In recent times, there is increasing consensus that the traditional Internet architecture needs
to be evolved for it to sustain unstinted growth and innovation. A major reason for the …

Programmable wireless platforms aim at responding to the quest for wireless access
flexibility and adaptability. This paper introduces the notion of wireless MAC processors …

Self-organizing networks able to adapt to changes in the environment have already been a
longstanding research topic. Given the limited number of license-free industrial, scientific …

We consider a multichannel Cognitive Radio Network (CRN), where secondary users
sequentially sense channels for opportunistic spectrum access. In this scenario, the Channel …

We introduce MAClets, software programs uploaded and executed on-demand over
wireless cards, and devised to change the card's real-time medium access control operation …

Cognitive radios are becoming the technological foundation for efficiently managing the
scarcity of wireless spectrum, fulfilling various QoS demands and allowing different networks …

Cognitive MAC protocols are designed to efficiently utilize the spectral resources without
affecting the performance characteristics of the primary users. The use of spectrum …

Timing is a key issue in many wireless, lower-layer (eg, physical and data link layer)
communication protocols. Maintaining time-critical behavior while increasing MAC protocol …

Cognitive radios require fast reconfiguration of the protocol stack for dynamic spectrum
access and run-time performance optimization. In order to provide rapid on-the-fly …

This demo presents WiMAC, a general-purpose wireless testbed for researchers to quickly
prototype a wide variety of real-time MAC protocols for wireless networks. As the interface …
