With the ubiquity of mobile appliances, efficient wireless access has become an urgent need for mobile users. Efficient wireless access requires accurate radio signal maps. Unfortunately, most of solutions could not be applied to large-scale urban space. Crowdsensing schemes could leverage the smartphone to sense WiFi signals, but could not provide accurate map because of the intolerable noises in...
Personal mobile devices are nowadays so pervasive that a broad range of novel learning practices and paradigms can profitably exploits them. Mobile Crowd Sensing (MCS) is one of them. In MCS, mobiles act as data sources for monitoring tasks (e.g., traffic planning, air pollution monitoring, emergency management), thanks to their computational capability and their embedded sensors. From a pedagogical...
With the ubiquity of WiFi-enabled smartphones, and large-scale access point deployment, WiFi-based localization is one of the most promising indoor localization systems. Existing WiFi localization solutions, however, exhibit high power demand due to the periodic updates required, which raises the barrier for deployment on mobile devices since battery life is a crucial resource. In this paper, we present...
The wide deployment of Wireless Local Area Networks (WLAN) we are witnessing today increases connectivity opportunities for mobile terminal devices, such as smartphones. However, continuous scanning for WLAN points of attachment can be a power exhausting mechanism for such battery-powered devices. These mobile devices, besides being equipped with different wireless access interfaces, are also coupled...
ldquoParticipatory sensingrdquo is an exciting new paradigm where people voluntarily sense their local environment and share this data using mobile phones and the Internet. It can revolutionize applications such as intelligent transportation, public health and social networking. However, a major concern is the amount of trust that can be placed in the shared data. We address this concern in our demonstration...
