Ad Hoc Network Protocols are communication protocols designed for temporary networks formed by devices without a fixed infrastructure. These networks allow devices to connect directly to each other, enabling data exchange in situations where traditional networks are unavailable or impractical, such as in disaster recovery or military operations. These protocols facilitate dynamic routing and data transmission among devices, adapting to changes in network topology. Examples include Ad hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR), which help maintain efficient communication as devices join or leave the network, ensuring reliable connectivity in a flexible environment.
