Lionel Nkenyereye,Jong-Wook Jang 한국정보통신학회 2016 2016 INTERNATIONAL CONFERENCE Vol.8 No.1

A billion of objects can sense, communicate and share information, interconnected over Internet Protocol (IP) networks. However, transmission of data collected by these objects gives rise to a large volume of data. Thus, large internet services must deal with concurrency of billions of objects connect to internet. High traffic demands of sessions initiated by these objects should challenge system design of web services. This paper studies design functionalities to an Internet of Things applications based cloud computing should have. The design consists of defining components of management service in Internet of Things. Therefore, these components are based on the Node.js, a web server architecture based on event loop approach and Hadoop platform responsible of analyzing data regularly collected. The proposed management service based architecture is useful for handling concurrent sessions as the number of objects connects to the Internet services grow and renders the processing information possible through MapReduce framework based analytics.

Addressing Concurrency Design for HealthCare Web Service Gateway in Remote Healthcare Monitoring System

Lionel Nkenyereye,Jong-Wook Jang 한국인터넷방송통신학회 2016 Journal of Advanced Smart Convergence Vol.5 No.3

With the help of a small wearable device, patients reside in an isolated village need constant monitoring which may increase access to care and decrease healthcare delivery cost. As the number of patients’ requests increases in simultaneously manner, the web service gateway located in the village hall encounters limitations for performing them successfully and concurrently. The gateway based RESTful technology responsible for handling patients’ requests attests an internet latency in case a large number of them submit toward the gateway increases. In this paper, we propose the design tasks of the web service gateway for handling concurrency events. In the procedure of designing tasks, concurrency is best understood by employing multiple levels of abstraction. The way that is eminently to accomplish concurrency is to build an object-oriented environment with support for messages passing between concurrent objects. We also investigate the performance of event-driven architecture for building web service gateway using node.js. The experiments results show that server-side JavaScript with Node.js and MongoDB as database is 40% faster than Apache Sling. With Node.js developers can build a high-performance, asynchronous, event-driven healthcare hub server to handle an increasing number of concurrent connections for Remote Healthcare Monitoring System in an isolated village with no access to local medical care.

Software Defined Network (SDN) and edge computing are emerging technologies in information and communication technology to minimize data collection latency on the Internet of Vehicles (IoV). The car has the potential to contribute to the development of smart cities by accessing urban data that are collected and reported to a remote data centers through wireless communication This paper presents the study on intelligent transport data collection strategy in a Software- Defined Edge vehicular networking. The two sensing data collection schemes are cooperative vehicular and edge prediction mode based Software Defined Vehicular Network (SDVN). We prove that urban data collection cost through a novel algorithm called car sensing platform for urban data collection algorithm to find an optimal strategy. We set up a simulation scenario based on realistic traffic and communication features and demonstrate the scalability of the proposed intelligent transport data collection strategy. It can be seen that the edge cell predictive trajectory decision-based SDEVN mode scheme reduces greatly the cost when the road seems to have a high number of the vehicle.

Performance Evaluation of Node.js for Web Service Gateway in IoT Remote Monitoring Applications

Nkenyereye, Lionel,Jang, Jong-Wook The International Promotion Agency of Culture Tech 2016 International Journal of Advanced Culture Technolo Vol.4 No.3

The growth of mobile devices in Internet of Things (IoT) leads to a number of remote and controlling system related IoT applications. For instance, home automation controlling system uses client system such web apps on smartphone or web service to access the home server by sending control commands. The home server receives the command, then controls for instance the light system. The web service gateway responsible for handling clients' requests attests an internet latency when an increasing number of end users requests submit toward it. Therefore, this web service gateway fails to detect several commands, slows down predefined actions which should be performed without human intervention. In this paper, we investigate the performance of a web server-side platgorm based event-driven, non-blocking approach called Node.js against traditional thread-based server side approach to handle a large number of client requests simultaneously for remote and controlling system in IoT remote monitoring applications. The Node.JS is 40% faster than the traditional web server side features thread-based approach. The use of Node.js server-side handles a large number of clients' requests, then therefore, reduces delay in performing predefined actions automatically in IoT environment.

Design of Environmental Monitoring system Based on Push-based synchronization and XMPP PubSub architecture

Lionel Nkenyereye,Jong-Wook Jang 한국정보통신학회 2017 2016 INTERNATIONAL CONFERENCE Vol.9 No.1

A Novel method using Extensible Messaging and presence Protocol (XMPP) was proposed to design environmental monitoring system. Synchronization approaches are based on a pull method, a push method, or a hybrid of both. In this paper, we present an approach builds on pushing change notifications and pulling changed in the intelligent building controls units responsible of sending measurement of sensors integrated on them. When the sensor’s value is updated or more one changed, the intelligent control units send a content ping to a XMPP server considered as a hub service (gateway) using XMPP PubSub protocol. The hub service then retrieves the sensor’s value from intelligent building controls units and consecutively uses XMPP PubSub protocol to push to destination’s user devices. Upon receipt of a notification, the user wherever he is, may decide to obtain the changed sensor’s values. With this push-based synchronization, IoT will enable all the communication devices to push the data generated by or associated with devices or objects globally accessible.

Push-based synchronization using XMPP PubSub architecture for disseminating IoT data

Lionel Nkenyereye,Jong-Wook Jang 한국정보통신학회 2017 2016 INTERNATIONAL CONFERENCE Vol.9 No.1

Growth in social networking, smartphone applications, and the Internet of Things (IoT) has resulted in the Internet primarily being used as an information distribution network. This rooted in the recognition that data from IoT devices is the foundation for smart Home. Synchronization approaches are based on a pull method, a push method, or a hybrid of both. In this paper, we present an approach builds on pushing change notifications and pulling changed in the intelligent building controls units responsible of sending measurement of sensors integrated on them. When the sensor’s value is updated or more one changed, the intelligent control units send a content ping to a XMPP server considered as a hub service (gateway) using XMPP PubSub protocol. The hub service then retrieves the sensor’s value from intelligent building controls units and consecutively uses XMPP PubSub protocol to push to destination’s user devices. Upon receipt of a notification, the user wherever he is, may decide to obtain the changed sensor’s values. In order to make this possible, destination’s user have previously subscribed to the hub service and have indicated which IoT data are interested to be notified. With this push-based synchronization, IoT will enable all the communication devices to push the data generated by or associated with devices or objects globally accessible.
