The hospitality industry acquires the features of an integrative industry, which combines material resources and intangible factors to meet the needs of modern man for comfortable travel and recreation. Hospitality is interpreted as a complex economic, social, cultural, psychological phenomenon, the impact of which on the development of the tourism industry determines the effect of synergy from the combination of tourist resources and quality of service. The author of article proposes to consider hospitality management as a multilevel dynamic management system for the process of providing services to tourists and vacationers, based primarily on the principles of humanism, tolerance, personalization of hospitality, respect for cultural diversity, priority to meet human needs for quality recreation and physical strength as well as cultural self-development. The social orientation of this system to some extent balances the commercial, purely pragmatic aspect of managing the development of tourism enterprises. A holistic model of hospitality management is based on a harmonious combination of four concepts. They are humanitarian, technological, functional and commercial. The system-forming component of the hospitality sector is a mechanism for managing consumer behaviour, which ensures an optimal balance of supply and demand in the market of hospitality services. The specifics of service in the hospitality industry is that the quality of service affects the emotional perception of tourists in the area and, accordingly, affects the image of the state. Therefore, the mechanism for implementing the service policy should be established through public administration measures. Among the key areas of hospitality management development is the formation of a rational organizational structure, improvement of hospitality marketing and support of corporate culture, the values of which are adequate to the socio-cultural environment of the hospitality industry. The specificity of the hospitality industry is also that an important role in ensuring competitiveness is played by an attractive brand, which stipulates the allocation in the management system of such a component as brand management. Considerable attention should be paid to the innovative development of hospitality enterprises and the constant improvement of professional competence of managers of socio-cultural activities.


With traffic increase in a wireless network beyond its capacity and as the number of connected devices continue to grow, the quality of service (QoS) degrades. In this paper we study the impact of mobility on throughput in the case of an infrastructure wireless network using IEEE 802.11 Wi-Fi standard. Since we found in the literature that the mobility of stations can have an impact on the quality of service, we try to remedy to this by implementing a new access category reserved for mobile stations. First we compare the throughput between static and mobile nodes, both connected to a QoS station. Then we propose our new model that consists of adding a new access category used by mobile nodes regardless of their traffic category. The study was made by simulating different scenarios using Network Simulator-3 (NS-3). We found that the throughput may vary depending on the simulation scenario. The simulation results show that with the proposed solution the mobile nodes can have a better throughput.
