A game theoretical approach to the management of node clusters in DR-OSTC based MISO cooperative communications

In this paper, the problem of node management in cooperative transmissions exploiting Distributed Randomized - Orthogonal Space Time Coding (DR-OSTC) schemes is tackled. In particular, resorting to game theory, a novel strategy able to manage node participation in a distributed cooperative link using a simple randomized coding rule is derived. The proposed solution guarantees the participation of a proper number of nodes to a virtual antenna array (hence avoiding an energy waste) without requiring any overhead for node management.
