A Stochastic Approach for Analysis of Shadowing Effects in Urban Area

5G networks are started to be deployed in urban areas in the dynamic spectrum sharing mode. Therefore, the analysis of Non-Line-of-Sight (NLOS) shadowing effects behind buildings of different heights becomes particularly important. The shadowing of GSM (900 MHz), UMTS (2100 MHz) and LTE (1800 MHz) technologies was investigated in the urban area. The results are examined by using the log-normal path loss model and four different stochastic equations, specifically: normal, log-normal, Rayleigh, and Nakagami. The results showed that the fluctuations of path losses in the urban area correspond to the model of log-normal path losses. However, path losses for individual buildings do not fit this model. Therefore, stochastic methods were used to analyse shadowing effects. A path loss model based on a differential stochastic equation was proposed. This model includes the following values: free space losses, path losses disturbance due to the shadowing effect, standard deviation σ, and a freely chosen parameter b. This model allows a very accurate estimate of the path losses of the three technologies. A clear correlation was observed between parameter b and standard deviation σ.

EFFICIENT MODEL FOR AUTOMATED SCHOOL BUS SAFETY AND SECURITY USING IOT AND CLOUD

School bus services now play an important role in transporting students from their homes to schools in every country region. Many parents rely heavily on school bus services, despite their concerns about their children's safety. As a result of this difficulty, this paper proposed an SMS-based solution to help most parents track their children's school bus movements (in/out). Parents will receive an SMS once their children have boarded the bus and arrived at their destination. Using RFID and GSM technology, the system strives to create a school bus security system. RFID is used to authenticate the student's identity to the parent's phone number and to count the number of students in the bus, whereas GSM is deployed as a platform to send SMS notifications to parents about their children's whereabouts. The microcontroller is coupled to RFID and GSM technologies, with the visual studio application deployed in AWS cloud controlling both the microcontroller and the operations. According to the system, the developed project is capable of allows both parents and school administration control and monitor a variety of aspects such as the number of children on bus, each student's details, pick-up and drop-off times, location, and attendance system. A web application allows parents to keep track of the school bus's whereabouts as well as the student's pick-up and drop-off times. In short, this prototype system could provide peace of mind to most parents who entrust their children to the school bus transportation system.
