Relay selection mechanism for cooperative communications using a game-theoretic approach

Abstract

We propose in this paper a new mechanism for selecting a most suitable partner in a cooperative wireless communication system, using a type of game called the Bidding game. In this game, in which the conventional theories of economic bidding are applied, the cooperative communication network is modeled as a single-user, multi-relay system in which the source acts as the auctioneer while the relays or partners act as the bidders in the game. The resource being auctioned here is power, and the relay which offers the highest bid in terms of price is selected and allocated power by the source node. Our findings show that there is a linear relationship between the utility achievable by a source node and the selection of a suitable partner for the cooperative process by that node. Our simulation also shows that the proximity of a relay node to the source node has an effect on the selectability of the node prior to the bidding.

“…Game theory and auctioning were some of the approaches used for relay selection. In [23] a bidding game is used for selecting a most suitable partner in a cooperative wireless communication system. The source acts as the auctioneer while the relays or partners act as the bidders in the game.…”

Game‐theoretic modeling and analysis of relay selection in cooperative wireless networks

“…Particularly, the authors model the relay selection of network nodes as an exchange market game and propose an algorithm for cooperation maintenance. Relay selection in a single‐source, multi‐relay network has been modeled as a bidding game in , where the authors show that a linear relationship exists between the utility achievable by a source node and the relay selection process. In , a relay assignment game in multi‐source multi‐relay wireless networks is studied.…”
