Diseño de red de transporte convergente para redes de sensores inalámbricos y fotónicos

Abstract

This paper presents the design of a convergent optical transport architecture for wireless and photonic sensor networks, based on the existing optical transport network deployed in the city of Bogotá, Colombia. The proposed architecture is evaluated through the transport of services using subcarrier multiplexing, enabling the definition of different operating frequencies for RF, initially at 2.4 GHz, and support services such as WiFi, Bluetooth, Zigbee, SigFox, among others. The proposed design demonstrates high scalability given the distribution of the pre-existing network, allowing for its modification to incorporate both types of sensors: photonic (FBG) and wireless (RoF), in locations that will serve the multi-coverage area with significant historical, economic, cultural, and social relevance. The system exhibits optimal performance in terms of bit error rate (BER) and signal power within the multi-coverage area, considering various interference parameters such as SS-RSRP, SS-RSRQ, DL-SINR, and Throughput-DL.
