Together with recent advancements in Radio Access Network (RAN) technologies, Wi-Fi is expected to be at the center of research on the subject of ubiquitous wireless connectivity, towards building the new 5G ecosystem. Nevertheless, the necessary testbed infrastructure to support large scale experimentally driven research seems to be missing. In this work we present the design and implementation of...
Wireless technologies have evolved rapidly over the past years, directly affecting our everyday living with the wide penetration of smart mobile devices. As such, the research community has placed major efforts in shaping and forming the future wireless technologies for enhanced end-user experience. Nevertheless, protocols and algorithms over wireless networks are better evaluated in real world scenarios,...
Experimental platforms (testbeds) play a significant role in the evaluation of new and existing technologies. Their popularity has been raised lately as more and more researchers prefer experimentation over simulation as a way for acquiring more accurate results. This imposes significant challenges in testbed operators since an efficient mechanism is needed to manage the testbed's resources and provision...
In this paper we present the NITOS Bikes Net platform, a city-scale mobile sensing infrastructure that relies on bicycles of volunteer users. NITOS Bikes Net employs a custom-built embedded node that can be equipped with different types of sensors, and which can be easily mounted on a bicycle in order to opportunistically collect environmental and WiFi measurements in different parts of the city....
In this paper we present NITOS Bikes Net, a framework for mobile sensing in a city-wide environment offering experimentation capabilities. More Specifically, we present a custom-made and modular prototype device that can be easily mounted on volunteers' bicycles dedicated to collecting environmental measurements and available WiFi networks. In addition, we present our enhancements in OMF framework...
