Abstract

The objective of this chapter is to provide an innovative system for tracking and monitoring objects using RF transmitters and receivers, and querying about these objects using mobile phones. The protocol for the system and a simulation to check the feasibility of this project before applying it to a real world scenario is presented below. In this simulation, capability of the transmitter and receiver is tested to communicate effectively and also display the data sent by the transmitter. As a result, a highly flexible wireless controlled system would enable bridging the distance between the user and the electronic device, and hence, provide easier access to real world entities, by just manoeuvring the mobile phones, without the need to be physically present near the object. Also, it is being enhanced to ensure an authenticated access to these resources, thereby taking care of the security aspect. The working of the system can be divided into two phases: phase one comprises a pair of RF transmitter and receiver coupled with a central database, and phase two is comprised of GSM modem with a unique SIM linked to the central data base via GSM network. In the first phase of the system, RF transmitters are tagged to the objects of everyday use and have the capability of transmitting signals, and the paired receiver detects the transmission of the tagged object and stores its corresponding location in the central database, which is created specifically for information maintenance of the tagged objects. In the second phase of the system, a mobile phone is used to query the location of any tagged objects based on its availability in the vicinity, by sending a message to the SIM connected to a GSM modem. If an object is present, the GSM modem fetches the location and other relevant information from the central database and encapsulates this information into a message, which is sent back to the mobile device or phone that has requested the information.

Introduction

The growth in technology facilitates competitive and less expensive devices; keeping this in mind a flexible system is put forth to play a major role in future computing systems. The aim of the system is to ensure a degree of freedom for an individual to locate objects in his vicinity without the need of any physical movement. This is done by monitoring everyday physical processes or entities and keeping track of it by a central database, provides novel features to the system. What currently hinders most of the conceived parallel similar type of systems from becoming commercial applications, however, is a lack of adequate infrastructure of following types: First, a well marked sensing infrastructure must be installed in area or block wise to perform an efficient and ordered sensing task. Second, a communication infrastructure is required to transmit the data within the network of the connected devices; this involves distribution and aggregation of readings from multiple transmitters and so on. Thirdly, a commercial infrastructure is needed to manufacture and deploy the transmitting, receiving and communicating devices like GPS system, and to generate revenue from the system.

Compared to these hindrances, authors propose a system with a unique approach to establish a relationship between RF transmitters and receivers using a microchip, and link it to the GSM network, to provide an uninterrupted access to the data by the user. The incorporation of mobile phones in the system provides a unique opportunity to overcome most of the difficulties, indicating the ease of operating the system by an individual without the need of a specialized knowledge. Sensing technologies can be implemented using transmitters and a receiver and, data from the central database can be accessed from the mobile handset via wireless mobile networks. Wide area communication is a core property of the cellular network. It enables the integration of data from many transmitters and the support of applications with backend services such as data storage in a central system. The effectiveness of the system is shown by locating important day to day entities or objects, whether moveable or fixed, and querying their information by various users irrespective of their location.

Making use of these unique properties of mobile phones, RF components and the cellular network, proposed system is mainly concerned with monitoring and locating objects by means of mobile phones, and sensing functionality carried out by the objects that are tagged with the hardware i.e. the transmitters in the vicinity, and are detected by the corresponding receivers. And the location is queried from the central database using a mobile phone by means of a GSM modem. The dual technique employed in this project is: First, object sensing using the RF transmitters and receivers. Second, user interface provided by the mobile phone aid for sensing and querying the personal items simultaneously. This system allows to identify a particular challenge that is common to many applications that makes use of large people-centric infrastructure provided by mobile phones and the cellular network. The challenge is to answer the question of whether a system based on RF transmitters and receiver can provide sufficient coverage in relatively short period of time. In an extensive evaluation, which includes a real-world experiment with the object localization prototype, analysis of properties of the coverage obtained given a wide range of different operational parameters such as the distance between transmitter and receivers, objects in the path of transmission and range of the transmitters used were performed. The study deals with the feasibility of object localization based on mobile phones and can provide valuable guidelines for the design of future people-centric sensing systems in general (Christian, Philipp, Christof, & Wolfgang , 2008).

Security aspect is an essential factor that surrounds any network based application. Strengthening the security aspect of the system strengthens its application, thereby indicating a linear relation among the two. It is important to realize and ensure a reliable secured network based application, without which the entire system and its application tend to be meaningless. Therefore security presents sacrosanct part of the system, hence needs to be addressed with due diligence. Keeping this in view, few security related operations of this system that will increase the overall credibility and reliability of the task being carried out such as Iris scan, Finger print secured access and Encrypted password access are discussed.
