  • Selection of High Quality Path through MXAODV in Mobile Ad-Hoc Network   Order a copy of this article
    by Anupama Sharma, Abhay Bansal, Vinay Rishiwal 
    Abstract: Selection of high quality path in mobile ad-hoc network is a critical issue due to mobility of nodes and variable channel conditions during data transmission. Path containing smallest number of hops generally performs less due to some links on those paths may have low or marginal quality. Mean loss ratio of link is also not a perfect way to estimate link quality, mean channel condition is not realistic. Hence, link quality estimation on the basis of loss ratio in burst loss conditions of different channels is significant. Incorporation of loss variance for a link in its quality estimation through modified expected transmission count (mETX) is the main aim of the proposed protocol to improve the communication efficiency in mobile ad-hoc networks. This paper describes the design and implementation of proposed routing protocol named as modified expected transmission count enabled ad-hoc on-demand distance vector (MXAODV). Extensive simulation has been done to analyse the performance of MXADOV. Significant improvements found in terms of throughput, packet delivery fraction, normalised routing load and end-to-end delay.

  • Hybrid Genetic Algorithm for Task Scheduling in Distributed Real Time System   Order a copy of this article
    by Harendra Kumar, NUTAN CHAUHAN, Pradeep Yadav 
    Abstract: A distributed real time system consists of a set of heterogeneous processors located at possibly different sites and connected by a communication link. Task scheduling in distributed real time system attracts the attention of the researcher in many disciplines. Many researchers have been developed the solution of task scheduling problem by using different types of technique. In this paper, a hybrid genetic algorithm (HGA) is developed which is a combination of k-means and genetic algorithm to form the clusters of tasks in an effort to minimize the communication costs. A genetic algorithm is also developed to schedule the formed clusters of tasks onto set of processors to minimize the execution costs. The results of the algorithm have been compared with various existing techniques. Experiment results shows that the proposed algorithm achieves better efficiency than other existing techniques.
    Keywords: Task scheduling; distributed real time system; genetic algorithm; k-mean; system costs; response time.

  • Frequency Control of an Isolated Power System Considering Mutual Effects of AGC in Presence of Energy Storage Units   Order a copy of this article
    by MOUNICA MALLAREDDY 
    Abstract: Automatic Generation Control (AGC) of an isolated power system is investigated in this paper. Performance analysis is carried out by considering the mutual coupling effect between Load frequency control (LFC) and automatic voltage regulator (AVR) control loops by adding one fixed and one variable energy storage systems. The insertion of storage devices reduces the frequency oscillations for various load changes and also reduces the mutual effect of LFC and AVR. Simultaneous coordinated tuning of secondary controller and variable storage unit with Particle swarm optimization (PSO) and improved particle swarm optimization (IPSO) is carried out to provide control strategy for the system. System is simulated both in presence and absence of secondary controller in which IPSO gives better performance results than PSO. The simulation is carried out in MATLAB/SIMULINK software.
    Keywords: Load frequency control; Automatic voltage regulation; Mutual coupling of LFC and AVR; Energy storage systems; Power compensation by ESS.

  • A new PIDF Controller Structure for Delayed Process   Order a copy of this article
    by Bharat Verma, Prabin Padhy 
    Abstract: A new PID control structure (PIDF) for delayed processes is proposed in this paper. It consists of a derivative controller (D) in feedback with a standard Proportional-Integral (PI) controller. The proposed PIDF controller improves the robustness with respect to time delay and de-noising capability. The proposed controller is similar to a PI controller with a low pass filter in series, which minimises the effect of high-frequency measurement noise. The robustness of the proposed PIDF controller, with respect to the process-delay variation, is verified through simulation of four different processes and results are compared with standard PID controller. The parameters of PID and PIDF controller are tuned by minimising the ITSE objective function with the help of Genetic algorithm.
    Keywords: Robust Control; Linear Control; Dominant pole; PID controller; PIDF controller; Delayed process.

  • Design and Development of a Low Cost Mobile Phone Detector for Detecting Active Mobile Phones   Order a copy of this article
    by Thisura Meewella, Attaphongse Taparugssanagorn, Chantri Polprasert 
    Abstract: In this paper, we design and develop a low cost mobile phone detector which can detect active mobile phones near its vicinity in situations where mobile phones are kept turned ON or in silent mode. At the instant it detects Radio Frequency (RF) transmission signals from a mobile phone, the detector sounds a buzzer as well as blink a Light Emitting Diode (LED) indicating that it has detected an activated cell phone in its vicinity. Using this detector, it is possible to detect mobile phones used for unethical conducts, e.g., cheating during exams in an examination hall. Since the detector works even when the phone is in silent mode, it can be used to find a lost cell phone in instances when someone has misplaced their cell phone when it is in silent mode. This can also be used to detect mobile phones in private and confidential locations where some people use mobile phones to gather information about other people without their consent. Furthermore, this detector has the ability to distinguish the number of mobile phones active in its vicinity. To compare our detector with commercially available detectors today our detector delivers almost the same amount of performance accuracy at a much lower cost.

    by Bchira Saidi, Messaoud Amairi, Slaheddine Najjar, Mohamed Aoun 
    Abstract: This paper deals with a new design method of a fractional order PID controller for time-delay systems based on min-max numerical optimisation. The proposed design method uses a constrained optimisation algorithm to determine the unknown parameters of the controller. The main objective of the proposed method is to improve the transient time response, the stability margin, the robustness and the load disturbance rejection capability. All of these performances are tested through simulation examples.
    Keywords: constrained numerical optimisation; fractional PID; stability robustness; uncertainty; time delay system.

  • A survey on current and next generation aircraft collision avoidance system   Order a copy of this article
    by Debajit De, Prasanna Kumar Sahu 
    Abstract: To reduce the possibility of mid-air collisions, Federal Aviation Administration has developed the Traffic-Alert-and-Collision-Avoidance-System. TCAS is mandated worldwide on all large aircraft. In this paper, an overall description of the existing TCAS system is presented, followed by a detailed description of the system and its functional performance. The current collision avoidance system has been in operation for more than a decade. But major transformations to the National-Airspace-System are being implemented through FAA's Next-Generation-Air-Transportation-System in the coming years and that will require substantial modification to the existing system. The development of such new collision avoidance system which is Airborne-Collision-Avoidance-System-X has been pioneered. This survey article also describes the basic concept behind ACAS-X and briefly demonstrates how this new flexible approach in collision avoidance logic is fully compatible with NextGen airspace procedures and technologies. The aim of this work is to review, understand and compare the current and next generation aircraft collision avoidance system.
    Keywords: TCAS; Federal Aviation Administration; FAA; airborne collision avoidance system X; ACAS X; NextGen; TA & RA; unmanned aerial vehicle; UAV; general aviation.

  • A game theoretic model and a distributed admission control scheme for quality of service routing   Order a copy of this article
    by Paolo Conforto, Francesco Delli Priscoli, Alessandro Di Giorgio, Lorenzo Ricciardi Celsi 
    Abstract: In this paper, we present an innovative distributed quality of service routing scheme suitable to operate in networks of general topology implementing a Diff-Serv service model for QoS support. The proposed scheme is based on a game theoretic non-cooperative model which exploits, on the one hand, the topological information distributed within the network by the current (non-QoS) link-state and distance-vector routing protocols and, on the other hand, the QoS information locally available at the node where the forwarding process takes place. In order to guarantee the satisfaction of a stability condition at each node, a distributed admission control (DAC) scheme is proposed to jointly operate with the non-cooperative routing scheme. The DAC decides if a new flow can be accepted without violating the nodes' stability constraints and provides each node with cumulative information about the status of the network downstream from its outgoing links.
    Keywords: distributed admission control; DAC; Diff-Serv; game theory; Nash equilibrium point; quality of service routing; QoS.

  • A novel terminal sliding mode observer with RBF neural network for a class of nonlinear systems   Order a copy of this article
    by Amin Sharafian, Reza Ghasemi 
    Abstract: A novel scheme for designing a new observer with combining radial basis function neural network (RBFNN) and terminal sliding mode approaches is presented. Terminal sliding mode adopted to cover the effects of internal disturbances of the system and neural network handles the problem of uncertainties and unmodelled dynamics. Convergence of the observer error to zero and accurate estimation of uncertainties of the nonlinear system are the main advantages of the proposed observer. This observer is designed based on output injection method in which the error is injected to the next state in every step until it reaches the last state of the system. Eventually, the error is suppressed and converged to zero in the last state by applying RBFNN. The stability of neural network weights which are updated adaptively and the error dynamic are guaranteed by the Lyapunov theory. Finally, the simulation result shows the promising performances of the proposed observer.
    Keywords: RBFNN; state estimation; neural observer; nonlinear systems; terminal sliding mode observer; output injection.

  • Intelligent information passing about road transport using GSM and GPS   Order a copy of this article
    by Balamurugan Mohan, N. Karthik 
    Abstract: The main intention of this project is to find the accident spot and pass the location information to passenger's neighbours and also to the nearby police station and hospitals through the GPS and GSM networks. Nowadays, it becomes very difficult to know where an accident occurred and where to locate the vehicle. It is very difficult for the survival of the victim until anyone notices and provides the information to the nearby police station, hospitals and passenger's neighbours. If an accident occurs in remote areas, there will be no hope to survive. In this project, a programmed GPS/GSM module will incorporate a crash detector (vibrating sensor) which will report automatically to the nearby police station, hospitals, and passenger's neighbours. The information shares the location of the accident via GSM communication platform (using SMS messaging). This will allow a quick and early response and rescue of victims of the accident; saving lives and properties. The paper reports its experimental results, with appropriate conclusions and recommendations.
