Smart Monitoring of Sensor Behavior in WSN
[attachment=25036]
Abstract
WSNs are emerging as a new paradigm, gathering information in a collaborative way, where independent sensor nodes collect and share information. In the last few years ubiquitous computing popularity has grown considerably, ambient intelligence and home automation systems are having a good public acceptance. In this context, I developed a mobile application to remotely monitor one WSN, installed at a customer's home. The application's main goal is to interact with a WSN, allowing a user to consult sensor states and receive sensor alerts.
INTRODUCTION
Due to the growth of potential of Wireless Sensor Networks (WSN), now becomes possible to use this technology in various new generation services such as monitor environment characteristics like temperature, humidity, among others. There are many next generation services that use this technology, since this type of networks has broad applicability .The quick and fast increasing development of low power wireless communication devices and microprocessors, in conjunction with the significant progress in the protocols for Ad-Hoc networks and pervasive computing, permitting the application of WSN in various areas, from industrial to home automation [1] [2].
RELATED WORK
To the best of our knowledge, there are no mobile applications with the functionality offered by our proposed solution. Much of the research is still focused on the implementation of the WSN and not in the interaction with such networks via mobile devices. During our research we found only one mobile application related to WSNs, based on a three-dimensional representation of the area covered by the WSN. The main goal of vsiogap3d project is to (and I quote) “develop an application that presents a three-dimensional model of a building. It should also connect to the data repository and download building sensor information such as temperature and lighting conditions in individual rooms” [4]. Thus, the proposed approach turns out to be a pioneer in the remote interaction with the WSN via a mobile device.
PROPOSAL APPROACH
In this section, I developed a mobile application that allows users to query the state of a WSN anytime, anywhere. To this end, there is a need to link some essential components, such as a WSN and a proper interaction application, an Internet connection, a Control Station with the proper Web Services, a relational Data Base and finally a mobile device. This section presents the general architecture of the proposed solution, showing the relationship between the various components, as we can see in figure 1.
CONCLUSION AND FUTURE WORK
The market for mobile devices is growing and in the future, all mobile devices will have Internet access. This way it is possible to develop mobile applications that can take advantage of the Internet, and improve the quality of future applications.
The main contributions of this project are the concept of interacting with a WSN and remotely monitor the state of all sensor nodes, through a mobile application.
Tests were performed with the use of a prototype and reveled that the developed solution successfully interacted with the WSN and the evolved components. It proved that is possible to remotely interact and monitor a WSN through a mobile application. Using the application a user is notified if an event is detected in WSN, being also possible to check the status of the WSN from any location, requiring only an Internet connection.
