Wireless Communication and Mobile Computing

This paper discusses the practical aspects of a wireless control system and reports the experience obtained from implementing a proof-of-concept system.

This is relevant because the nRF24L01+ radio system is a popular technology for the Internet- of-Things and for location- based services with wearable devices in smart cities.

In our project, public commuter buses carrying WLAN-enabled devices (mobile infostations) that provide DTN connectivity are used to ferry data between urban and rural areas.

In this paper, we present our wireless infostation and the cinema-in-a-back that we have built for the purpose and ready for a six-month long eld deployment in rural South Africa, in partnership with local institutions.

We call our technique EM-Sense and built a proof-of-concept smartwatch implementation.

In this work we propose using battery-free RFID sensor tags enhanced with on-board cameras to enable a network of distributed tags to optically determine the 3D location and pose of each camera tag given known reference tags enhanced with LEDs.

This paper explores how the IP stack and other networking protocols can be hosted on Linux-based VLC devices.

This work provides a method of wireless power transfer that uses the resonant modes of a metallic cavity to deliver power to a small dipole nearly anywhere within the structure.

We describe a low-complexity smart LED light bulb prototype that is based on existing consumer light bulbs and hence can be replicated without effort.

We introduce Acoustruments: low-cost, passive, and powerless mechanisms, made from plastic, that can bring rich, tangible functionality to handheld devices.
