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 ...

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 ...

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 ...

Development of energy-efficient protocols and algorithms requires in-depth understanding of the power consumption characteristics of real world devices. To this aim, energy efficiency analysis is performed by the research community, mainly focusing on ...

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 ...

Smartphones and WiFi networks are becoming pervasive. As a result, new applications and services are being offered to smartphone users through WiFi networks. Some of the more novel applications provide data services to pedestrians as they move through ...

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 ...

Development of energy-efficient protocols and algorithms requires in-depth understanding of the power consumption characteristics of real world devices. To this aim, energy efficiency analysis is performed by the research community, mainly focusing on ...

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-...

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 ...

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 ...

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 ...

It is our great pleasure to welcome you to the 8th ACM International Workshop on Wireless Network Testbeds, Experimental evaluation & Characterization (WiNTECH 2013) hosted in Miami, Florida, USA. Similar to previous editions, WiNTECH workshop is ...
