Object Tracking Using Ambient Backscatter Technology

Ambient backscatter is a new technology that uses ambient signals to enable communication. The system utilizes existing ambient RF radiations as the source of power and also utilizes the same as wireless medium for communication between devices. It leverages the ambient RF signals that are already around us, it does not require a dedicated power infrastructure as in RFID. The basic thought here is that there is a ton of energy in our environment specifically in the form of high-amplitude RF waves from broadcasts, and we should be able to use that energy to do work. With the help of this ambient backscatter technology, we keep in track of the objects/things which we wish to safe guard by keeping them as a transmitter. There is exchange of pulses (RF signals) that takes place between the transmitter and the receiver. When the receiver to which the object is connected is taken away (to some particular distance), the backscattering stops and hence we may use the micro-controller to intimate the user with the help of a message using GSM and track the location of the object using GPRS

A survey of symbiotic radio: Methodologies, applications, and future directions

The sixth generation (6G) wireless technology aims to achieve global connectivity with environmentally sustainable networks to improve the overall quality of life. The driving force behind these networks is the rapid evolution of the Internet of Things (IoT), which has led to a proliferation of wireless applications across various domains through the massive deployment of IoT devices. The major challenge is to support these devices with limited radio spectrum and energy-efficient communication. Symbiotic radio (SRad) technology is a promising solution that enables cooperative resource-sharing among radio systems through symbiotic relationships. By fostering mutualistic and competitive resource sharing, SRad technology enables the achievement of both common and individual objectives among the different systems. It is a cutting-edge approach that allows for the creation of new paradigms and efficient resource sharing and management. In this article, we present a detailed survey of SRad with the goal of offering valuable insights for future research and applications. To achieve this, we delve into the fundamental concepts of SRad technology, including radio symbiosis and its symbiotic relationships for coexistence and resource sharing among radio systems. We then review the state-of-the-art methodologies in-depth and introduce potential applications. Finally, we identify and discuss the open challenges and future research directions in this field
