Background: Distracted walking is a major cause of pedestrian fatalities. Along with the expansion and popularity of mobile phones, their impacts on pedestrian safety, especially when crossing urban intersections have attracted a lot of attention. The purpose of this study is to evaluate the effects of mobile-phone use on pedestrians’ crossing behavior when passing signalized intersections. Ma...

Social awareness and social ties are becoming increasingly popular with emerging mobile and handheld devices. Social trust degree describing the strength of the social ties has drawn lots of research interests in many fields in wireless communications, such as resource sharing, cooperative communication and so on. In this paper, we propose a hybrid cooperative beamforming and jamming scheme to ...

background: attendance management is one of the most important issues in the educational institutions. the traditional method for attendance recording is manually recording by professors in the school or university which is associated with several problems. we proposed the design and utilization of an electronic application for students’ attendance recording via smartphones and pcs. methods: th...

Radio-frequency (RF) energy harvesting (EH) in wireless relaying networks has attracted considerable recent interest, especially for supplying to relay nodes the Internet of Things (IoT) systems assist information exchange between a source and destination. Moreover, limited hardware, computational resources, availability IoT devices have raised various security challenges. To this end, physical...

In several wireless communication systems, robustness against jammers and covertness eavesdroppers are required simultaneously. this paper, we propose a novel covert anti-jamming system. The properties of both achieved through the Gaussian-coded time-frequency modulation scheme. We two receiver algorithms based on sparse signal recovery framework. estimate remove jamming from received signal. a...
