Abstract

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 was proposed in this paper. The punishment mechanism was used both in a common control channel and a data channel. 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. Index Terms - security protocol, UWB, WiFi, interference
