This book provides and assesses the techniques required for the realization of practical wireless-powered backscatter systems for large-scale and intelligent IoT networks. It explores the deployment, reliability, and security aspects of backscatter devices for both indoor and outdoor environments. The book also sheds light on some of the recently evolving technologies such as artificial intelligence/ machine learning, non-orthogonal multiple access (NOMA), and multi-tone carrier techniques and identifies their application in backscatter communications. In addition, it offers a valuable blueprint for future studies in the domains of intelligent reflective surfaces, ambient backscatter communications and massive IoT networks.

Research Paper (postgraduate) from the year 2016 in the subject Computer Science - Internet, New Technologies, , language: English, abstract: Due to the success of rapidly evolving wireless sensor networks (WSN), innovating localization techniques have been proposed by researchers all over the world. Since wireless sensor nodes are small devices with limited processing power and the channel conditions are difficult to predict, therefore, there is a desperate need of a low complexity algorithm that can efficiently identify channel condition and select an appropriate method of localization. Related to this, I present in this article a novel localization scheme that is very efficient in detecting the location in real world environment which is usually a mixed case of line of sight and non-line of sight. Simulation results show that this scheme reduces the delays in localization and increases the lifetime of nodes while maintain a fairly low mean estimation error. The results also demonstrate that this scheme performs fairly well even when there are limited numbers of anchor nodes.

Research Paper (postgraduate) from the year 2016 in the subject Computer Science - Internet, New Technologies, , language: English, abstract: The ability to achieve security at physical layer has remained a formidable task for the research community. The difficulty increases in case of multiple cooperating (i.e. exchanging and combining information) eavesdroppers. Therefore, in this article, we characterize the secrecy rate that can be achieved in the presence of cooperating eavesdroppers between a sink and multiple sensor nodes i.e. SISOME scenario. We quantify how the cooperating eavesdroppers using MRC (Maximal-Ratio Combining) and SD (Selection Diversity) techniques make it challenging to secure information. We then propose a scheduling scheme where a sensor with highest secrecy capacity is scheduled to transmit data. The analysis of intercept probability and secrecy outage probability clearly shows that using the scheduling scheme helps to provide greater security without any additional hardware complexity or power cost.

Research Paper (postgraduate) from the year 2016 in the subject Communications - Multimedia, Internet, New Technologies, , language: English, abstract: Industrial wireless sensor nodes (I-WSNs) have grabbed the attention of researchers all over the world in recent years. One of the major challenges faced by the researchers is the rapid fluctuation of signal due to machinery hindrance, thermal noise and vibration of metal. In an information-theoretic sense, this fluctuation degrades the secrecy capacity of the system in the presence of an eavesdropper. In this context this paper analyses the outage behavior of an industrial WSN which consists of a multiple sensor nodes and a sink, where data is transmitted over a wireless link. It also proposes the use of sensor scheduling to improve the physical layer security against a malicious eavesdropper, where a sensor with higher secrecy capacity is scheduled to transmit its data to sink. For both the conventional round-robin scheduling and the proposed optimal scheduling schemes, closed-form expressions for the intercept probability are derived.
