A DRAM/SRAM memory scheme for fast packet buffers
(2006-05)
Article
Open AccessWe address the design of high-speed packet buffers for Internet routers. We use a general DRAM/SRAM architecture for which previous proposals can be seen as particular cases. For this architecture, large SRAMs are needed ... -
A lightweight service placement approach for community network micro-clouds
(2019-03)
Article
Open AccessCommunity networks (CNs) have gained momentum in the last few years with the increasing number of spontaneously deployed WiFi hotspots and home networks. These networks, owned and managed by volunteers, offer various ... -
A new multicast opportunistic routing protocol for wireless mesh networks
(Springer, 2011)
Conference report
Open AccessOpportunistic Routing (OR) has been proposed to improve the efficiency of unicast protocols in wireless networks. In contrast to traditional routing, instead of preselecting a single specific node to be the next-hop ... -
A realistic open-data-based cost model for wireless backhaul networks in rural areas
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessBroadband Internet provision is an increasing demand in many rural areas and wireless internet service providers have emerged as an opportunity to fill this need. However, this type of operator typically consists of a small ... -
A technological overview of the guifi.net community network
(2015-12-24)
Article
Open AccessThis work presents a technological analysis of guifi.net, a free, neutral, and open-access community network. Guifi.net consists of more than 27,000 operational nodes, which makes it the world’s largest community network ... -
Adaptive channel assignment for wireless mesh networks using game theory
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
Conference report
Open AccessChannel assignment has been extensively researched for multi-radio wireless mesh networks, but it is still very challenging when it comes to its implementation. In this paper we propose a semi-dynamic and distributed channel ... -
Analysis of guifi.net's topology: extension of results
(2012-05-04)
Research report
Open AccessThis report extends the analysis carried out in a previous work [1] about the topology of guifi.net wireless community network. The main objective is validating the topology generator proposed in [1] for guifi.net like ... -
Anomaly detection for fault detection in wireless community networks using machine learning
(Elsevier, 2023-03-15)
Article
Open AccessMachine learning has received increasing attention in computer science in recent years and many types of methods have been proposed. In computer networks, little attention has been paid to the use of ML for fault detection, ... -
Candidate selection algorithms in opportunistic routing based on distance progress
(2015-01-01)
Article
Open AccessOpportunistic routing (OR) is a new class of routing protocols that selects the next-hop forwarder on-the-fly. In contrast to traditionally routing, OR does not select a single node as the next-hop forwarder, but a set of ... -
Closed form transient solution of continuous time Markov chains through uniformization
(Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering (ICST), 2013)
Conference lecture
Open AccessThis paper derives a mapping between a close form transient solution of a continuous time Markov chain (CTMC), and a close form transient solution of one of its uniformized discrete time Markov chains. This result is used ... -
Design and implementation of high-performance memory systems for future packet buffers
(Institute of Electrical and Electronics Engineers (IEEE), 2003)
Conference report
Open AccessIn this paper, we address the design of a future high-speed router that supports line rates as high as OC-3072 (160 Gb/s), around one hundred ports and several service classes. Building such a high-speed router would raise ... -
Distance progress based opportunistic routing for wireless mesh networks
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference report
Restricted access - publisher's policyOpportunistic Routing (OR) has been proposed to improve the performance of multihop wireless networks by exploiting its broadcast nature. In contrast to traditional routing, where traffic is sent along pre-determined ... -
Enabling individually entrusted routing security for open and decentralized community networks
(Elsevier, 2018-10)
Article
Open AccessRouting in open and decentralized networks relies on cooperation. However, the participation of unknown nodes and node administrators pursuing heterogeneous trust and security goals is a challenge. Community-mesh networks ... -
Energy efficient cloud service provisioning: Keeping data center granularity in perspective
(2016-06)
Article
Open AccessThe cost of power and its associated delivery are becoming significant factors in the total expenditure of large-scale data centers. Numerous techniques have been proposed to address the energy efficiency issue in cloud ... -
Experimental evaluation of a wireless community mesh network
