RLNC in Practical Wireless Networks

چکیده
In this paper, we investigate random linear network coding (RLNC) in practical wireless networks. First we apply RLNC in the legacy network (wireless LAN mesh network) of multiple unicasts by the global RLNC. In the simulation results, in the system with the global RLNC, the network load and the power consumption is reduced for the simple topologies. However, the global RLNC cannot be applied to practical network by the decoding failure due to the various direction of each flow in the network. In this paper, we also discuss practical issues such as the hidden node problem, the occurrence of coding opportunity, and the RLNC overhead for RLNC in the wireless network.

متن کاملCharacterization of Random Linear Network Coding with Application to Broadcast Optimization in Intermittently Connected Networks
We address the problem of optimizing the throughput of network coded traffic in mobile networks operating in challenging environments where connectivity is intermittent and locally available memory space is limited. Random linear network coding (RLNC) is shown to be equivalent (across all possible initial conditions) to a random message selection strategy where nodes are able to exchange buffer...
متن کاملRobust video multicast with joint network coding and video interleaving
In this work, we propose a cross-layer solution to robust video multicast in erasure networks based on random linear network coding (RLNC) in the network layer and video interleaving (VI) in the application layer, and call it the joint RLNC-VI scheme. In the RLNC implementation, we partition one video coding unit (VCU) into several priority levels using scalable properties of H.264/SVC video. P...
متن کاملSystematic network coding for two-hop lossy transmissions
In this paper, we consider network transmissions over a single or multiple parallel two-hop lossy paths. These scenarios occur in applications such as sensor networks or WiFi offloading. Random linear network coding (RLNC), where previously received packets are re-encoded at intermediate nodes and forwarded, is known to be a capacity-achieving approach for these networks. However, a major drawb...
متن کاملEfficient and Reliable Communication in Wireless Relay Networks Using Joint Network Channel Fountain
—In the past few years, joint network-channel coding (JNCC) has drawn significant attention for reliable data communication in wireless network. However, it appears that fixed-rate channel coding is ineffective to make the outage probability to zero without having precise channel state information at the transmitter. To enhance the link robustness and the system throughput, this paper presents...
