LEO and GEO protocol models differ sharply in latency, handover timing, Doppler effects, and link budgets. Effective simulations capture orbital dynamics to compare throughput, resilience, and QoS under realistic traffic loads.

WebRTC minimizes latency with peer-to-peer media paths and adaptive bitrate, while MQTT scales high-traffic messaging through lightweight publish/subscribe delivery and efficient broker-based routing.

Implementing Zero-Trust in simulated SDNs requires continuous identity verification, micro-segmentation, and policy-driven traffic control to reduce lateral movement and validate every network interaction.

QUIC cuts latency with 0-RTT setup, multiplexed streams, and built-in TLS, while TCP/IP remains reliable but slower under loss. For cloud apps, QUIC often improves responsiveness at scale.

6G protocol simulation enables engineers to test ultra-low latency, AI-native networking, and terahertz communication in virtual environments, reducing risk while accelerating future-ready connectivity design.
