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, ...
Optimizing video quality in dense small-cell wireless networks with packet overhearing
(2014)
The heterogeneous wireless network (HetNet) paradigm is based on the deployment of low power small cell base stations (SCBS) close to the user in parallel with a macrocell BS (MBS) that provides umbrella coverage. However, ...
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 ...
Asymptotically optimal policies for wireless networks with rechargeable batteries
(2008)
We consider the problem of cross-layer resource allocation for single-hop, time-varying, wireless networks operating with rechargeable batteries under general arrival, channel and recharge processes. The objective is to ...
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 ...
The effect of caching in sustainability of large wireless networks
(2012)
We study the scalability of multihop wireless communications, a major concern in networking, for the case that users access content cached across the nodes. In contrast to the standard paradigm of randomly selected ...
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 ...
Video-aware relay selection in single-carrier and OFDM wireless systems
(2014)
In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ...
