Abstract: The problem of optimal signal transmission by the user when there is eavesdropping in a wireless network, by summarizing the results of P. K. Gopala, L. Lai, H. El Gamal in the case where a condition in the form of cost for an information transmission is superimposed on a signal transmission process, as well as in the case when the transmission process itself cannot occur simultaneously but over a certain number of time slots.

Keywords: wireless networks, secrecy Shannon capacity, eavesdropping, closed form solution, optimal strategies, non-linear programming.
