What is a mesh network in wireless communication?

A mesh network in wireless communication is characterized by its topology that involves nodes relaying data to one another, creating multiple pathways for data transmission. This interconnected structure allows each device, or node, to communicate directly with one another, rather than relying on a central hub or router. The significant advantage of this design is its resilience; if one node fails, data can find alternative routes through other nodes, which enhances reliability and coverage.

In a mesh network, the nodes can dynamically work together to optimize routing and communication, using algorithms to determine the best path for data to travel. This capability is particularly beneficial in scenarios where connectivity is essential, such as in smart homes or large-scale network deployments, where seamless communication among devices is crucial.

Other network types, such as linear or centralized configurations, do not offer the same flexibility and robustness, as they often rely on a single point of control or have limited connectivity options. Additionally, disconnected series of nodes do not provide the redundancy or the multi-path advantages inherent in a mesh structure. Thus, option C distinctly captures the essence of a mesh network, reflecting its ability to utilize multiple relaying nodes for efficient and reliable communication.
