Abstract: Aiming at the security and limited energy issues in wireless sensor network, this paper introduces a secure and energy-saving routing protocol based on cooperative game strategy. A novel incentive mechanism is proposed: all the nodes including the selfish ones are encouraged to forward packets and are rewarded if they help a cooperative sender or are punished if they help a non-cooperative one. All the nodes are motivated to maintain a good reputation so that their packets could be treated well by other relays. A relay node can decide its willingness to cooperate for its own benefits, and a sender selects the suitable relay that can maximise its payoff. Simulation results demonstrate that the proposed scheme turns the non-cooperative nodes into cooperative ones, offers a higher throughput and can prolong the lifetime of the network.
