In this paper, we present a design of a multi core embedded system model of a self diagnostic system for industries developed over a Wireless sensor Network. In this design, the system is segmented into multiple clusters, each representing a Wireless node, and controlled by a 'core', which is an independent microcontroller based local system. To demonstrate our system, we have developed a design consisting of two clusters viz. 'critical' and 'non-critical' clusters each consisting of sensors with varying priorities in the fault diagnostic process. Withthis paper, we try to present the work done in the partial development of the said system. the paper outlines and details the development of the non critical cluster consisting of a single sensor which is RPM sensor, and its successful implementation as a fault diagnostic module.

A novel and unified approach for reliable distributed and parallel computing using mobile agents is introduced. the agents can be deployed in large scale and hierarchical network environments crossing barriers transparently. the networks can consist of high- and low-resource nodes ranging from generic computers to microchips, and the supported network classes range from body area networks to the Internet including any kind of sensor and ambient network. Agents are represented by mobile program code that can be modified at run-time. the presented approach enables the development of sensor clouds and smart systems of the future integrated in daily use computing environments and the Internet. Agents can migrate between different hardware and software platforms by migrating the program code of the agent, embedding the state and the data of an agent, too. the entire information exchange and coordination of agents with other agents and the environment is performed by using a tuple space database. Beside architecture specific hardware and software implementations of the agent processing platform, there is a JavaScript (JS) implementation layered on the top of a distributed management layer. the JS platform enables the integration of Multi-agent systems (MAS) in Internet server and application environments (e. g., WEB browser). Agents can migrate transparently between hardware-level sensor networks and WEB browser applications or network servers and vice versa without any transformation required. (C) 2015the Authors.

Wireless sensor Networks (WSNs) are increasingly implemented in different area of applications. It is possible that the data collected by adjacent nodes can be redundant due to large numbers of nodes in these networks, so aggregation of data should be exploited for Energy conservation in WSNs. It is very important to transmit the aggregated data to the sink node or base station effectively and reliably. Here, DRINA (Data routing for in-network aggregation) algorithm is studied. It uses data aggregation as key point and reliably route data using a fault-tolerant routing mechanism.

this paper deals with a project for real-time monitoring of railway tracks to detect events, such as fast failures from natural risks, which may threaten the transit of trains. the paper describes a network of smart sensors for early warning of these endangering events. three main types of fast-failure events involving railways were identified: sinkhole, rock and debris falls. A case study on a known test site and experimentation with various scenarios were carried out with a view to developing algorithms capable of spotting and localising them. Results demonstrate the good performance of the network in monitoring the investigated events.

Advances in communication, information technology, and computation have led to a rapid change of today's world. Actuation, communication, sensing, and control are becoming ubiquitous. While this offers many possibilities Smart cities, Smart buildings. Smart devices, Smart factories, Smart health monitoring a smarter world there are also several challenges which need to be tackled. How can one handle the increasing complexity? Can one guarantee safety and performance of such networked control systems subject to erroneous communication, delays, and failures of sensors and actuators? Is it possible to design control systems with plug and play capacity? How can one guarantee privacy of the controlled subsystems while exchanging information? Predictive control is a well suited control approach to tackle some of these challenges, since its allows to directly take constraints, preview information, as well as models of the physical world into account. We limit our attention to three areas we believe predictive control methods can have a significant impact: the efficient and easy implementation of predictive control on the omnipresent embedded computation hardware, the control under resource limitations and network effects, and the control on the network level, outlining a contract based control approach which allows a structured, yet flexible hierarchical design. We briefly review results from these fields and outline some solutions related to our work, that provide possible solutions to the considered challenges.

Ubiquitous computing offers enhanced interactive, human-centric experiences including sporting and fitness-based applications. To enhance this experience further, we consider augmenting dodgeball by adding digital elements to a traditional ball game. To achieve this, an understanding of the game mechanics with participating movable bodies, is required. this paper discusses the design process of a ball-player-centric interface that uses live data acquisition during gameplay for augmented dodgeball, which is presented as an application of augmented sports. Initial prototype testing shows that player detection can be achieved using a low-energy wireless sensor based network such as that used with fitness sensors, and a ball with an embeddedsensor together with proximity tagging.

Presently industrial automation is growing rapidly emphasizing on centralized monitoring and independent control of sub-systems. this increases the number of remote sub-systems, which need intermediate communication. Another challenges observed are the reduction of system size and the maintenance cost with flexibility in operation. Regulatory, repetitive sequential control and interlocking are the typical mandatory requirements for batch execution and safety. this paper presents development and analysis of prototype system for wireless controlling and monitoring of the batch process experimental set-up. It proposes the efficient utilization of ARM micro-controller for the real-time monitoring and control of temperature and level. A graphical user interface using Visual Studio. NET is developed to operate the plant remotely. this facilitates the user to control, supervision and data acquisition through wireless communication between laboratory set-up and user interface via ZigBee protocol. Sensitivity and linearity analysis of RTD output and ultrasonic level sensor output is carried out citing fair linearity of RTD and level sensors calibration. Additionally errors in calculated and observed output at ADC are also investigated. the normal operation and safety interlocks have been identified, executed & validated to mitigate the hazardous events in plant considering the possibility of failure of temperature and level sensors. the proposed system is developed successfully and works in defined manner with overall satisfactory performance.

Due to the fast evolution of wireless access networks and high-performance mobile devices together withthe spreading of wearable medical sensors, electronic healthcare (eHealth) services have recently started to receive more and more attention, especially in the mobile Health (mHealth) domain. the vast majority of mHealth services require strict medical level Quality of Service (QoS) and Quality of Experience (QoE) provision. Emergency use-cases, remote patient monitoring, tele-consultation and guided surgical intervention require real-time communication and appropriate connection quality. the increasing significance of different overlapping wireless accesses makes possible to provide the required network resources for ubiquitous and pervasive mHealth applications. Aiming to support such use-cases in a heterogeneous network environment, we propose a network-assisted intelligent access point selection scheme for ubiquitous applications of Future Internet architectures focusing on real-time mobile telemedicine services. Our solution is able to discover nearby base stations that cover the current location of the mobile device efficiently and to trigger heterogeneous handovers based on the state and quality of the current access network. the solution is empirically evaluated in Wi-Fi networks used by real-life Android mobile devices and we observed that the scheme can improve the quality of mHealth applications and enhance traffic load balancing capabilities of wireless architectures.
