Achievable bandwidth estimation for stations in multi-rate IEEE 802.11 WLAN cells
(2007-04-16)
Conference report
Open AccessThis paper analyzes the effect of multi-rate transmissions in a CSMA wireless LAN environment. Observations in a real testbed showed that bandwidth resources (in Bytes/s) are shared fairly among all stations even though ... -
A fault-tolerant algorithm for distributed resource allocation
(2017-11-01)
Article
Open AccessResource allocation is a usual problem that must be faced during a distributed system design. Despite the large number of algorithms proposed in literature to solve this problem, most papers lack of detailed descriptions ... -
A flexible protocol communications approach for a supervisory system
(Institute for Communication Technology Management (CTM), 1989)
Conference report
Open AccessThis paper deals with the communication protocol intended to control up to 1016 devices of a new supervisory system. It has been conceived in two complementary phases. The first one (Cycle-A) is intended to inform the ... -
A GA-based simulation system for WMNs: performance analysis for different WMN architectures considering transmission rate and OLRS protocol
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessIn this paper, we evaluate the performance of two WMN architectures considering throughput, delay, jitter and fairness index metrics. For simulations, we used ns-3. We compare the performance for two architectures considering ... -
A game theoretic trust model for on-line distributed evolution of cooperation in MANETs
(2011-01-13)
Article
Restricted access - publisher's policyCooperation among nodes is fundamental for the operation of mobile ad hoc networks(MANETs). In such networks, there could be selfish nodes that use resources from other nodes to send their packets but that do not offer ... -
A genetic algorithm-based system for Wireless Mesh Networks: analysis of system data considering different routing protocols and architectures
(Springer, 2016-07-01)
Article
Open AccessWireless mesh networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in ... -
A multi-agent adaptive protocol for femto-satellite applications
(Universitat Politècnica de Catalunya, 2011-07-15)
Bachelor thesis
Open AccessFemto-satellites are a very promising category of satellites that weigh less than 100 grams. Also, a Pico-Rover it is a self-contained robot that weighs less than 1 kilogram and its motion works by rolling the external ... -

Restricted access - author's decision[ANGLÈS] I have studied both Docsis 2.0 and Docsis 3.0 specification documents to: i) find out the similarities and differences between the two Docsis versions and, ii) to extend and analyze the Docsis 2.0 model to Docsis ... -
Analytical model of large data transactions in CoAP networks
(2014-08-01)
Article
Open AccessWe propose a novel analytical model to study fragmentation methods in wireless sensor networks adopting the Constrained Application Protocol (CoAP) and the IEEE 802.15.4 standard for medium access control (MAC). The blockwise ... -
Analytical resource optimization for DF relay-assisted transmission under HARQ
(IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
Conference report
Open AccessUnder limited channel state information at the transmitter the communication suffers from the outage events produced by a data rate selection not supported by the current channel realization. Automatic repeat request (ARQ) ... -
