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.
