“…In the literature, recent works covering heterogeneous systems usually consider either a macro LTE BS associated with several micro LTE BSs, as in [4], or Wi-Fi APs associated with a macro LTE BS, as in [7], [8]. The present work goes further and considers a novel scenario in which LTE BSs interwork with NR BSs.…”

“…Besides the challenge of keeping the mobility performance achieved by small cell deployments comparable with that of a macro only network, highlighted in [7], other challenge related to heterogeneous systems is the signaling overhead in the CN due to frequent handovers. This problem is addressed in [8], where a mechanism exploiting the interworking between LTE and Wi-Fi is proposed as a solution for mission-critical communications.…”

“…In actual work, certainty and uncertainty often appear. Uncertainty phenomenon has random uncertainty and fuzzy uncertainty and the latter is difficult to solve with precise mathematics; so effective exploration must be carried out with the help of method theory in fuzzy mathematics to solve the problem of fuzzy uncertainty [9]. Fuzzy and uncertain phenomena can be seen everywhere in industrial production, corporate management and other production, and social practices.…”

The establishment of communities is for the better operation and management of cities, and community safety has gradually become a topic of increasing concern. It is not only an important part of the community public safety system, but also the foundation of social and economic development. With the improvement of the overall economic level of society, wireless network coverage has been greatly improved, smart devices have also been rapidly developed and popularized, and location-based information service systems have gradually entered the field of community public safety. At present, my country still lacks experience in community safety management. At the same time, there is no complete set of standards and evaluation system for the public safety evaluation system of urban communities. However, community public safety involves people’s livelihood issues and the stability and development of the city. Therefore, it is urgent to build a community public safety evaluation system based on the location information service architecture. Based on the safety community research and location service system, this paper uses the combination of theory and practice, quantitative and qualitative methods, and tentatively explored and constructed a community public safety evaluation system based on the location information service architecture. This article integrates location information service technology into the community public safety evaluation system, selects three indicator factors, investigates a more comprehensive evaluation subject, and combines the evaluation subject’s qualitative evaluation of community public safety with quantitative evaluation through fuzzy comprehensive evaluation. This paper conducts an empirical analysis of a certain community and finds that its public safety evaluation score is 62.6232 points, which is in the “general” ranks, and it needs to be combined with the location information service system to improve the community safety issues. This study has guiding significance for ensuring community public safety and has theoretical and practical significance for community construction and development.

“…Wi-Fi Direct is a strong candidate to offload cellular traffic [8]. The ability of quickly creating groups and disseminating information of Wi-Fi Direct can be used in mission-critical communications for public safety [9]. Proactive routing protocols can be used with Wi-Fi Direct to build Mobile Ad-hoc Networks (MANET) [10].…”

SDN-based Wi-Fi Direct clustering for cloud access in campus networks

Mobile cloud is changing the way to enroll teaching activities in university campus. Lectures and lab sessions can be carried out directly from tablets in a class room by accessing a server in the cloud. In this paper, we address the problem of high density cloud access with wireless devices in campus networks. We propose to use Wi-Fi Direct clustering to solve the problem of Quality of Service (QoS) degradation when a high number of wireless devices want to access a content in the cloud at the same time. A centralized softwaredefined network controller is used in our proposed architecture to capture the network state and organize the Wi-Fi Direct groups. The optimized number of clusters can be calculated in function of the number of devices in the room. By simulations, we show that we can provide a better QoS in terms of download time and application's throughput by reducing the interference in this dense wireless network environment.
