Social Internet of thing (SIoT) is an emerging area that introduces sociology theories into IoT networks, in order to support the spread behaviour of multimedia contents. With the explosive growth of data in the internet, traditional solutions are no longer suitable for large-scale SIoT networks. To address this challenge, this work target to optimize the information propagation in SIoT networks. First, we establish a novel model to divide SIoT network into communities on the basis of network social attributes. Second, we propose an information dissemination control mechanism based on variation trends of content popularity, in order to maximize the spread performance of information. Third, we check the relations between performance indicators and network attributes via a computer simulation. Simulation results show the feasibility of the proposed mechanism. Simulations results also reveal that the proposed mechanism make better balance compared with existing solutions in terms of efficiency and complexity.

“…The relay node resides in the environment can be an artificial nanomachine [14] or biological one [20]. In nature, many biological systems have the both of molecule emission and reception capabilities [23], [24], for example, biochemical positive feedback loops process is common in protein channel of human body [25]. These are a key for designing a nanomachine, which acts as relay node.…”

“…For example, in case of utilizing DMC in drug delivery, the time of releasing the drugs into the intended location is controlled by the drug releasing mechanism [4]. Our target is finding the symbol duration ratio (t s,DMC ) in a way that (24) holds. Next, we formulate an optimization algorithm for finding the optimum time slot partitioning to achieve the best performance in E2E communication.…”

Telemedicine refers to the use of information and communication technology to assist with medical information and services. In health care applications, high reliable communication links between the health care provider and the desired destination in the human body play a central role in designing end-toend (E2E) telemedicine system. In the advanced health care applications, e.g. drug delivery, molecular communication becomes a major building block in bio-nano-medical applications. In this paper, an E2E communication link consisting of the electromagnetic and the molecular link is investigated. This paradigm is crucial when the body is a part of the communication system. Based on the quality of service (QoS) metrics, we present a closed-form expression for the E2E BER of the combination of molecular and wireless electromagnetic communications. Next, we formulate an optimization problem with the aim of minimizing the E2E BER of the system to achieve the optimal symbol duration for EC and DMC regarding the imposing delivery time from telemedicine services. The proposed problem is solved by an iterative algorithm based on the bisection method. Also, we study the impact of the system

With the emergence of the COVID-19 pandemic, the World Health Organization (WHO) has urged scientists and industrialists to explore modern information and communication technology (ICT) as a means to reduce or even eliminate it. The World Health Organization recently reported that the virus may infect the organism through any organ in the living body, such as the respiratory, the immunity, the nervous, the digestive, or the cardiovascular system. Targeting the abovementioned goal, we envision an implanted nanosystem embedded in the intra living-body network. The main function of the nanosystem is either to perform diagnosis and mitigation of infectious diseases or to implement a targeted drug delivery system (i.e., delivery of the therapeutic drug to the diseased tissue or targeted cell). The communication among the nanomachines is accomplished via communication-based molecular diffusion. The control/interconnection of the nanosystem is accomplished through the utilization of Internet of bio-nano things (IoBNT). The proposed nanosystem is designed to employ a coded relay nanomachine disciplined by the decode and forward (DF) principle to ensure reliable drug delivery to the targeted cell. Notably, both the sensitivity of the drug dose and the phenomenon of drug molecules loss before delivery to the target cell site in long-distance due to the molecules diffusion process are taken into account. In this paper, a coded relay NM with conventional coding techniques such as RS and Turbo codes is selected to achieve minimum bit error rate (BER) performance and high signal-to-noise ratio (SNR), while the detection process is based on maximum likelihood (ML) probability and minimum error probability (MEP). The performance analysis of the proposed scheme is evaluated in terms of channel capacity and bit error rate by varying system parameters such as relay position, number of released molecules, relay and receiver size. Analysis results are validated through simulation and demonstrate that the proposed scheme can significantly improve delivery performance of the desirable drugs in the molecular communication system.
