In addition, antenna provides the gain of 6.45 dBic along with 98% radiation efficiency. The proposed antenna can also be used for the implementation of multi-port wireless THz communication systems with the advantage of tunable CP response with impeccably high radiation performance parameters. A two-port multi input, multi output (MIMO) antenna is implemented with the usage of the proposed metal strip coated DR.

The communication of the nanobots in the sense of intrabody nanonetworks allows possibilities of innovative medical applications for monitoring, drug delivery, and nanosurgery inside the human body. Due to their incredibly small sizes, the nanobots have to operate under extreme computational and energy constraints.

Thus, energy management<span> is very important for the feasibility of the intrabody nanonetworks by directly impacting their performance and reliability. In this paper, we propose a hybrid wired/wireless intrabody ultra-dense nanonetwork architecture where the nearby nanobots form temporarily wired clusters reducing the required total wireless transmission and reception in the network leading to the lower energy use of the communication. We consider the use of coaxial nanocables terminated by nanomagnets to form nano-wired clusters with self-aligned and binding magnetic nanoplugs. Due to the highly dynamic topology<span> of these nano-wired clusters, we propose a very lightweight and adaptable clustering and energy management algorithm to select cluster heads on-the-fly and transmit data wiredly in the cluster and wirelessly between the clusters.

The aim is to present a unified framework using communication engineering, and to highlight future research directions for modeling the spread of infectious diseases through airborne transmission. We introduce the concept of mobile human ad hoc networks (MoHANETs), which exploits the similarity of airborne transmission-driven human groups with mobile ad hoc networks and uses molecular communication as the enabling paradigm. In the MoHANET architecture, a layered structure is employed where the infectious human emitting pathogen-laden droplets and the exposed human to these droplets are considered as the transmitter and receiver, respectively. Our proof-of-concept results, which we validated using empirical COVID-19 data, clearly demonstrate the ability of our MoHANET architecture to predict the dynamics of infectious diseases by considering the propagation of pathogen-laden droplets, their reception and mobility of humans.</p></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"32 ","pages":"Article 100410"},"PeriodicalIF":2.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9385271/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10744788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One major challenge for this type of communication paradigm is to determine the identity of the transmitting nodes and the events. From previous works, we know that different amount of energy is discharged in the environment from different events. This motivates us to propose an energy-neutral event recognition framework using pulse position modulation in which the event information is transmitted by the sensors that use the energy harvested from the event. In this framework, we use pulse position to identify transmitting nodes communicating with a single receiver. However, using this approach, we can also encode the identity of multiple receivers when a single node communicates with them without employing an addressing scheme in IoNT networks. In both cases, the energy observation of the received pulse helps in identifying the event type. The feasibility of the proposed framework is demonstrated by a large number of numerical simulations which include terahertz channels. We find that the proposed framework achieves 99% accuracy for detecting ten different event types at a distance of 30 mm.</span></span></p></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"31 ","pages":"Article 100393"},"PeriodicalIF":2.9,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72101429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
