Satellite Earth Station (SES) Selection Method for Satellite-based Sensor Networks

The reference network is composed of a group of wireless sensors directly in view of a Cluster of Satellite Earth Stations (CoSES), which convey the information coming from the sensors to a destination Remote Monitoring Host (RMH). More than one Satellite Earth Station (SES), all in this letter, within the cluster receive the information packets but to avoid wasting bandwidth and energy only one of them stores the packets coming from a specific sensor and forwards them to the destination through the satellite channel. This letter proposes a method to select the transmitting SES so to minimize the distance with a situation considered ideal for a set of metrics: packet loss rate, average communication delay, and average energy consumption
