摘要：In recent years, the technological improvement in wireless communication and mobile computing stimulated a consistent growth both in number and types of implementations for wireless networks. Minimizing power consumption thus improving power efficiency can significantly extend the wireless devices battery longevity and its serviceability. A node must learn neighbourhood nodes that are in direct communication range, before it initiates communication. The gathered relevant information is kept in its internal data structures to apply with routing. The wireless ad-hoc nodes acclimatize dynamically its topology knowledge range, leading to faster convergence of its neighbouring nodes. The intention of topology control is to restrict communication deliberately and use multi-hop paths instead of direct communication links between nodes, even if they are within the communication range of each other. Thus, connectivity or fault-tolerance is preserved while reducing transmission power, improving network capacity, better SNR and also enhanced spatial reuse. In this paper, we present an overview of a range of centralized and distributed topology control algorithms. We also provide an extensive comparison of these algorithms and suggest the metrics to refine future topology control algorithms.
