XOR-based Source Routing
Jérôme Lacan, Emmanuel Lochin
We introduce a XOR-based source routing (XSR) scheme as a novel approach to enable fast forwarding and low-latency communications. XSR uses linear encoding operation to both 1)~bui…
Enhancing Satellite System Throughput Using Adaptive HARQ for Delay Tolerant Services in Mobile Communications
Rami Ali Ahmad, Jérôme Lacan, Fabrice Arnal +2
In this paper we propose the introduction of adaptive hybrid automatic repeat request (HARQ) in the context of mobile satellite communications. HARQ schemes which are commonly used…
Quasi-optimal grouping for broadcast systems with hierarchical modulation
Hugo Meric, José Piquer, Jérôme Lacan
Recently, we proposed to combine time sharing with hierarchical modulation to increase the transmission rate of broadcast systems. Our proposal involves to group the receivers in p…
On the Trade-off Between Spectrum Efficiency with Dedicated Access and Short End-to-End Transmission Delays with Random Access in DVB-RCS2
Nicolas Kuhn, Huyen-Chi Bui, Jerome Lacan +2
This paper analyses the performance of TCP over random and dedicated access methods in the context of DVB-RCS2. Random access methods introduce a lower connection delay compared to…
Physical Channel Access (PCA): Time and Frequency Access Methods Emulation in NS-2
Nicolas Kuhn, Olivier Mehani, Huyen-Chi Bui +3
We present an NS-2 module, Physical Channel Access (PCA), to simulate different access methods on a link shared with Multi-Frequency Time Division Multiple Access (MF-TDMA). This t…
Erasure Coding and Congestion Control for Interactive Real-Time Communication
Pierre-Ugo Tournoux, Tuan Tran Thai, Emmanuel Lochin +2
The use of real-time applications over the Internet is a challenging problem that the QoS epoch attempted to solve by proposing the DiffServ architecture. Today, the only existing…
CLIFT: a Cross-Layer InFormation Tool to perform cross-layer analysis based on real physical traces
N. Kuhn, E. Lochin, J. Lacan +3
Considering real physical (MAC/PHY) traces inside network simulations is a complex task that might lead to complex yet approximated models. However, realistic cross-layer analysis…
A Cooperative Network Coding Strategy for the Interference Relay Channel
Huyen-Chi Bui, Hugo Meric, Jerome Lacan +1
In this paper, we study an interference relay network with a satellite as relay. We propose a cooperative strategy based on physical layer network coding and superposition modulati…
Enabling Realistic Cross-Layer Analysis based on Satellite Physical Layer Traces
Nicolas Kuhn, Emmanuel Lochin, Jerome Lacan +3
We present a solution to evaluate the performance of transport protocols as a function of link layer reliability schemes (i.e. ARQ, FEC and Hybrid ARQ) applied to satellite physica…
Online multipath convolutional coding for real-time transmission
Tuan Tran Thai, Emmanuel Lochin, Jerome Lacan
Most of multipath multimedia streaming proposals use Forward Error Correction (FEC) approach to protect from packet losses. However, FEC does not sustain well burst of losses even…
Combining Adaptive Coding and Modulation with Hierarchical Modulation in Satcom Systems
Hugo Meric, Jérôme Lacan, Fabrice Arnal +2
We investigate the design of a broadcast system in order to maximise the throughput. This task is usually challenging due to the channel variability. Forty years ago, Cover introdu…
Improving broadcast channel rate using hierarchical modulation
Hugo Meric, Jérôme Lacan, Fabrice Arnal +2
We investigate the design of a broadcast system where the aim is to maximise the throughput. This task is usually challenging due to the channel variability. Modern satellite commu…
On-the-fly erasure coding for real-time video applications
Pierre-Ugo Tournoux, Emmanuel Lochin, Jerome Lacan +2
This paper introduces a robust point-to-point transmission scheme: Tetrys, that relies on a novel on-the-fly erasure coding concept which reduces the delay for recovering lost data…
On-the-Fly Coding to Enable Full Reliability Without Retransmission
Jerome Lacan, Emmanuel Lochin
This paper proposes a new reliability algorithm specifically useful when retransmission is either problematic or not possible. In case of multimedia or multicast communications and…
