Recent years have witnessed a significant surge of interest in the design and development of local algorithms for solving various network tasks, particularly due to their critical importance in the study and application of wireless networks. These local algorithms, characterized by their reliance on limited and localized information, are essential for ensuring efficient and scalable network operations. In this work, we specifically focus on the behavior and performance of algorithms operating under very low locality constraints, where each node has access to minimal information about its immediate neighborhood. Despite the inherent limitations imposed by such restricted locality, we successfully propose local constant-ratio approximation algorithms for solving several fundamental problems in location-aware Unit Disk Graphs (UDGs). These problems include the Minimum Dominating Set (MDS), Connected Dominating Set (CDS), Maximum Independent Set (MIS), and Minimum Vertex Cover (MVC). The proposed algorithms demonstrate that even with constrained locality, it is possible to achieve effective approximations for these challenging combinatorial problems in the context of wireless networks. Furthermore, this study contributes to the theoretical understanding of local algorithms by establishing the first-ever lower bounds on their performance for the aforementioned problems within a location-aware UDG setting. These bounds provide valuable insights into the trade-offs between locality and the achievable solution quality, offering a deeper understanding of the limitations and potential of local algorithms in practical scenarios. By addressing both algorithmic solutions and theoretical limits, this work not only advances the state of the art in local algorithm design for wireless networks but also lays a foundation for future research aimed at further exploring and optimizing locality-aware approaches in distributed systems.
