Network security has always been an area of priority and extensive research. Recent years have seen a considerable growth in experimentation with biologically inspired techniques. This is a consequence of our increased understanding of living systems and the application of that understanding to machines and software. The mounting complexity of telecommunications networks and the need for increasing levels of security have been the driving factor. The human body can act as a great role model for its unique abilities in protecting itself from external

Because of the deployment of sensors would be typically in random fashion. It would not be feasible to recharge the batteries of a moribund sensor. Hence, how to prolong the lifetime becomes a principal issue in wireless sensor networks. In this thesis, we emphasize on a problem of routing and scheduling the activities of all sensors in a data-centric wireless sensor network. We propose a mathematical formulation to model this pr

Abstract:

Understanding human behaviour is key to understanding the spread of epidemics, habit dispersion, and the efficacy of health interventions. Investigation into the patterns of and drivers for human behaviour has often been facilitated by paper tools such as surveys, journals, and diaries. These tools have drawbacks in that they can be forgotten, go unfilled, and depend on often unreliable human memories. Researcher-driven data collection mechanisms, such as interviews and direct observation, alleviate some of these problems while introducing others, such as bias and observer effects. In response

Abstract:

The astronomical increase in the number of wireless devices such as smart phones in 21th century has revolutionized the way people communicate with one another and share information. The new wireless technologies have also enabled researchers to collect real data about how people move and meet one another in different social settings. Understanding human mobility has many applications in different areas such as traffic planning in cities and public health studies of epidemic diseases. In this thesis, we study the fundamental properties of human contact graphs in order to characterize how peopl

Abstract:

<div>Decades of scaling in semiconductor technology has resulted in a drastic reduction in the cost and size of unit computing. This has enabled computing capabilities in small form factor wearable and implantable devices. These devices communicate with each other to form a network around the body, commonly known as the Wireless Body Area Network (WBAN). Radio wave transmission over air is the commonly used method of communication among these devices. However, the human body can be used as the communication medium by utilizing its electrical conductivity property. This has given rise to Human

Abstract:

The current trend in healthcare is the move towards proactive health monitoring and making health one’s responsibility. This has seen a proliferation of wearable devices that monitor physical and physiological parameters in real time. However, there is an increasing need to monitor internal body parameters, detect risks and act on them in a timely manner. Implanted medical devices (IMDs) are gaining recent attention due to their capability to provide diagnostic, therapeutic and assistive functionalities. With a projected annual growth of 7.1 % (2016- 2022) the global market share of IMD

In such transmissions, only a small fraction of this energy is received since the EM fields are widely radiated resulting in lossy inefficient systems. Using the body as a communication medium (similar to a ’wire’) allows for the containment of the energy within the body, yielding order(s) of magnitude lower energy than radiative EM communication.
