Network Coding for Line Networks with Broadcast Channels
An achievable rate region for line networks with edge and node capacity constraints and broadcast channels (BCs) is derived. The region is shown to be the capacity region if the BCs are orthogonal, deterministic, physically degraded, or packet erasure with one-bit feedback. If the BCs are physically degraded with additive Gaussian noise then independent Gaussian inputs achieve capacity.
متن کاملNear Optimal Broadcast with Network Coding in Large Sensor Networks
We study efficient broadcasting for wireless sensor networks, with network coding. We address this issue for homogeneous sensor networks in the plane. Our results are based on a simple principle (IREN/IRON), which sets the same rate on most of the nodes (wireless links) of the network. With this rate selection, we give a value of the maximum achievable broadcast rate of the source: our central ...
متن کاملSystematic Network Coding for Lossy Line Networks
This dissertation focuses on packet-level systematic network coding (SNC) schemes to provide resilience to packet losses in lossy line networks. In theory, network coding is known to improve throughput and reliability of lossy networks. However, the translation of the network coding theory into efficient practical network coding solutions involves some critical challenges. This dissertation add...
متن کاملOn Superposition Coding for Wireless Broadcast Channels
This thesis investigates the performance of broadcast systems in which the transmitted signal is obtained by superposition of the independent user signals. We first focus on single-input single-output systems in additive white Gaussian noise channel. We study the performance of a superposition coding based transmission scheme for a 2-user broadcast system when the power allocated to each user i...
متن کاملRandom coding theorem for broadcast channels with degraded components
Absfroct-This paper generalizes Cover’s results on broadcast channels with two binary symmetr ic channels (BSC) to the class of degraded channels with N components. A random code, and its associated decoding scheme, is shown to have expected probability of error going to zero for all components simultaneously as the codeword length goes to infinity, if the point representing the rates to the va...
