The case for structured random codes in network capacity theorems
Random coding arguments are the backbone of most channel capacity achievability proofs. In this paper, we show that in their standard form, such arguments are insufficient for proving some network capacity theorems: structured coding arguments, such as random linear or lattice codes, attain higher rates. Historically, structured codes have been studied as a stepping stone to practical construct...
متن کاملظرفیت شبکه های حذفی تحت کدینگ فضایی شبکه
We study the capacity of point-to-point erasure networks under a restricted form of network coding to which we refer as spatial network coding. In this form of coding, the nodes can not perform coding on successive packets which are received from one incoming link. The coding at a node is restricted to the packets received at the same time slot from different incoming links...
متن کاملReliable Flow Control Coding in Low-Buffer Grid Networks
We consider a grid network where nodes contain small buffers. A packet that faces a crowded buffer in its route will get extra latency and may be dropped. In this paper, we propose a novel flow control protocol called RFCC for grid networks. RFCC tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

متن کاملNested linear/Lattice codes for structured multiterminal binning
Network information theory promises high gains over simple point-to-point communication techniques, at the cost of higher complexity. However, lack of structured coding schemes limited the practical application of these concepts so far. One of the basic elements of a network code is the binning scheme. Wyner and other researchers proposed various forms of coset codes for efficient binning, yet ...
