Enhanced node cooperation mechanism based on game theory in wireless ad hoc networks
Xiao-Hua Yu, Qiong Liu · 2016
In order to stimulate node to cooperate in packet forwarding of other nodes in wireless ad hoc networks, a game model is presented for the interaction between nodes, which can promote the probability of cooperation. The exchange mechanism has no use for additional exploration information, preventing the use of observational error-sensitive trigger strategy, saving energy and network bandwidth. The proposed scheme employs a modified sequential equilibrium strategy to ensure coordination between nodes by comparing with the existing mechanisms through simulation. The simulation results show that it can improve packet delivery ratio, enhance cooperation ratio between nodes and increase average income.
