Abstract

How to collect information optimally by scheduling a limited number of sensors is one of the key technologies of safety monitoring for large mechanical equipment systems. In this paper, an improved model of Pulse Coupled Neural Network is used for the discretization algorithm of continuous features. And based on classificatory error parameter and approximate dependence degree in Variable Precision Rough Sets theory, a VPRS data model is created by utilizing the measured signals from the multi-sensor Bridge Erecting Machine Safety Monitoring System. Then the corresponding relations between time-frequency characteristics and operating condition classifications are analyzed. Finally, while the determinability of decision making analysis is enhanced, the validity order of safety monitoring information of the multi-sensor sampling points is gained, which can direct optimal scheduling of position of sensors in large-scale mechanical equipment systems. DOI: http://dx.doi.org/10.11591/telkomnika.v10i8.1634

Abstract

Bioprocesses have the inherent characteristics of high nonlinearity, parameter uncertainty and information imperfection. These specific natures may cause some difficulties in control. Jacobian linearization method was used in this paper to linearize the bioreactor model firstly, and then a Multiple-input and single output (MISO) model predictive controller was designed for the reactor. PID controller and fuzzy-PID controller was also introduced to compare with the MPC controller. Simulation results prove that the model predictive control has several advantages over the other controls for bioreactors. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1444

Abstract

With increasing research and advancement in solid-state power electronic devices and microprocessors, various inverter control techniques employing pulse width modulation (PWM) are becoming popular especially in AC motor drive applications. The most commonly used techniques are sinusoidal PWM (SPWM) and space vector modulation PWM (SVPWM). SVPWM is considered to be superior to the SPWM because of better DC bus utilization. In this paper, a real-time digital implementation of SVPWM algorithm for three-phase two level inverter using dSPACE DS1104. The results obtained from the experimentation are closer to that of simulation, which confirms the validity of the implemented algorithm.

Abstract

Wireless sensor network (WSN) consists of a small size sensor nodes depends on battery power. Applications of sensor networks are street lighting, home automation, industrial plant, environmental parameters, health care and military. Security is becoming a major concept in the design of wireless sensor networks. Attacks on sensor networks include attack on confidentiality, integrity and availability. Lack of confidentiality means that the secret information is revealed to attackers. Lack of integrity means that the attacker modifies the contents (data) communicated in the sensor network. Lack of availability means the resources in the network is not available to authorized users. So to avoid these problems we need better security measures. In this paper we are dealing with intrusion detection. Intrusion detection plays an important role in the design of wireless sensor networks. An intruder can perform various attacks like replay, interception, worm hole, sink hole attacks. So our aim in this paper is to find such intrusions as early as possible, when they occurred and to enhance the life tome of the sensor network. This is because sensors nodes depend only on battery power. Our intrusion detection is based on clustering of the sensor network. This makes routing process, medium control and intrusion detection simple. DOI:  http://dx.doi.org/10.11591/telkomnika.v15i1.8072

Abstract

Simulation earthquake shaking table tests on the system of ultra high-voltage electrical equipment mounted on pedestals are carried out in order to study the dynamic amplifying effect of the pedestal in the system. The relationship between the dynamic responses of the system and main influence factors is studied by means of changing frequencies or stiffness and masses of the system under the driving function of several different earthquake waves. The studied results show that the dynamic amplifying effect of the pedestal in the system or the pedestal amplifying coefficient has close relationship with the stiffness and masses distributing or the frequencies of the system. Some regular and universal conclusions are obtained, and the suggested scale on the dynamic amplifying coefficient of the pedestal in the system is put forward, which provides reference for future design and engineering application on the ultra high-voltage electrical equipment with pedestal. DOI: http://dx.doi.org/10.11591/telkomnika.v10i8.1647

Abstract

Cloud data security is one of the major and crucial concern in everyday life. Now a days cloud computing is emerging as vast and fastest growing technology depending on the usage. Cloud computing does not allow to keep data at user site and thus a data security is concerned to be a major challenging task regarding data storage. This paper overall describes the monitoring of the cloud data concerning data storage. In this paper we proposed a new methodology that can efficiently managed the security to the data and provide privacy to the consumer using the services of the cloud. Our proposed technique provides data security by using the third party monitoring system which acts as an interface between the cloud consumer and cloud owner. Basically third party monitors the each and every activity of the cloud consumer and based upon his performance he respond to the cloud owner for taking decision. Our proposed concept provides the security from consumer point of view and owner side of view making the flexibility to the cloud infrastructure. Existing work focus mainly on security from owner side of view that not well fitted into the lifecycle of data security.

Abstract

Some chaos-based image encryption schemes using plain-images independent secret code streams have weak encryption security and are vulnerable to chosen plaintext and chosen cipher-text attacks. This paper proposed a two-level secret key image encryption scheme, where the first-level secret key is the private symmetric secret key, and the second-level secret key is derived from both the first-level secret key and the plain image by iterating piecewise linear map and Logistic map. Even though the first-level key is identical, the different plain images will produce different second-level secret keys and different secret code streams. The results show that the proposed has high encryption speed, and also can effectively resist the existing cryptanalytic attacks. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1599

Abstract

Heterogeneous wireless sensor networks (HWSN) gathers information from a cooperative network. In HWSN, the sensor nodes are scattered and the major challenges are topology control, battery optimization, packet loss and link lifetime. The existing techniques do not concentrate on all the mentioned issues. The objective of this work is to provide congestion-free data transfer with higher throughput and increased packet delivery ratio. In the proposed methodology, three protocols are designed and developed, namely, hop by hop rate adjustment protocol (HHRA), energy efficient data transfer protocol (EEDT) and alternative routing congestion control protocol (ARCC). The HHRA protocol senses the traffic in the channel and adjusts the transmission rate accordingly to avoid congestion. Secondly, the EEDT protocol is used to find specific nodes that are more efficient and transfer packets through those nodes to improve throughput. The ARCC protocol is used to redirect the path of transmission during the occurrence of congestion. Thus, the proposed traffic contention and control mechanisms ensures congestion free transmission and increases the packet delivery ratio by 23% and average throughput by 20% compared to the dynamic contention window based congestion control (DCWCC) algorithm.
