Abstract:
As one type of the attacks happening in MAC layer of wireless networks, a selfish behavior can degrade network performance significantly. In this paper, we studied a hybrid wireless network including UWB devices and WiFi devices together and analyze the characteristics of selfish behavior and the methods how to expose it. In order to improve the self-giving cooperation between the nodes in hybrid wireless networks and increase the fairness index of the whole networks, a security mechanism based on a puzzle model was proposed in this paper. The punishment mechanism was used both in a common control channel and a data channel. And then, we proposed an optimal algorithm to reduce the interference of networks. The results of stimulations show that the proposed protocol improves the self-giving cooperation between nodes in the networks and make the interference of the network minimum.
