Exchanging Third-Party Information With Minimum Transmission Cost

In this paper, the authors consider the problem of minimizing the total transmission cost for exchanging channel state information. They proposed a network coded cooperative data exchange scheme, such that the total transmission cost is minimized while each client can decode all the channel information held by all other clients. In this paper, they first derive a necessary and sufficient condition for a feasible transmission. Based on the derived condition, there exists a feasible code design to guarantee that each client can decode the complete information. They further formulate the problem of minimizing the total transmission cost as an integer linear programming.
