The fifth-generation mobile communication technology (5G) provides high-bandwidth and low-latency data channels for massive IoT terminals to access the core business network. At the same time, it also brings higher security threats and challenges. Terminal identity authentication is an important security mechanism to ensure the core business network; however, most of the existing solutions adopt a centralized authentication model. Once the number of authentication requests exceeds the processing capacity of the authentication center service, it will cause authentication request congestion or deadlock. The decentralized authentication model can effectively solve the above problems. This article proposes a decentralized IoT authentication scheme called A2 Chain. First, A2 Chain uses edge computing to decentralize the processing of authentication requests and eliminate the burden on authentication services and the network. Second, to implement cross-domain identity verification of IoT devices, A2 Chain uses blockchain, and sidechain technologies are used to securely share the identity verification information of IoT devices. Additionally, A2 Chain replaces public key infrastructure (PKI) algorithm with identity-based cryptography (IBC) algorithm to eliminate the management overhead caused by centralized authentication model.

In the value chain it is important to keep in mind the core business of the company, since it depends largely on the competitiveness of the company and its overall performance, bearing in mind that all business indicators depend on it. In this work we will study the washing process within the company WASH CONTAINERS SA DE CV, to improve the washing processes and in this way reduce times and movements in the process leading the company to reduce costs considerably within the operations company daily, having a more competitive operation and with greater profit margin in its business process. Goals: It Improve the logistics of the movement of containers for washing and with it the core business of the company. Methodology: The action research will be applied applying Business Process Management for the improvement of processes in situ, it will be developed in a certain period of time and with that it will establish an improvement projection. Contribution: The improvement of the times for the disposal of the containers and their subsequent use, allows a better competitiveness and with it the income of the company, on the other hand, the transport companies improve in performance in quantity, quality of disposition and with it their income.

Purpose The purpose of this paper is to identify the main activities that startups outsource and the elements involved in outsourcing decisions. Design/methodology/approach A multi-case study composed of Brazilian startups was conducted. Data through interviews and secondary sources were obtained. Two groups of startups were considered and analyzed comparatively: startups in the development stage and in the sales stage. Findings The findings show that even though the literature suggests that the core business should not be outsourced, some startups do have to outsource this kind of activity. That was the main difference found between startups in the sales stage and in the development stage: the former group has a solid structure, knowledge and resources, so they can keep the core business inside the firm; whereas the latter group has little experience, scarce knowledge and resources, making outsourcing a more attractive alternative. Originality/value Theoretically, this paper approaches a perspective underexplored in the innovation and management literature: outsourcing in startups. It highlights how outsourcing, as a decision between making and buying, can help startups to improve success potential. In practice, this paper discusses and demonstrates why and what can be outsourced by startups in the development and in the sales stages to overcome their limitations and, consequently, achieve better innovative results.

The article is devoted to assessing the effect of the implementation of information technologies in non-profit organizations. The purpose of the assessment is to evaluate the effect of IT implementation and its impact on key performance indicators of an organization. The indicators characterizing the results of the organization’s activities in accordance with the State Assignment and the results of commercial activities were used as the key performance indicators. For federal state budget NPOs, it has been shown that a positive IT effect for auxiliary business processes does not directly ensure positive performance indicators for the core business processes. Hidden effects of the use of IT were assessed by changes of the indicators of the core business processes. Performance indicators characterizing the results of commercial activities may demonstrate a negative effect. Understanding the specifics of non-profit organizations, as well as metrics and performance parameters characterizing the effectiveness of such organizations, is important to ensure a correct approach to the digitalization of business processes and their performance management.

In wireless communication, Fifth Generation (5G) Technology is a recent generation of mobile networks. In this paper, evaluations in the field of mobile communication technology are presented. In each evolution, multiple challenges were faced that were captured with the help of next-generation mobile networks. Among all the previously existing mobile networks, 5G provides a high-speed internet facility, anytime, anywhere, for everyone. 5G is slightly different due to its novel features such as interconnecting people, controlling devices, objects, and machines. 5G mobile system will bring diverse levels of performance and capability, which will serve as new user experiences and connect new enterprises. Therefore, it is essential to know where the enterprise can utilize the benefits of 5G. In this research article, it was observed that extensive research and analysis unfolds different aspects, namely, millimeter wave (mmWave), massive multiple-input and multiple-output (Massive-MIMO), small cell, mobile edge computing (MEC), beamforming, different antenna technology, etc. This article’s main aim is to highlight some of the most recent enhancements made towards the 5G mobile system and discuss its future research objectives.

5G or fifth generation of cellular technology, is the successor of 4G LTE. It focusses on high date rate, high system capacity cheaper cost. Although it is still a maturing technology, the countries around the world have already stared implementing of on experimented basis. Massive connectivity is at the core of 5G and thus aim to get different components around us connected to each other. The paper focusses on minkowski loops fractal structures till 2nd iteration making a simpler and cheaper antenna for 5G application of cellular technology. The main feature of this antenna is that it occupied the same space as a regular pattern antenna, but offers a far bigger length for radiation. The resonant frequency taken is 30GHz. The substrate taken is RT-Duriod 6006 with dielectric constant 6.45. The antenna has been designed, simulated and analyzed using the software high frequency structure simulator.
