Mobile video consumption establishes as a massively growing
market. To guarantee an acceptable quality of experience
to the end user, current studies try to improve data
transmissions on air interfaces. However, the bottleneck in
cellular mobile networks is the traversal of the infrastructure.
A paradigm to circumvent this fact and to increase
the system’s capacity is given by device-to-device communication
in combination with proximity detection. Those
networks promise scalability and performance improvements
in utilizing scarce resources. This principle is easy to integrate
into an existing mobile peer-to-peer video streaming
system. In this study, we present measurements on application
level to determine the performance that a smart device
contributes to different wireless networks. The results outline
that content uploading from smart devices is negligible
in cellular networks, but shows acceptable performance in
WiFi networks. This evaluation is the foundation to build a
proximity enhanced video streaming system for mobile devices.
