TL;DR: In this article, a handshaking algorithm for setting up communications once two radios have arrived in the same frequency channel was proposed. But the authors did not investigate the effect of different jamming techniques on blind rendezvous algorithms that utilize this handshake.
Abstract: : Blind frequency rendezvous is an important process for bootstrapping communications between radios without the use of pre-existing infrastructure or common control channel in a Dynamic Spectrum Access (DSA) environment. In this process, radios attempt to arrive in the same frequency channel and recognize each other's presence in changing, under-utilized spectrum. This paper refines existing blind rendezvous techniques by introducing a handshaking algorithm for setting up communications once two radios have arrived in the same frequency channel. It then investigates the effect of different jamming techniques on blind rendezvous algorithms that utilize this handshake. The handshake performance is measured by determining the probability of a handshake, the time to handshake, and the increase in time to rendezvous (TTR) with a handshake compared to that without. The handshake caused varying increases in TTR depending on the time spent in each channel. Four different jamming techniques are applied to the blind rendezvous process: noise, deceptive, sense, and Primary User Emulation (PUE). Each jammer type is analyzed to determine how they increase the TTR, how often they successfully jam over a period of time, and how long it takes to jam. The sense jammer was most effective, followed by PUE, deceptive, and noise, respectively.

TL;DR: Enhanced Handshake based two or three access conventions is proposed, which aims to address the problem of energy consumption in an environment where broadcasting a packet does reach all neighbours but only the neighbours who are all awake at the time can receive the packets quickly.
Abstract: In this environment, transmitting data to the end user becomes energy consuming, because broadcasting a packet does reach all neighbours but only the neighbours who are all awake at the time can receive the packets quickly. A hub can ahead its bundle to all partners by continually transmitting the parcel for an entire wake-up span, anyway it prompts high vitality admission and high scattering delay. Here, Enhanced Handshake based two or three access conventions is proposed. Every hub advances the parcel, as long as there might be a neighbouring hub that has now not got the bundle yet. As additional hubs procure the parcel, transmit length of the sender will turn out to be longer, subsequently ingesting more quality. Since the request for scattering is diverse each time, power admission is obviously adjusted a portion of the hubs, without unequivocal measures.
TL;DR: In this article , a handshake round was used to reduce intravenous intravenous (IV) antibiotic use in patients with hematologic malignancies in a quaternary care setting.
Abstract: Abstract Objective: To design and implement “handshake rounds” as an antibiotic stewardship intervention to reduce inpatient intravenous (IV) antibiotic use in patients with hematologic malignancies. Design: Quasi-experimental analysis of antibiotic use (AU) and secondary outcomes before and and after handshake rounds were implemented. Setting: Quaternary-care, academic medical center. Patients: Hospitalized adults with hematologic malignancies receiving IV antibiotics. Methods: We performed a retrospective review of a preintervention cohort prior to the intervention. A multidisciplinary team developed criteria for de-escalation of antibiotics, logistics of handshake rounds, and outcome metrics. Eligible patients were discussed during scheduled handshake rounds between a hematology–oncology pharmacist and transplant–infectious diseases (TID) physician. Prospective data were collected over 30 days in the postintervention cohort. Due to small sample size, 2:1 matching was used to compare pre- to and postintervention AU. Total AU in days of therapy per 1,000 patient days (DOT/1,000 PD) was reported. Mean AU per patient was analyzed using Wilcoxon rank-sum test. A descriptive analysis of secondary outcomes of pre- and postintervention cohorts was performed. Results: Total AU was substantially lower after the intervention, with 517 DOT/1,000 PD compared to 865 DOT/1,000 PD before the intervention. There was no statistically significant difference in the mean AU per patient between the 2 cohorts. There was a lower rate of 30-day mortality in the postintervention cohort and rates of ICU admissions were similar. Conclusions: Conducting handshake rounds is a safe and effective way to implement an antibiotic stewardship intervention among high-risk patient population such as those with hematologic malignancies.

TL;DR: In this article , the authors proposed a method to improve communication throughput by selecting multiple secondary senders from the primary sender's neighbors that never interfere with the other primary transmissions and make new transmission immediately after the extended RTS/CTS handshake for protecting the new full-duplex transmissions.
Abstract: AbstractRecently, with the rapid development of the Internet of Things (IoT) technology, wide variety of objects in our surrounding environment newly connected to a network. In order to provide continuous network services, the limited communication resources must be utilized effectively.In order to increase network capacity, full-duplex wireless communication allowing a node to simultaneously transmit while receiving on the same communication channel has became more attractive. Compared to the half-duplex wireless communication where a node can either transmit or receive at once, full-duplex wireless communication can achieve as up to twice as the communication capacity. However, in order to maximize the use of full-duplex wireless communication, appropriate scheduling on simultaneous transmissions and selecting the appropriate destinations avoiding collisions with the other transmissions, are required.In this paper, we propose a method to improve communication throughput by selecting multiple secondary senders from primary sender’s neighbors that never interfere with the other primary transmissions. In addition, our proposal make new transmission immediately after the extended RTS/CTS handshake for protecting the new full-duplex transmissions.

TL;DR: In this article , the authors provide an introduction to Industry 4.0 with the help of the cyber manufacturing system in association with IoT and blockchain, which is a rising period of network and collaboration among parts, machines, and people that can possibly make huge creation and proficiency profits, upgrades in personal satisfaction and maintainable natural results.
Abstract: Manufacturing is an important contributor to productivity, innovation, and trade. Technological revolution occurred with the change in time. After passing some revolution, today’s industry handshake is with Industry 4.0. Industry 4.0 is a rising period of network and collaboration among parts, machines, and people that can possibly make huge creation and proficiency profits, upgrades in the personal satisfaction and maintainable natural results. India is now rolling with digitalization and it has been seen its important and attractive growth market. Innovation is one of numerous components making makers reevaluate the manner in which they work. Computerization, apply autonomy, and the usage of cutting edge fabricating strategies have drastically changed the industrial facility floor and the assembling forms that happen there. This study provides an introduction to Industry 4.0 with the help of the cyber manufacturing system in association with IoT and blockchain.
