3 Why cognitive? Need to produce decisions in the presence of incomplete, inconsistent, maybe misleading or malicious information conflicting or inconsistent high-level objectives drastically/instantaneously changing operational conditions high complexity, increased number of tunable parameters spatial and temporal dynamics C. Fortuna, M. Mohorcic, “Trends in the development of communication networks: Cognitive networks,” Computer Networks, vol 53, no 9, June 2009, pp

4 Cooperation in Personal Networks

5 Cognitive Control Plane (CCP) Scene analysis: observes the users, devices, networks, spectral resources… Recognizes the parameters, measures, assertions and produces conclusions through explanations Acts: does the reasoning, optimization, adaptation, learning… Evolves continuously…

6 Benefits of CCP reduces the complexity, increases manageability, increases usability, supports application/service portability and compatibility, enhances security/dependability, enables evolutionary advancement of the technologies without impacting the users.

7 Research challenges Context acquisition, what should be sensed and correlated? Knowledge/experience routing among cognitive elements Fault diagnosis and mitigation Support for users/applications beyond suggestions Security and trust relations among cognitive elements Analysis of emergent behavior: conflicts b/w endogenous and exogenous components Autonomic self-* mechanisms Analysis of stigmergy of cognitive elements Distributed/centralized or semi-distributed decision making? Scalability? Policies/rules derivation, to which extend the n/w administrator should be in the loop? Governance model? …

8 Stigmergy – source wikipedia Stigmergy is a mechanism of spontaneous, indirect coordination between agents or actions, where the trace left in the environment by an action stimulates the performance of a subsequent action, by the same or a different agent.coordinationenvironment Stigmergy is a form of self-organization.self-organization It produces complex, apparently intelligent structures, without need for any planning, control, or even communication between the agents. As such it supports efficient collaboration between extremely simple agents, who lack any memory, intelligence or even awareness of each other
