Working Group 2

Topic: Definition of cooperation-based cognitive algorithms, that take advantage of information exchange at a local level

Technical information

WG2 will focus on the definition of cognitive mechanisms taking advantage of cooperation of devices in spatial proximity, according to the research issues identified as part of Technical Challenge 2 (TC2). More in detail, TC2 deals with the definition of cooperation-based cognitive algorithms, that take advantage of information exchange at a local level. Operational requirements imposed on cognitive radios may occasionally exceed the capabilities of a single device; in such cases cooperation at a local level among neighbouring devices can lead to significant performance enhancements. Examples of research topics relevant to TC2 are:

o Design of cooperative spectrum sensing algorithms, where groups of cognitive devices exchange information in order to increase reliability and accuracy in spectrum sensing, probability of detection of alien wireless systems, and classification of features of radio emissions;

o Design of cooperative relaying schemes, in order to efficiently address limitations in coverage and network connectivity due to emission limits imposed on secondary cognitive radio devices;

o Design of advanced network coding schemes, aiming at optimal use of available power based on node cooperation towards throughput maximization, while meeting coexistence requirements;

o Definition of an efficient representation language for information exchange between cooperating nodes.
