Abstract—Smart homes and Wireless Home Automation Networks (WHAN) face several challenges in terms of cost, scalability, reliability, delay, energy consumption and many others. Smart homes typically have huge number of communicating devices. Efficient management of network resources is a major challenge in such environments. This paper provides insights on how to improve the MAC layer in smart home networks to fulfil the requirements of the different smart home applications. It provides a classification of the different smart home applications and identifies (...) the main requirements and challenges regarding the MAC layer in this environment. It also provides insights for MAC protocols designers by highlighting the main issues in designing MAC schemes for smart home environment. Based on the analysis, the paper highlights adaptability as the most critical and challenging feature for smart home MAC protocols. (shrink)

This proceedings book is the offspring of the online national conference on “Reading and Writing with ICTs: Teachers’ and Learners’ Perceptions” that was held on 9/10 March 2022 at Badji Mokhtar University- Annaba- Algeria.

In English: The aim of the article is to analyze the basic assumptions of Roman Ingarden’s ethics. His views are discussed from the perspective of questions about the source of moral oughtness. Therefore, the main analysis is focused on the relationship between moral values and the oughtness needed to realize them. Ingarden’s position is placed in a broader ethical context; the important question is whether it is in the idea of the particular value or in the experience of the particular (...) value in the past. The answer to this question reveals the nature of Ingarden’s ethical thought, in which there is no room for blind obedience to norms or principles. That is why, in order to properly understand Roman Ingarden’s ethics, it is so important to define what constitutes the source of moral duty and the oughtness to act. -/- Po polsku: Celem artykułu jest analiza podstawowych założeń etyki Romana Ingardena. Jego poglądy omawiane są z perspektywy pytań o źródło moralnej powinności. Dlatego też główne analizy skupiają się na relacji między wartościami moralnymi a powinnością potrzebną do ich realizacji. Stanowisko Ingardena zostaje umieszczone w szerszym kontekście etycznym. Istotne jest pytanie, czy tkwi ono w idei danej wartości, czy w doświadczeniu danej wartości w przeszłości. Odpowiedź na to pytanie ujawnia specyfikę myśli etycznej Ingardena, w której nie ma miejsca na ślepe posłuszeństwo wobec norm czy zasad. Dlatego dla dobrego zrozumienia etyki Romana Ingardena tak ważna jest odpowiedź na pytanie, co stanowi źródło powinności moralnej i powinności działania. (shrink)
