—In this paper, we experiment on a GNU radio based platform a point to multipoint transport protocol specifically designed for cognitive radio environments. Over a dedicated software defined based platform deployed in our premises we investigate two main functionalities of transport protocols in terms of reliability and congestion control. Comparing with(More)
— In this paper, we evaluate over a software defined radio testbed the performance of a DTN implementation in cognitive radio networks. Our experimental platform uses USRP devices operated by the GNU radio platform for physical and MAC layers operations. Over the deployed software archietcture, we have compared 2 existing DTN implementations then run a set(More)
Full-duplex transmission is an attractive air interface technology to improve spectral efficiency in future wireless systems. This paper introduces potential use cases for full-duplex transmission in small area radio communication systems, and evaluates the achievable performance gains of full-duplex transmission over half-duplex transmission in different(More)
—To meet the growing local and distributed computing needs, the cloud is now descending to the network edge and sometimes to user equipments. This approach aims at distributing computing, data processing, and networking services closer to the end users. Instead of concentrating data and computation in a small number of large clouds, many edge systems are(More)
In this paper, we propose a new MAC protocol targeting bidirectional full duplex wireless networks. Our solution reserves resources and adapts frame sizes based on the handshake between communicating nodes. Most importantly, our protocol requires minor changes for backward compatibility with IEEE 802.11 protocol. We have implemented and simulated our(More)
Spanning several frequencies, cognitive radios support dynamic management of the rate vs. range requirements of new generation tactical radio networks. We exploit this agility to offer point to multipoint transport implementing group communication for data services in the network. The key feature of our proposed transport protocol (PMT) resides in its(More)
