A Method of Proactive MANET Routing Protocol Evaluation Applied to the OLSR Protocol
DA SILVA, LUIZ (2011)Traditional evaluation studies of MANET routing protocols have concentrated on quantitative, traffic-based metrics like throughput and packet loss. These metrics provide a lim- ited evaluation of protocol performance ... -
Modelling Multi-operator Base Station Deployment Patterns in Cellular Networks
KIBILDA, JACEK; DA SILVA, LUIZ (2016) -
On Resource Reuse for Cellular Networks with Femto- and Macrocells Coexistence
DA SILVA, LUIZ (2010)This paper studies downlink resource reuse schemes for cellular networks with coexisting femtocells and macrocells. We examine two reuse schemes, termed split reuse and shared reuse. In this paper, we develop an analytical ... -
On Selfish and Altruistic Coalition Formation in Cognitive Radio Networks
DA SILVA, LUIZ (IEEE, 2010)We formulate the sensing-throughput tradeoff problem for distributed cognitive radio (CR) networks as a coalition formation game. Formation of coalitions enables the CRs to increase their achievable throughput, under the ... -
On Software Tools and Stack Architectures for Wireless Network Experiments
DA SILVA, LUIZ (2011)Simulation is still the most widely adopted perfor- mance evaluation technique in mobile ad hoc network research, in spite of a growing number of questions about the fidelity of this technique. Implementation-based ... -
The Price of Ignorance: Distributed Topology Control in Cognitive Networks
DA SILVA, LUIZ (2010)In a cognitive network, autonomous and adaptive radios select their operating parameters to achieve individual and network-wide goals. The effectiveness of these adaptations depends on the amount of knowledge about the ... -
Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
DA SILVA, LUIZ; MARCHETTI, NICOLA (2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ... -
Radio Access Network and Spectrum Sharing in Mobile Networks: A Stochastic Geometry Perspective
KIBILDA, JACEK; DA SILVA, LUIZ (2017) -
Rendezvous for Cognitive Radios
DA SILVA, LUIZ (2011)Cognitive radios have been touted as a solution to communicating in a Dynamic Spectrum Access environment. This paper examines how cognitive radios initially find one another among the expanse of ever-changing open spectrum, ... -
Sensitivity Analysis on Service-Driven Network Planning
KIBILDA, JACEK; DA SILVA, LUIZ (2017) -
Spectrum without Bounds, Networks without Borders
DA SILVA, LUIZ; DOYLE, LINDA; FORDE, TIM (IEEE, 2014)The purpose of this paper is to present a vision for future mobile and wireless networks. The vision, which we call Networks without Borders (NwoB), is based on a market-place of virtual network operators which construct ... -
Testbed Federation: An Approach for Experimentation-driven Research in Cognitive Radios and Cognitive Networking
DA SILVA, LUIZ (2011)The sub-optimal exploitation of radio spectrum is widely accepted. Cognitive radio is a technol ogy that aims to address this issue and improve the overall efficiency of radio spectrum utiliza tion. However, this ... -
Throughput-Efficient Dynamic Coalition Formation in Distributed Cognitive Radio Networks
DA SILVA, LUIZ (2010)We formulate the problem of distributed throughput-efficient sensing in cognitive radio (CR) networks as a dynamic coalition formation game based on a Markovian model. The proposed coalition formation enables the CRs to ... -
Traffic-Aware Channel Assignment for Multi-Radio Wireless Networks
DA SILVA, LUIZ (2012)This paper studies channel assignment in multi-hop wireless networks in which nodes are equipped with multiple radios, each of which can be assigned to a channel. We argue for an approach that rst assigns channels ... -
Vehicular Networks: Embracing Wireless Heterogeneous Communications through Vertical Handover
DA SILVA, LUIZ (2013)By taking advantage of the ever growing deployment of wireless networks, the automotive industry is increasingly enabling vehicles to communicate with one another and with the infrastructure, with benefits to information ... -
Whitespace Networks Relying on Dynamic Control Channels
DA SILVA, LUIZ; NOLAN, KEITH (2013)The emergence of whitespace networks, and whitespace communications in general, provides an opportunity to, at least partially, meet the ever-growing demand for mobile data communication. Most of the whitespace network ...
