Research on Static Game Theory Based Secure Routing Algorithm in WSN

In deep research and analysis on WSN security routing protocols and according to the rational development trend of the sensor nodes, this paper proposes a new WSN security routing protocol based on the theory of the static game—GBR. GBR describes the interactions in a static game model using rational characteristics of nodes. When selecting the forwarding node, neighboring nodes decide whether to participate in forwarding data through game, and prevent the destruction of malicious nodes by calculating the utility function. They control and adjust the game process and results through incentive mechanism. GBR (Game theory Based Routing algorithm) reduces packet loss rate by the above mechanisms and strategies and effectively controls the self-ish behavior of nodes. In addition, GBR pursues security routing and makes design and improvement in the energy conservation, which considers node security and regards the energy of the nodes as an importing reference index, in order to balance the network energy consumption.
