What is the primary feature of ad hoc networks?

The primary feature of ad hoc networks is dynamic topology. In an ad hoc network, nodes can join and leave the network freely, which results in a constantly changing network structure. Unlike traditional networks with fixed infrastructures, the lack of a central authority to manage the connections means that each node is responsible for discovering and maintaining routes to other nodes. This flexibility allows the network to adapt to changes quickly, making it suitable for various applications, especially in mobile and temporary environments where network conditions can vary rapidly.

The dynamic nature of ad hoc networks is crucial for their functionality, as it allows for seamless communication among devices without the need for pre-established agreements or configurations. This characteristic is what defines the operational paradigm of ad hoc networks, emphasizing adaptability and decentralized management in contrast to more rigid network structures.
