The increasing demand for robust communication systems in deep-
space exploration and satellite communications has highlighted the
limitations of traditional networking protocols. Delay/Disruption-
Tolerant Networking (DTN) emerges as a viable solution to address
intermittent connectivity, long propagation delays, and data loss in
such environments. Integrating DTN with a deep-space relay network
offers a strategic approach to enhancing connectivity for small
satellites, which are critical in modern technologies such as Earth
observation, navigation, and scientific research. However, achieving
reliable data transmission remains a challenge due to dynamic link
availability, limited bandwidth, and energy constraints in small
satellites. This study proposes an advanced DTN-based architecture
integrated with a deep-space relay network tailored for small satellite
communications. The architecture employs adaptive routing protocols
and priority-based data queuing to ensure optimal resource utilization
and data delivery. Performance evaluations conducted using
simulation models indicate a significant improvement in network
efficiency. Key metrics demonstrate a 25% reduction in data delivery
latency and an 18% increase in successful data transmission rates
compared to conventional methods. Furthermore, energy consumption
is optimized by 15%, making it suitable for small satellites with limited
power resources. These findings underscore the potential of DTN and
deep-space relay networks in revolutionizing small satellite
communication, enabling more reliable and efficient connectivity in
modern technological applications.
