The advent of 6G networks and beyond calls for innovative paradigms to address the stringent demands emerging applications, such as extended reality autonomous vehicles, well technological frameworks like digital twin networks. Traditional cloud computing edge architectures fall short in providing their required flexibility, scalability, ultra-low latency. Cloud centralizes resources distant data centers, leading high latency increased network congestion, while computing, though closer sources, lacks agility dynamically adapt fluctuating workloads, user mobility, real-time requirements. In-network (INC) offers a transformative solution by integrating computational capabilities directly into fabric, enabling dynamic distributed task execution. This paper explores INC through lens information-centric networking (ICN), revolutionary communication paradigm implementing routing-by-name in-network caching, thus natural enabler INC. We review state-of-the-art advancements involving ICN, addressing critical topics service naming, executor selection strategies, compute reuse, security. Furthermore, we discuss key challenges propose research directions deploying via thereby outlining cohesive roadmap future investigation.

Sixth-generation (6G) wireless networks have the potential to transform global connectivity by supporting ultra-high data rates, ultra-reliable low latency communication (uRLLC), and intelligent, adaptive networking. To realize this vision, 6G must incorporate groundbreaking technologies that enhance network efficiency, spectral utilization, dynamic adaptability. Among them, unmanned aerial vehicles (UAVs), terahertz (THz) communication, intelligent reconfigurable surfaces (IRSs) are three major enablers in redefining architecture performance of next-generation systems. This survey provides a comprehensive review these transformative technologies, exploring their potential, design challenges, integration into future ecosystems. UAV-based flexible, on-demand remote, harsh areas is vital solution for disasters, self-driving, industrial automation.
