HarborNet: A Real-World Testbed for Vehicular Networks
Carlos Ameixieira, André Cardote, Filipe Neves +9
We present a real-world testbed for research and development in vehicular networking that has been deployed successfully in the sea port of Leixões in Portugal. The testbed allows…
Geometry-Based Vehicle-to-Vehicle Channel Modeling for Large-Scale Simulation
Mate Boban, Joao Barros, Ozan K. Tonguz
Due to the dynamic nature of vehicular traffic and the road surroundings, vehicle-to-vehicle (V2V) propagation characteristics vary greatly on both small- and large-scale. Recent m…
TVR - Tall Vehicle Relaying in Vehicular Networks
Mate Boban, Rui Meireles, Joao Barros +2
Vehicle-to-Vehicle (V2V) communication is a core technology for enabling safety and non-safety applications in next generation Intelligent Transportation Systems. Due to relatively…
Modeling Network Coded TCP: Analysis of Throughput and Energy Cost
MinJi Kim, Thierry Klein, Emina Soljanin +2
We analyze the performance of TCP and TCP with network coding (TCP/NC) in lossy networks. We build upon the framework introduced by Padhye et al. and characterize the throughput be…
Trade-off between cost and goodput in wireless: Replacing transmitters with coding
MinJi Kim, Thierry Klein, Emina Soljanin +2
We study the cost of improving the goodput, or the useful data rate, to user in a wireless network. We measure the cost in terms of number of base stations, which is highly correla…
Techniques for Enhanced Physical-Layer Security
Pedro C. Pinto, Joao Barros, Moe Z. Win
Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of propagation channel…
Interfacing network coding with TCP: an implementation
Jay Kumar Sundararajan, Szymon Jakubczak, Muriel Medard +2
In previous work (`Network coding meets TCP') we proposed a new protocol that interfaces network coding with TCP by means of a coding layer between TCP and IP. Unlike the usual bat…
On Counteracting Byzantine Attacks in Network Coded Peer-to-Peer Networks
MinJi Kim, Luísa Lima, Fang Zhao +5
Random linear network coding can be used in peer-to-peer networks to increase the efficiency of content distribution and distributed storage. However, these systems are particularl…
An Algebraic Watchdog for Wireless Network Coding
MinJi Kim, Muriel Medard, Joao Barros +1
In this paper, we propose a scheme, called the "algebraic watchdog" for wireless network coding, in which nodes can detect malicious behaviors probabilistically, police their downs…
Network coding meets TCP
Jay Kumar Sundararajan, Devavrat Shah, Muriel Medard +2
We propose a mechanism that incorporates network coding into TCP with only minor changes to the protocol stack, thereby allowing incremental deployment. In our scheme, the source t…
