Cognitive Networks: Towards Self-Aware Networks

8.2. Towards Ad Hoc Networks

Many networking systems, algorithms and techniques lay claim to the notion of having ad hoc attributes or employing ad hoc techniques, and through such labeling these systems impute that they are somehow more capable, more flexible and more prepared for dynamic communications challenges than competing systems and standards. But a networking system that can truly call itself ad hoc should be more than a network which allows plug-and-play master/slave connectivity, such as that provided by Bluetooth ^[], or which allows peer-to-peer network formation such as that enabled by the IEEE 802.11 MAC ^[]. Within these standards the scope for quasi-ad hoc behavior is tightly constrained. So, before we even begin to discuss cognitive ad hoc networks, we take a fresh look at what it means to be simply ad hoc.

Returning to basics, the Latin phrase ad hoc, translates literally to the English phrase to this. In contemporary usage, it is often used as an adjective, meaning for this purpose; to this end; for the particular purpose in hand or in view. One of the more familiar usages of the phrase is in the context of institutional ad hoc committees. Such committees are generally established by parliaments, unions, corporations and other bodies on a temporary basis to address unforeseen issues and events, to serve as forums for debate and decision making and to allow their institutions to respond to new or changed circumstances. Such ad hoc committees are required when ...
