rates. A simulation result was during the comparison of AODV protocol with RAODV the probability of link break has been decreases in RAODV considering when various pause times and increases number of nodes.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133141126","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}

WSNs are application specific, hence all design considerations are different for each application. This paper highlights the technique like animals as mobile biological sensors and it is based on existing animals tracking systems used for zoological studies and space-bound/earth-bound observational techniques. The abnormal behaviour of animals prior to earthquake occurrence in seismically active region can be used to predict the earthquake because animals have relatively more capability than humans to perceive certain kind of geophysical stimuli which may precede earthquake. The space-bound and earth-bound observational techniques can be used to detect early warning signals from places where stress builds up deep in the earths crust that may lead to a catastrophic earthquake. Middleware for WSN is a software infrastructure with heterogeneous features that binds together the different applications, network hardware, operating systems, and network stacks. The task of middleware is to act as an interface between WSNs and end user system, it will process data which is taken from sensor devices and bio-sensors.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133140954","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}
