EATDDS: Energy-aware middleware for wireless sensor and actuator networks

According to Object Management Group organization, Data Distribution Service (DDS) middleware is the leading technology for Industrial Internet of Things (IIoT). Therefore, using DDS-based middleware for Wireless Sensor/Actuator Networks (WSAN) will extremely ease the development and integration of WSAN applications into IIoT, which has an effective impact on improving the productivity and saving the cost. However, applying such technology over WSAN significantly affects the energy consumption. In this work, an energy-aware middleware for WSAN is developed based on DDS standard, which is called EATDDS. Furthermore, developing this middleware leads to a major enhancement into TOSSIM simulator; in which an Online Energy Model (OEM) is developed to make TOSSIM capable of developing and testing energy-aware protocols. The model is validated by comparing it against POWERTOSSIM. Our results show that EATDDS is efficient and can be accommodated with limited system resources.

Improvement of an Interoperable and Adaptable Middleware using IoT Semantic Web Technologies

In today changing world, Internet of Things (IoT) is creating a new world, where people and businesses can make more timely and better informed decisions about what they want or need to do. Over the last years, agriculture industry in few countries has been expended to smart agriculture. Nevertheless, the agricultural industry in Myanmar needs to be modernized with the involvement of IoT technologies for crops’ growth monitoring, irrigation decision and harvesting system. However, due to the complexity of IoT middleware, most of the middleware frameworks are designed to be used by IT experts. To allow non-IT experts (e.g. farmers, plant scientist) to configure the sensor devices easier and faster, without knowing the background knowledge of technical details, sensor-level configuration of heterogeneous devices needs to be fully interoperable (network, syntactic, and semantic interoperability) due to the huge number of sensor devices integrated and their diversity in term of data formats, communication protocols, nature of components etc. In this work, we propose a fully interoperable middleware framework that incorporates semantic web technologies with the existing Global Sensor Network middleware to solve the above challenges. The proposed system supports horizontally semantic interoperability which addresses the challenge of adaptability of our approach to different domains. Performance of the proposed system will be implemented and evaluated mainly in crops’ growth of agriculture area of Myanmar.

A Highly Accurate Deep Learning Based Approach for Developing Wireless Sensor Network Middleware

Despite the popularity of wireless sensor networks (WSNs) in a wide range of applications, security problems associated with them have not been completely resolved. Middleware is generally introduced as an intermediate layer between WSNs and the end user to resolve some limitations, but most of the existing middleware is unable to protect data from malicious and unknown attacks during transmission. This paper introduces a secure wireless sensor network middleware (SWSNM) based on an unsupervised learning technique called generative adversarial network algorithm. SWSNM consists of two networks: a generator (G) network and a discriminator (D) network. The G creates fake data that are similar to the real sample and combines it with real data from the sensors to confuse the attacker. The D contains multi-layers that have the ability to differentiate between real and fake data. The output intended for this algorithm shows an actual interpretation of the data that is securely communicated through the WSN. The framework is implemented in Python with experiments performed using Keras. Results illustrate that SWSNM algorithm improves the accuracy of the data and enhances its security by protecting data from adversaries. In addition, the SWSNM algorithm consumes significantly less energy, has higher throughput, and lower end-to-end delay when compared with a similar conventional approach.

Node/Proxy portability: Designing for the two lives of your next WSAN middleware

Middleware for wireless sensor and actuator networks (WSANs) provides powerful programming abstractions which simplify application development. While it is highly desirable to reuse WSAN middleware across a wide range of hardware platforms, in practice, complex middleware may not fit in nodes with limited resources. As one possible solution, we propose the so-called proxy approach: the middleware is ported on a general purpose computer, from where the sensors and actuators of the resource-constrained nodes are accessed remotely yet in a way that is transparent to the application, which runs unmodified, as if it resided on the physical nodes. We provide design guidelines and a middleware transformation process for implementing the proxy approach in a structured way. We also present a concrete implementation of the proxy approach for our own middleware, along with a performance evaluation of the proxy software environment in a wired testbed with almost 200 sensor nodes.

Architecting Publish/Subscribe-Based Middleware for Wireless Sensor Networks

Middleware for wireless sensor networks (WSNs) can help bridge the gap and remove impediments. Publish/Subscribe (P/S) is an asynchronous communication paradigm that supports many-to-many interactions between a set of clients. P/S paradigm is a suitable paradigm for WSNs middleware. This paper designs PSWSN, a WSNs middleware, whose architecture is composed of service management, P/S support and access management. Service management is an information publishing platform based on B/S mode, its main function is to abstract the various business functions into services. P/S support in PSWSN is a core and supports publishing and matching services. Access management is employed so that WSNs can be abstracted and accessed as logical rather than individual physical entities.

절전제어를 위한 사용자 감성마진 적용 능동규칙시스템

Abstract In this paper, we propose the active rule system applying with emotional margin for power saving control. The proposed system in this paper is a part of the system which derives smart power saving by adjusting the illuminance using active rules within compromising the user’s emotion. For this, we set the specific range of standard illuminance and the lower bound of user’s emotional margin of illuminance based on measurements and analysis, and use these data in design of active rules. And then, we design and implement the active rule system using mobile agent. The mobile agent in the proposed system migrates to the destination sensor nodes, acquires and transmits sensor data according to the purpose and needs through the active rules, and directly executes the actions corresponding to the optional events(changed sensor data and/or time etc.). And then, we show the potential applicability of the proposed active rule system in various active sensor network applications through the interaction with the rule base and mobile sensor network middleware system.

Reconfigurable Publish/Subscribe Middleware for Wireless Sensor Networks

This paper presented a approach, called LBS, for modeling and implementing the architecture of wireless sensor networks (WSNs) publish/subscribe (Pub/Sub) applications using a local broker subcomponent (LBS) model. Considering the reconfigurability of WSNs applications which was necessary for WSNs middleware, a graph oriented local broker subcomponent (GOLBS) model was defined based on the LBS model by integrated WSNs middleware with Pub/Sub. The analysis indicated that GOLBS provided reconfiguration management and non-predefined dynamic reconfiguration management for WSNs middleware. The results imply that GOLBS can easily be constructed, while ensuring good reconfigurability.

Design and Implementation of Middleware for Wireless Sensor Networks

Middleware supports programming abstract which facilitate the programmer task and bridge the gap between the application and the hardware. Middleware for wireless sensor networks (WSNs) can help bridge the gap and remove impediments. This paper designs GWSN, a middleware WSNs, whose architecture is composed of runtime support, application development kits, and software development kits. Runtime support in GWSN is the core of WSNs middleware and supports executing and maintenance of WSNs applications. Application development kits includes many basic function kits, such as display editor, rule editor, and workflow editor, which support the application development of WSNs. Software development kits provides easy-to-use application programming interface.

A distributed middleware for self-configurable wireless sensor networks

Heterogeneity, mobility, and resource constraints are the inherent features of the wireless sensor network. In addition, for the wireless sensor network development, the developers have to design the low-level system details adaptive to specific upper layer non-compatible protocols. The distributed services are a middleware, which can make large-scale and resource-constrained wireless sensor network adapt to the dynamic environment in an effective way. It can not only guarantee transmission quality, but also can make application development simple and efficient. In the distributed services, the composition service deals with the dynamics efficiently by managing the nodes to form and maintain task-oriented groups, which not only increases the degree of transparency to the applications, but also improves the reliability and energy efficiency. The entire process releases developers from the tedious low-level work. In this paper, we focus on the demonstration of composition service and its achievement for the self-configurable wireless sensor network.

A service-integrated sensor network middleware applied to industrial solutions of IoT related

With the deployment and application of Internet of Things, middleware for sensor network has become an increasingly important factor to facilitate the programmer task and bridge the gap between the applications and the underlying infrastructure. Most existing middleware for sensor networks lack attention for integrating services into a generic architecture and present inflexibility that make them useless in the context of industrial solutions of Internet of Things. To solve this problem, we proposed a new middleware deployment model and present layered and distributed architecture utilizing our "Ends to the Middle" approach. Actual application of middleware demonstrates that our proposed architecture is highly modular and efficient, offers good performance in complex application scenarios of Internet of Things.

PS-QUASAR: A publish/subscribe QoS aware middleware for Wireless Sensor and Actor Networks

It has been more than 30 years since the first research into Wireless Sensor and Actor Networks appeared. However, WSANs are still not a ubiquitous technology due to several factors which include a lack of Quality of Service (QoS) support or the absence of high level programming models. New applications with heterogeneous QoS requirements where WSANs can be successfully applied, such as Critical Infrastructure Protection (CIP), have been recognized.PS-QUASAR, a middleware for WSANs that deals with these two issues, offers a high level simple programming model based on the publish/subscribe paradigm. In this model all nodes in the network are potential publishers of each of the topics. PS-QUASAR also handles QoS (reliability, deadline, priority) and supports a many-to-many exchange of messages between nodes in a fully distributed way by means of multicasting techniques. Performance evaluation via simulation using the Contiki operating system shows that the protocol can handle multiple publishers and subscribers at the same time whilst dealing with QoS requirements.

Event-based middleware for healthcare applications

In existing middleware for body sensor networks, energy limitations, hardware heterogeneity, increases in node temperature, and the absence of software reusability are major problems. In this paper, we propose an event-based grid middleware component that solves these problems using distributed resources in in vivo sensor nodes. In our multi-hop communication, we use a lightweight rendezvous routing algorithm in a publish/subscribe system of event-based communication. To facilitate software reuse and application development, a modified open services gateway initiative has been implemented in our middleware architecture. We evaluated our grid middleware in a cancer treatment scenario with combined hyperthermia, chemotherapy, and radiotherapy procedures, using in vivo sensors.

Experimental Performance Evaluation of POBICOS Middleware for Wireless Sensor Networks

The advances in the theory of wireless sensor networks have been remarkable during the past decades, but there is a lack of extensive experimental evaluations. In this paper we present performance-evaluation methods and results for POBICOS (platform for opportunistic behaviour in incompletely specified, heterogeneous object communities), which is an advanced middleware for wireless sensor networks (WSNs). The measurements concern energy consumption, duty cycle, and OS task profiling as well as communication characteristics such as round trip time (RTT) and throughput. In addition, a bandwidth analysis during a long-term experiment of fully functional POBICOS network and application is studied. Based on the evaluation results, power mode and data cache improvements are presented as well as CPU clock frequency optimizations.

Middleware for wireless sensor networks: an outlook

Abstract In modern distributed computing, applications are rarely built directly atop operating system facilities, e.g., sockets. Higher-level middleware abstractions and systems are often employed to simplify the programmer’s chore or to achieve interoperability. In contrast, real-world wireless sensor network (WSN) applications are almost always developed by relying directly on the operating system. Why is this the case? Does it make sense to include a middleware layer in the design of WSNs? And, if so, is it the same kind of software system as in traditional distributed computing? What are the fundamental concepts, reasonable assumptions, and key criteria guiding its design? What are the main open research challenges, and the potential pitfalls? Most importantly, is it worth pursuing research in this field? This paper provides a (biased) answer to these and other research questions, preceded by a brief account on the state of the art in the field.
