Satellite mesh constellations are rapidly expanding globally, promising ubiquitous connectivity, and bridging the digital divide. Advances in satellite technology have facilitated the deployment of large, interconnected constellations such as Starlink, project Kuiper, and OneWeb Networks. Direct communication among satellites via Inter-Satellite Links (ISLs) within a mesh network topology is pivotal for reducing reliance on ground infrastructures. ISLs, enabled by optical or RF-based terminals, empower real-time applications by minimizing the need for ground station relaying. However, managing the complex interplay of numerous satellites in a large constellation demands sophisticated network management. Efficient resource allocation, routing protocols, and optimization techniques become imperative. Centralized and decentralized algorithms are proposed to address this challenge. Limited power and computing resources on satellites necessitate the design of communication protocols and algorithms that optimize resource usage and minimize energy consumption. This paper reviews challenges associated with satellite mesh constellations and studies solutions to ensure the successful operation and optimization of these Mega Constellation Networks (MCN). Key areas of focus include ISLs, resource allocation, and the design of communication protocols. Addressing these challenges is vital for realizing the full potential of satellite constellations in connecting the global population.
