Monitoring Status of Objects at Home or Office Using Machine to Machine Network Rajeev Kumar Piyare, Beom-mu Kim, Seong-min Jeon, Seong-ro Lee Mokpo National Univ. Abstract Technology is a never ending process. To be able to design a product using the current technology that will be beneficial to the lives of others is a huge contribution to the community. This paper presents the design and implementation of Wireless Sensor tags which allows monitoring from anywhere with Internet access such as status of objects (open/close), movement and temperature of tagged items in your home or office. The tags can be set up to beep, once triggered through an Android or iOS app. Owners can receive alerts, push emails, read tweets through the app, once it monitors any changes in movement and temperature of tagged items.
Keywords – Wireless sensor tags, ethernet tag manager, cloud based web service.

Introduction
With the advent of low-power embedded systems and wireless networking, new possibilities emerged for distributed sensing applications. These technologies led to the implementation of Wireless Sensor networks (WSN), allowing easily configured, adaptable sensors to be placed almost anywhere, and their observations similarly transported over large distances via wireless networks[1]. Echevarria has presented a WebTag for a direct IP based access to a sensor tag over the Near Field Communication (NFC) technology for secure applications[1]. However, they faced the major challenge of providing a web access over radio frequency identification technology. This was because NFC and TCP/IP differ in their basic way of functioning. Other studies such as ones presented in [2] has examples of tracking objects using RFID and Wireless Sensor networks. In this study the authors have only given brief introduction of RFID, WSN and the integration of both. Yuksel has proposed a system design that combines the RFID systems with Wireless Sensor networks[3]. However, their system is not too feasible to be carried out as a low cost solution. The primary purpose of the current paper is to propose the new concept of Wireless Sensor tags which will enable owners to check current conditions and monitor any changes in movement of tagged items in home or office, even when they are not at home or in office. Moreover, once any movement is detected, the system uses autonomous emailing application to alert the owner.

Proposed System Architecture
This Wireless Sensor tag monitoring system consists of two main components: the Wireless Sensor tags and the Ethernet Tag

manager. Once these components have been configured, we will need to build an infrastructure to support them. Without a human interface, there is no way for the data collected by the sensors to be used. The purpose of this infrastructure is to provide a method for transporting event data from the sensor network to a human-readable form. To accomplish this, we therefore, propose the following design as illustrated in Fig. 1. Our system architecture offers an effective, a reliable, comprehensive, and low-cost solution to facilitate automatic monitoring and notification of objects from long distances. This diagram shows the interactions between each major component in the system. Beginning with the network of Wireless Sensors, information travels to the Cloud based Web service through the Ethernet Tag Manager. Users are able to view the status of the sensor network by using an application that queries event information from the data storage.
Ethernet Tag Manager However, in this paper, we present the STBC with multiple transmit antennas. The Ethernet Tag Manager is the brain of our system. It has long reading/writing ranges. It serves as a mobile mini application server between the Wireless Sensor tag system and a wireless network. It gathers data from tagged objects, process tag information and sends this information to related remote system that consists of computers, servers, or base stations. Tag manager will be connected to the internet using a cable (RJ45) and is powered using an AC adaptor. It runs an open-source operating system (TinyOS) [4] which is designed for low-power wireless devices.

The wireless network infrastructure can use different communication technologies, such as Bluetooth, ZigBee, Wi-Fi (IEEE 802.11 a/b/g/n), WiMAX (IEEE 802.16/x), and cellular networks (e.g., GSM, GPRS, EDGE, CDMA, etc.) to provide fast data communication, larger coverage area, and Internet access. This infrastructure can be a cloud that consists of various network topologies (or clouds) and many spatially distributed devices that produce convenient communication among themselves.
Overall System Operation Each Sensor tag will be unique and will have its own signature. A user can place it in a specific location or on a specific object for e.g. owner can put one on garage door and get a notification to their e-mail, twitter by the Android/iOS push service each time the door is opened or closed. This will be done based on the tag internal motion sensor which can also help keep track of other things being moved around while owner is not at home or in office, such as artwork or even the TV remote. The tag will also include a temperature measurement unit which can tell how hot or cold it is outside or inside.

Conclusion
In our study, we proposed a Wireless Sensor tag system that enables owners to track the movement or change in temperature of any item assigned to a tag, even when they are not at home or in office. The Wireless Sensor tag is a real-time, cloud based system, so any changes made from one device instantly appears on other devices. Additionally, this paper has discussed the ways to combine sensor tags with wireless communication technologies.
