An ad-hoc (or "spontaneous") network is a local area network or other small network, especially one with wireless or temporary plug-in connections, in which some of the network devices are part of the network only for the duration of a communications session or, in the case of mobile or portable devices, while in some close proximity to the rest of the network. The term has been applied to future office or home networks in which new devices can be quickly added, using, for example, Bluetooth technology in which devices communicate with the computer and perhaps other devices using wireless transmission. This book covers the latest research in the field.
