线性编码下线性确定性网络的互易性

Reciprocity in Linear Deterministic Networks under Linear Coding

Adnan Raja, Vinod M. Prabhakaran, Pramod Viswanath

摘要:

线性确定性模型最近已被用于获得许多无线通信网络问题的一阶理解。在许多这样的情况下,人们已经指出,网络的容量区域和它的对等区域(其中通信链路是反向的,源和目的地的角色是交换的)是相同的。在本文中,我们考虑一个线性确定性通信网络与多个单播信息流。对于这个模型,在线性编码类的限制下,我们证明了网络的速率区域和它的倒数是相同的。这可以被看作是有线网络的线性可逆性的推广,在网络编码文献中已经知道。

英文摘要:

The linear deterministic model has been used recently to get a first order understanding of many wireless communication network problems. In many of these cases, it has been pointed out that the capacity regions of the network and its reciprocal (where the communication links are reversed and the roles of the sources and the destinations are swapped) are the same. In this paper, we consider a linear deterministic communication network with multiple unicast information flows. For this model and under the restriction to the class of linear coding, we show that the rate regions for a network and its reciprocal are the same. This can be viewed as a generalization of the linear reversibility of wireline networks, already known in the network coding literature.
