Hyukjoon Kwon, HyungJune Lee, and John M. Cioffi. Cooperative Strategy by Stackelberg Games under Energy Constraint in Multi-hop Relay Networks. Proc. of IEEE Globecom, 2009.
Abstract:
This paper presents a cooperative relay strategy
with a game-theoretic perspective. In multi-hop networks, each
node needs to send traffic via relay nodes, which behave
independently while staying aware of energy constraints. To
encourage a relay to forward the packets, the proposed scheme
formulates a Stackelberg game where two nodes sequentially bid
their willingness weights to cooperate for their own benefits.
Accordingly, all the nodes are encouraged to be cooperative only
if a sender is cooperative and alternatively to be non-cooperative
only if a sender is non-cooperative. This selective strategy changes
the reputations of nodes depending on the amount of their
bidding at each game and motivates them to maintain a good
reputation so that all their respective packets can be treated well
by other relays. This paper analyzes a Nash equilibrium from
the proposed scheme and validates a sequential-move game by
Stackelberg competition as opposed to a simultaneous-move game
by Cournot competition. Simulation results demonstrate that the
proposed scheme turns non-cooperative nodes into cooperative
nodes and increases the cooperative relaying stimulus all over
the nodes. Thus, every node forwards other packets with higher
probability, thereby achieving a higher overall payoff.
