In this work, we envisage an architecture of nanonetworks-based Coronary Heart Disease (CHD) monitoring, consisting of nano-macro interface (NM) and nanodevice-embedded Drug Eluting Stents (DESs), termed as nanoDESs. We study the problem of asymmetric data delivery in such nanonetworks-based systems and propose a simple distance-aware power allocation algorithm, named catch-the-pendulum, which optimizes the energy consumption of nanoDESs for communicating data from the underlying nanonetworks to radio frequency (RF) based macro-scale communication networks.

In this paper, we study the problem of asymmetric data delivery in various types of network topologies. We propose a distributed topology control algorithm based on the solution of the well-known network flow problem for addressing asymmetric data delivery. The generated topology is dynamic in the sense that it changes according to the energy levels of the nanoDESs. The proposed algorithm helps establish the topology and balance the load on nanoDESs. The proposed approach changes the topology if there arises a need to balance the energy content of the nanoDESs.

In this paper, we address the issue of catastrophic collision — a phenomenon which exhibits recurrent collisions of femtosecond long pulse symbols emanating from the nanodevices in a Wireless Bio-nanosensor Network (WB2N). The existing method of choosing the symbol rate does not completely avoid catastrophic collision. The severity of collision is further pronounced when molecular absorption noise gets compounded. In present work, we analyze the catastrophic collision and model the collision for WB2Ns to be successful e-health system.

In this work, we propose the phenomenon of collision in multi-conjugation of multiple carrier bacteria at the side of receiver nanodevice. We show the effect of this conjugation-based collision on the maximum achievable throughput of the network, using a simple graph-theoretic approach, namely, Maximum Weight Bipartite Matching. The proposed Max Throughput algorithm runs in polynomial time. The effect of various spatial distribution of nanodevices on the maximum achievable throughput are extensively analyzed and evaluated.

In this work, we envisage the architecture of Green Wireless Body Area Nanonetwork (GBAN) as a collection of nanodevices, in which each device is capable of communicating in both the molecular and wireless electromagnetic communication modes. The term green refers to the fact that the nanodevices in such a network can harvest energy from their surrounding environment. It is observed that the rate of energy harvesting is nonlinear and sporadic in nature. We specifically address the energy management problem in a ubiquitous healthcare monitoring scenario and formulate it as a cooperative Nash Bargaining game.

In this work, we analyze the energy consumption by engineered bacteria for releasing molecules and propagating for the tracking process. We show that the events of the release of molecules by engineered bacteria and their propagation are interlinked in such a way that the strategy of releasing attractants upon detecting the target is coupled to the energy available with the engineered bacteria. Based on the finding, we propose an energy-aware algorithm, named as EnPoS, which probabilistically selects a group of engineered bacteria among the deployed bacterial population to release signaling molecules over a particular time period in order for engineered bacteria to track the mobile targets. The simulation results show better performance of the proposed algorithm as compared with the basic algorithm incorporating continuous releasing of signaling molecules, concerning the energy expenses, mean displacement over time, and distribution of the engineered bacteria around the targets.

Dengue, a mosquito-borne viral disease, poses a global threat owing to the unavailability of any specific therapeutics. Since prevention is only restricted to vector control, a clear understanding of Dengue Virus (DENV) transmission within an infected host is essential. The dynamics of DENV transmission addressed in light of molecular communication paradigm is promising in providing crucial information accounting for disease control that can lead to development of novel approaches to clear the virus infection. An essential question is whether we can model the propagation behavior of DENV, and in particular its impact as it propagates through various sub-systems of the human body.

In this work, we focus on the transmission of COVID-19 particles via the respiratory tract. Our proposed work involves modeling the transmission and propagation of COVID-19 particles inside the respiratory tract once the virus particles get attached to the nasal passage. In particular, we focus on the virus amplification, propagation, and reception along the respiratory tract by taking into account the effect of diffusion and advection due to airflow. Moreover, we analyze the impact of the immune system in the growth as well as the propagation of COVID-19 particles through the channel. This work is completely theoretical. We didn't consider different strains of COVID-19. Read More PDF CITATION

In this work, we propose a novel system based on the emerging communication technology of wireless optogenetic networks of neural dusts to provide a longterm solution for the alleviation of resting tremor. Interfaced with neural dusts, each of the subthalamic nucleus neurons can be controlled and stimulated by the ultrasonic waves which are transmitted from a single/multiple subdural transducer(s) that are placed in the dura mater of the brain. Moreover, in order to address the challenging tasks of charging and addressing each of the neural dusts, we propose a protocol, named as Single Time Instant addressing Protocol, which outperforms the state-of-theart parallel charging protocol. The basic idea of our protocol is that it selects most frequently occurring spike patterns in a single time instant and assigns the pattern with an ultrasonic frequency.
