An Approach to Multisource-Multicast Problem using Linear Network Code
Shigeki Miyake (NTT) IT2012-77 ISEC2012-95 WBS2012-63
Abstract (in Japanese) (See Japanese page) 
(in English) When network coding is applied to multicast problem
that consists of one source and multi sinks,
the maximum value of transmission rate with which receivers
can decode transmitted message correctly
was obtained using cutset bound.
The multicast problem treating more than one sources
that is called multisource-multicast problem
becomes more difficult.
We investigate admissible conditions
for 2-unicast, K-unicast and multisource-multicast problems
using linear network code,
and derive admissible rate regions using scalar network code.
Furthermore, when block network code is used,
an example shows that
the admissible rate region can become larger than that using
scalar linear network code,
and outer region of the admissible rate region for block network code
is evaluated.
