Design, architecture and implementation of a resource discovery, reservation and provisioning framework for testbeds
(2015)
Experimental platforms (testbeds) play a significant role in the evaluation of new and existing technologies. Their popularity has been raised lately as more and more researchers prefer experimentation over simulation as ...
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, ...
An iterative double auction for mobile data offloading
(2013)
Mobile data offloading through complementary network technologies such as WiFi and femtocell can significantly alleviate network congestion and enhance users' QoS. In this paper we consider a market where mobile network ...
Demonstration of a Vehicle-to-Infrastructure (V2I) communication network featuring heterogeneous sensors and delay tolerant network capabilities
(2012)
The development of applications based over vehicular networks, such as road safety, environmental information etc. require a complete testbed platform for research and evaluation. Such a platform will be provided by NITOS[1] ...
Online energy consumption monitoring of wireless testbed infrastructure through the NITOS EMF framework
(2013)
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 ...

Asymptotic laws for content replication and delivery in wireless networks
(2012)
A key consideration in novel communication paradigms in multihop wireless networks regards the scalability of the network. We investigate the case of nodes making random requests on content stored in multiple replicas over ...
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 ...
Convex approximation algorithms for back-pressure power control of wireless multi-hop networks
(2011)
Cross-layer design and operation of wireless networks has attracted significant interest in the last decade, yet some basic problems in the area remain unsolved. In this paper, we consider the joint routing and power control ...
