Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)
Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ...
A new slicing scheme for efficient use of wireless testbeds
(2009)
The gradually growing need for testbed use so as networking algorithms to be validated in real environments, has given rise to optimal utilization of testbed resources. Despite the fact that, many laboratories around the ...
TLQAP: A topology and link quality assessment protocol for efficient node allocation on wireless testbeds
(2009)
In this paper we present Topology and Link Quality Assessment Protocol (TLQAP), which we have implemented as a wireless testbed management framework component, that is used to inspect link quality between wireless testbed ...
Routing-aware channel selection in multi-radio mesh networks
(2009)
Efficient channel selection is essential in 802.11 mesh deployments, for minimizing contention and interference among co-channel devices and thereby supporting a plurality of QoS-sensitive applications. In this paper, we ...
Cooperative handoff in wireless networks
(2008)
In 802.11-based wireless networks the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes the STAs get information about the active APs in their ...
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)
Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ...
Online assessment of sensing performance in experimental spectrum sensing platforms
(2014)
Dynamic Spectrum Access aims at exploiting underutilized frequency bands towards improving wireless network performance. In this context, spectrum sensing is employed, in order to monitor spectrum occupancy and drive ...
Experimenting with P2P traffic optimization for wireless mesh networks in a federated OMF-PlanetLab environment
(2011)
The ultimate success of the Wireless Mesh Network paradigm (WMN) in large scale deployments depends on the ability to test it in real world scenarios. A typical application scenario which is worth to be investigated in ...
New channel allocation techniques for power efficient WiFi networks
(2010)
Energy efficiency becomes evergreen than ever before. Over the last few years a significant research in wireless communications, aiming to enhance communications efficiency subject to constraint of power consumption, has ...
Towards the efficient performance of LTE-A systems: Implementing a cell planning framework based on cognitive sensing
(2014)
LTE and LTE-A have dominated as a 4G enabler protocol, adopted by the majority of the network providers worldwide. The efficient performance of an LTE network relies on the selected frequency within an operating band that ...
