An ad hoc network refers to a temporary or spontaneous wireless network that is formed by a group of devices for communication purposes. This type of network is created on the fly, without the need for any pre-existing infrastructure or centralized authority. Ad hoc networks are typically deployed in situations where conventional networks are inaccessible, unreliable, or impractical to establish.
In an ad hoc network, several devices, such as laptops, smartphones, or IoT devices, come together to form a network for sharing data and resources. These devices collaborate to establish communication links without relying on a fixed infrastructure or dedicated access points. The network can be established through various wireless technologies, such as Wi-Fi, Bluetooth, or mobile ad hoc networking (MANET) protocols.
The formation of an ad hoc network can be initiated by a single device or through cooperative efforts between multiple devices. The devices dynamically discover and connect to each other, allowing communication to occur. Ad hoc networks are capable of self-configuring, self-healing, and self-organizing, adapting to changes in network topology and adding or removing devices as needed.
Ad hoc networks find utility in various scenarios, including disaster-stricken areas, military operations, conferences, or even social gatherings. These networks enable quick and flexible communication among devices within their range, without depending on a fixed infrastructure. However, due to their decentralized nature, ad hoc networks may have limitations in terms of scalability, security, and reliable connectivity over longer distances.
