In satellite-based sensor networks (SSN), earth stations represent the sink nodes of the sensor field and they may be simultaneously used to sent messages from the sensors to the remote monitoring hosts where data are stored and managed. In this environment, the choice of the sink may play a crucial role and represent a interesting field of investigation. The work includes: an introduction of the network scenario considered; a brief description of the sink selection methods aimed at guaranteeing the optimization of the energy consumption and, simultaneously, of the message transfer delay; a performance investigation of the proposals, which represents the main contribution of this paper, carried out by simulation
