Hybrid FSO–Satellite Architecture for Remote Monitoring Networks: Analysis and Evaluation
Аннотация
Remote sensing of objects in remote locations with poor geographical topography entails the need to employ credible, high capacity, information exchange as well as employing communication infrastructure using energy efficient network equipment. This paper suggests a hybrid network design that will utilize both free as well as space optical (FSO) communications and satellite networks to eliminate these constraints. The hybrid architecture takes advantage of fast FSO network and satellite fragments in order to form a large communication area in different unfavorable weather conditions so that the transmission and reception of communication signals can remain stable at a distance throughout the entire chain during remote monitoring. Performance indicators were used to test the reliability of the proposal and these include channel bandwidth, communication-signal delay time, packet delivery rate, bit error rate, and signal-to-noise ratio. The SNR or BER model was used to evaluate the state of communication channel (fading, FSPL and AWGN) of each packet transmitted and the likelihood of a successful delivery of a packet based on the simulation study results conducted using Matlab.
