Specific Project

Standard protocols for reliable data transmission over unreliable channels are based on various Automatic Repeat reQuest (ARQ) schemes, whereby the sending node receives feedback from the receiver and retransmits the missing data. We discuss this issue in the context of one-way data transmission over simple wireless channels characteristic of many sensing and monitoring applications. Using a specific project as an example, we demonstrate how the constraints of a low-cost embedded wireless system get in the way of a workable solution precluding the use of popular schemes based on windows and periodic acknowledgments. We also propose an efficient solution to the problem and demonstrate its advantage over the traditional protocols.

Software And Hardware

To tackle such problems as low security, inefficiency and high cost in traditional data transmission between different security domains, this paper discussed the basic design decisions that form the first step one should consider, especially for creating a design with the advantage of high-efficiency and low-cost optical devices. It first explored the design issues of software and hardware systems with the application of various network separation systems. It then described the reliability features with regard to error detection and data integration, and the mechanism of the newly defined protocol structure. At last, it outlined the key design points for the system implement and measurement.

The Impact

In the article the analysis of methods and means of ensuring the noise immunity transmission in telecommunication networks that use technologies in real time to ensure quality, valid and reliable data transmission under conditions of interference. For telecommunication networks the problem of optimal quality reception of information is to use the properties of the useful signal, interference, and transmission channel to increase the probability of correct reception. To increase the probability of correct reception needs to be pre-processed received signal that increases the signal interference. Transmission channels that use technologies that allow real-time to ensure quality, valid and reliable data transmission under conditions of interference provide better instruction indicators reliable transmission of information is carried out through the use of the necessary coding. During transmission on such channels, there are many difficulties associated with the impact of natural, industrial, intentional and unintentional interference. All methods of a noise stability in General lead to temporal and hardware redundancy as part of the source of information and of the addressee. Examine noise immunity of TCN as ability of the system to counteract to the hindrances, then it is necessary to know, what to counteract and on what to counteract, for a fight against hindrances a priori information is needed about properties of transmitter of information and about hindrances. Knowing all these properties of the signal and noise, it is possible to establish certain differences between them and use them to develop ways, means and methods to provide noise immunity. The aim of this article is realization of analysis of methods and backer-ups of interference immunity information transfer in TCNS, which will allow real-time to guarantee the quality, reliable and reliable transmission of the hindrances given in the conditions of influence. Unlike distortions hindrances carry casual character. They in are good time unknown and that is why cannot be fully removed. Knowledge of methods and facilities of construction of modern channels of transmission TCN in the conditions of action of hindrances, will allow building the reliable channels of information transfer for such networks.

Plant Monitoring

Wireless Sensor Networks (WSNs) are used in almost every sensing and detection environment instead of wired devices in the current world, all the more in power plant monitoring applications. In such a kind of environment, providing reliability is a challenging task, since WSN makes use of low powered sensors. There are many existing works that provide reliable transmission in WSN (predominantly via multipath routing). However, most of the existing works take additional delay, excessive packet loss, and energy consumption, and hence they provide less packet delivery and throughput. Adaptive Priority Routing (APR) is first proposed during the initial design to provide efficiency in next hop selection. APR computes the priority value for selecting the intermediate nodes during the data transmission in order to improve the packet delivery, throughput, and energy efficiency. In addition to this, APR is developed into QAPR protocol to provide reliability which can operate in two modes,Drepresenting distance mode andQrepresenting quality of service (QoS) mode. The proposed work is simulated in both flat topology and hierarchical topologies and the simulation analysis shows that the reliability is increased significantly in comparison with existing works.

Successful Case

The development of structural health monitoring (SHM) systems and their integration in actual structures has become a necessity as it can provide a robust and low-cost solution for monitoring the structural integrity of and the ability to predict the remaining life of structures. In this review, we aim at focusing on one of the important issues of SHM, the design, and implementation of sensor networks. Location and number of sensors, in any SHM system, are of high importance as they impact the system integration, system performance, and accuracy of assessment, as well as the total cost. Hence we are interested in shedding the light on the sensor networks as an essential component of SHM systems. The review discusses several important parameters including design and optimization of sensor networks, development of academic and commercial solutions, powering of sensors, data communication, data transmission, and analytics. Finally, we presented some successful case studies including the challenges and limitations associated with the sensor networks.
