This paper casts recent accomplishments in the field of Wireless MAC programmability into the emerging Software Defined Networking perspective. We argue that an abstract (but formal) description of the MAC protocol logic in terms of extensible finite ...

Software Defined Radio (SDR) is a technology which facilitates experimentation and the practical realization of novel wireless communication systems. Especially low-cost SDRs, however, experience high communication delays due to the connection between ...

In this work, we consider the challenge of delivering high-quality multimedia content to users concentrated in a small physical location, e.g., a sports stadium in which fans may view extra video content on their mobile devices. Because each user ...

Micro Unmanned Aerial Vehicles (UAVs) employed in civil missions are receiving remarkable attention from both research and industry. UAVs embed more and more sensor technology, and their small mounted cameras allow for efficient mapping of large areas ...

Wireless/mobile video streaming has become increasingly popular, which makes wireless link bandwidth scarce. To provide streaming services to mobile users, it is crucial to adapt to the link condition and traffic fluctuation. We investigate which ...

Laboratory-based wireless testbeds are essential for performing repeatable experiments with experimental protocols and devices. Several many-to-many wireless emulators have been proposed and built, but existing systems still rely on simplified channel ...

It is well known that wireless channels produce higher bit error rates than wired connections. However, little knowledge exists about how bit errors are distributed within messages. In this paper, we present results from our experiments in an 802.15.4 ...

In this paper, we characterize the performance of HD video streaming in 802.11n WLANs under user mobility. We conducted experiments in QuRiNet, a large-scale outdoor wireless testbed that experiences little electromagnetic interference. We observe the ...

Wireless low-power embedded devices are populating indoor environments, where everyday activities drastically impact communication. We explore a statistical approach to identify changes to the communication links state during system operation. The long-...

Small-scale unmanned aerial vehicles (UAVs) have received high attention by the robotics community for delivering sensory data of limited size. Yet, the communication capabilities of off-the-shelf UAVs are insufficient for high volume data, such as ...

Participatory Sensing is the concept of distributed data collection by self-selected participants. By exploiting latest technology's smart devices, a large number of valuable information can be collected through embedded sensors and also be uploaded ...

Cognitive Radio paradigm (CR) is recognized as key enabler for next generation wireless networking: accessing the limited radio spectrum in an opportunistic manner allows secondary users to boost their transmission performance without interfering with ...

We demonstrate the use of SUNSET, a framework for seamless simulation, emulation and testing, through the implementation and validation of a novel time synchronization and localization algorithm for underwater acoustic sensor networks. The algorithm, ...

Residential users often face performance issues while using wired broadband connection with bandwidth hungry applications such as high-quality video streaming. Despite residential users have both wired (ADSL, cable, fibre) and wireless (3G, 4G) access ...

Evaluation of Content-Centric Networking (CCN) transport protocols, especially over wireless networks, brings about new requirements for testbeds. Typical CCN transport features such as hop-by-hop transfer, caching support, and receiver-driven traffic ...
