This presentation will propose new mechanisms for locating a non-mobile transmitter in wireless communication or sensor networks. They rely on a set of trusted cooperative receivers that are able to measure the residual strengths of the received signals from the transmitter. These mechanisms cannot rely on the information provided by the transmitter since the latter can be malicious. The difficulty comes for the fact that no good approximation of the difference of two lognormal variables exists. Thus, we propose new algorithms that rely either on better approximations or a geometric interpretation of the problem.
