What are temporary wireless networks without a central access point called?

Temporary wireless networks that operate without a central access point are known as ad hoc networks. This type of network allows devices to communicate directly with one another, forming a dynamic connection among peers without the need for traditional networking infrastructure like routers or access points.

Ad hoc networks are particularly useful in scenarios where conventional networking is impractical, such as in emergency situations, temporary events, or when setting up a quick connection in remote areas. The direct peer-to-peer communication facilitates quick setup and flexibility, as nodes in an ad hoc network can join or leave the network at will, adapting to changing conditions and requirements.

The other types of networks mentioned do have specific characteristics that differentiate them from ad hoc networks. For example, point-to-point networks typically involve a dedicated connection between two network devices. Mesh networks utilize multiple connections between devices to strengthen and provide redundancy to the overall network structure, ensuring reliable communication. Infrastructure networks are characterized by the presence of central access points, which manage connections and direct traffic, contrasting with the decentralized nature of ad hoc networks.
