SAT05-3: Performance Evaluation of Sink Selection Techniques in Satellite Sensor Networks

Recent environmental monitoring systems are based on Satellite-based Sensor Networks (SSN) where earth stations (Sinks) gather messages from sensors and use the satellite channel to send sensible information to remote monitoring sites. In these systems, the Sink selection process may play a crucial role and needs to be investigated. The work includes: an introduction of the SSN scenario considered; a brief description of the Sink selection method aimed at guaranteeing the optimization of the energy consumption and, simultaneously, of the message transfer delay; a deep performance investigation, which represents the main contribution of this paper, carried out by simulation, of the studied technique.
