This model is based on considering the Data Burst (DB) blocking probability at the optical node together with physical channel impairments like fiber cut between the nodes, for ensuring the QoS demanded. Here the primary importance is given for preventing the Data Burst (DB) loss while propagating from an ingress node to an egress node through intermediate switching nodes. At each node, prior information about the blocking probability in the immediate successor node and detection of fiber cuts between the nodes are required. So a non-homogenous Markov chain is used to find state of the node in relation to DB blocking probability after `n' states of the node. Upon detecting the fiber cut or probability of DB blocking in the immediate successor node, the present node invokes a Genetic algorithm to find the alternate shortest path for bypassing the immediate succeeding node in the specified light path. Furthermore, the blocking probability of DB with and without the Fiber Delay Lines (FDL) are considered and compared in this paper.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125023343","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 puts its own priority over the conventional CDMA to provide broadband access in cellular wireless communication. A new overloading scheme for the uplink of cellular CDMA has been proposed in [7] using unequal chip delay spreading (UCDS). It divides all the active users into G groups with each group containing L number of users. Each user in a group is assigned the same orthogonal code, but with different chip durations (multiple of Tc/L). For spreading, all the L Users in a group use the assigned unique code with the insertion of predefined time delay. During spreading each user in a group has to go through unequal time delay between each successive spreading chip. Addition of suitable delays helps in maintaining the correct time alignment among all the users in a group. The receiver uses a very simple orthogonal successive interference cancellation (OSIC) multi user detector in order to recover the message bits of all the users. In this paper, the performance of this new overloading scheme (UCDS-CDMA) with an overloading factor (OF) of TWO has been evaluated with different levels of error in power control. The system model has been designed mainly for the uplink of the cellular CDMA over an additive white Gaussian noise (AWGN) channel. The effect of erroneous power control in the uplink of UCDS-CDMA costs a SNR of 1.1 dB, 1.3 dB and 1.6 dB as compared to the conventional perfectly power controlled underloaded CDMA (OF=1) with the power control error of 1 dB, 1.5 dB and 2 dB respectively at a BER of 10-3.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123862740","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}

For variable speed operation of wind energy conversion system, it is required to generate the maximum power at below the rated speed using an authentic and powerful control strategy. Wind speed has the major impact on the dynamics and control of wind turbines. But in practice there is no accurate measurement of effective wind speed available for direct measurement. In this paper a new technique is proposed for optimal power generation of wind turbine below rated speed without estimating the wind speed. An extended Kalman filter (EKF) is used to estimate the rotor speed and a proportional (P) controller is used to track the error between the measured and estimated rotor speed. The output of the P controller is the estimated aerodynamic torque. The estimated aerodynamic torque and the rotor speed act as an input to the aerodynamic torque feed-forward (ATF) controller. The output of the ATF controller is the generated torque. As the aerodynamic torque is highly dependent on the wind speed so it cannot be controlled. So we have to control the generated torque by using ATF for generating optimal power output. Finally the estimated outputs are validated through correlation analysis.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133272562","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}

Template matching based methods for obstacle tracking have been proposed in literature. These methods have limitations in tracking dynamic obstacles owing to scale and rotation variations. These variations arise due to relative velocity between the rover and the obstacle to be tracked. Due to the relative velocity, the correlation between the template of the obstacle and the region in the image corresponding to the obstacle in successive frames degrades. In this paper we present three schemes targeted at improving robustness of template matching based tracking technique using monocular vision. The algorithms presented account for the geometric constraints posed on an image captured from a fixed camera mounted on a mobile platform. We present experimental results comparing the performance of our technique with the existing template matching based techniques. Also, we present two real-time applications in the form of object following behavior and obstacle avoidance behavior to demonstrate its efficacy and computational feasibility.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129501439","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 sensor networks, energy consumption and bandwidth are the main factors that determine the lifetime of the sensors. In order to reduce the energy and bandwidth used in transmission, the proposed method uses Compressive sensing (CS) which can compress the input data in the sampling process efficiently. Since CS is more efficient for sparse signals, in this work, each sensor image is first decomposed into sparse and dense components. We have introduced Contourlet Transform for this decomposition because of its ability to capture and represent smooth boundaries of objects in images, so that the reconstructed images have a better quality. The reconstructed input images are fused using an adaptive algorithm based on NSCT in a centralized server. The improvement in the quality of the fused image is achieved by the use of an image fusion metric and a search algorithm to assign optimum weights to the various regions in the segmented source images. Experimental results show, no significant change in the quality of the fused images with and without compression. The results show that the proposed method achieves better visual quality and objective metrics than the state-of-art methods.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128366146","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}

Leakage causes economic loss in the form of wastage of water, damage to pipe networks and foundations of roads and buildings, and also poses risk to public health due to water contamination. The lost or unaccounted amount of water is typically 20-30 percent of production. Some older systems may lose even up to 50 percent. The water pipe networks in houses as well as public places are generally concealed and hence detecting water leakage in the initial stages before an upcoming damage is difficult. The existing technologies for detecting leakage have various limitations such as efficiency being dependent on size, material and depth of pipes, need for manual intervention, dependency on weather and surface conditions and effect of water pressure. In this paper, we propose an automated water leakage detection system using a wireless sensor network created along the distribution pipes based on thermal (IR) imaging. Thermal imaging has the capability to work in low lighting or dark conditions and helps in capturing the contrast between hot and cold areas created due to water leakage. A network of low cost, low power thermal imaging sensors each having its own processing and Radiofrequency (RF) Transreceiver units and operating independent of pipe, weather or surface conditions is proposed in this paper. A central database is updated on a real-time basis, enabling very early leakage detection and initiating subsequent action to address the problem. An example system evaluation is performed and results highlighting the power and cost impact of the sensor network system are presented.","PeriodicalId":374175,"journal":{"name":"2013 IEEE International Conference on Electronics, Computing and Communication Technologies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130892964","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}
