A modification of DYMO routing protocol with knowledge of nodes’ position: proposal and evaluation
(Springer, 2015)
Conference report
Restricted access - publisher's policyKnowledge of the physical location of the nodes is known to improve performance in wireless networks. This is especially true in MANETs, where routing protocols face a continuously changing topology. In the past, routing ... -
A New CAC Policy Based on Traffic Characterization in Cellular Networks
(Springer, 2008-05)
Conference report
Open AccessThe Call Admission Control (CAC) method presented in this paper is based on the statistical properties of the network’s traffic variables. It probabilistically estimates the time until the release of a seized channel: the ... -
A ranging method with IEEE 802.11 data frames for indoor localization
(IEEE, 2007-03-15)
Conference lecture
Open AccessIEEE 802.11 networks constitute a suitable infrastructure for accurate indoor positioning. However, existing approaches based on fingerprinting present drawbacks that make them not suitable for most of applications. This ... -
A software platform for measuring distances through round trip time in IEEE 802.11
(IEEE Computer Society Publications, 2013)
Conference report
Restricted access - publisher's policyIndoor positioning has focused the interest of researchers for years. Although there are several techniques proposed, they are difficult to reproduce and consequently to contrast and improve. This paper presents a modular ... -
A survey of routing protocols for energy constrained ad hoc wireless networks
(IEEE, 2007-12)
Conference report
Open AccessIn this survey we review energy-aware routing protocols for wireless multihop ad hoc networks and critically discuss the main results in this area. The classification presented is in no case unique but summarizes the chief ... -
A topic on simulation in telecommunications engineering
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference report
Restricted access - publisher's policyTopics on network simulation are often offered as elective topics or short seminars of programs on computer sciences and telecommunications engineering. In other programs simulation is offered as part of a general core ... -
A user space implementation of the AODVv2 routing protocol
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessAd hoc On Demand Distance Vector Routing (AODV) protocol is a reactive MANET routing protocol frequently used as reference for either developing new ad hoc routing protocols or performance assessment purposes. Although it ... -
An engineering approximation for the mean waiting time in the M/H2b/s queue
(INOC, 2003-10-27)
Conference report
Open AccessAlthough the exact solution for the mean waiting time in the M/H2/s queue exists, it requires advanced programming skills and processing capacity. In most engineering problems the offered traffic and its features are known ... -
Channel Holding Time Distribution in Public Cellular Telephony
(Elsevier Science B.V., 1999-06)
Conference lecture
Open AccessThis paper examines the channel holding time of public cellular telephony systems. This is the time that the Mobile Station (MS) remains in the same cell, a fraction of the call holding time. The study is based on actual ... -
Chapter 4: Mobility Support
(SPRINGER-VERLAG., 2009)
Part of book or chapter of book
Restricted access - publisher's policyWireless access allows independency between the user’s position and the physical bearer used to access services from the network. However, this independency does not imply that wireless networks show a full ability to cope ... -
Collaborative positioning in ad hoc networks using passive time-differences of arrival
(Bentham Science Publishers, 2015-04-08)
Article
Restricted access - publisher's policyAccuracy and scalability contribute to the quality of location solutions in wireless networks. While accuracy is a parameter addressed in all location technologies, scalability is often relegated. However, scalability ... -
