Indeed, the lated works on dissemination of information in mobile Ad source controls the dissemination of the information in the hoc networks. Then we study the stability and the velocity network by sending an anti-packet, like a vaccine. We show of the delayed logistic equation which model the evolution that there exists a sufficient condition for stability of the in-of the information inside the network.
