Theo was a student of Chip Maguire who also was advising Joe Mitola, the originator of cognitive radio.
Mitola's Licentiate thesis, published in August, 1999 includes the following quote "Over time, the [Radio Knowledge Representation Language] RKRL-empowered network can learn to distinguish a feature of the natural environment that does not match the models.
In 2004, Petri Mahonen, currently at RWTH, Aachen, and a member of Mitola's doctoral committee organized the first international workshop on cognitive wireless networks at Dagstuhl, Germany.
This loop, the cognition loop, senses the environment, plans actions according to input from sensors and network policies, decides which scenario fits best its end-to-end purpose using a reasoning engine, and finally acts on the chosen scenario as discussed in the previous section.
This definition of CN seems to be incomplete since it lacks knowledge which is an important component of a cognitive system as discussed in,[5][6][7][8] and.
[9] Balamuralidhar and Prasad[8] gives an interesting view of the role of ontological knowledge representation: “The persistent nature of this ontology enables proactiveness and robustness to ‘ignorable events’ while the unitary nature enables end-to-end adaptations.” In,[5] CN is seen as a communication network augmented by a knowledge plane that can span vertically over layers (making use of cross-layer design) and/or horizontally across technologies and nodes (covering a heterogeneous environment).
The peer-to-peer unicast module can deliver data packets from source to destination over multiple wireless hops.
The multicast module sends data packets to multiple destinations, as compared to peer-to-peer unicast.
The data-aggregation module opportunistically collects and aggregates the context related data from a set of proximity wireless nodes.
