Control channels for the cooperation of cognitive management systems in opportunistic and composite wireless networks

Opportunistic Networks (ONs) are assumed to be temporary, localized extensions of the infrastructure network that are created under certain circumstances. According to that vision, ONs are coordinated by the radio access network (RAN) operator which governs the overal system behaviour (e.g. ON related policies), provides the neccessary resources (e.g. dedicated specturm bands) and supports users in decision making (e.g. additional knowledge and context information). ONs comprise both nodes of the infrastructure and infrastructure-less devices. For the management and control of operator-governed ONs the introduction of Cognitive Management Systems (CMSs), localized on the terminal and infrastructure side, is proposed. The cooperation of CMS entities will require existence of well-defined control channels. In order to enable the necessary signalling between the CMS entities, Control Channels for the Cooperation of the Cognitive Management Systems (C4 MS) are proposed.Peer ReviewedPostprint (published version

Cognitive control channels for the cooperation of opportunistic and composite wireless networks

Opportunistic networks (ONs) are considered as coordinated extensions of a radio access network infrastructure, which are dynamically and temporarily created in an infrastructure-less manner in order to increase service reachability, improve resource utilization efficiency and facilitate localised service provisioning. The realization of the ON concept relies on the existence of control channels which will provide necessary signalling for the coordination of the ON nodes. Proposed control channels are conceived as an evolution of the already established cognitive pilot channel concept. As a result, new interfaces are discussed in order to convey information from the infrastructure to the terminals and vice versa or between terminals. Finally, the business benefits of the aforementioned approach are provided in order to strengthen the notion of the proposed control channels and consider future expansions.Peer ReviewedPostprint (published version

A CORRELATION STUDY OF MAJOR AND TRACE ELEMENTS IN SEDIMENTS OF RIVER NESTOS, NORTHERN GREECE AND COMPARISON WITH OTHER FLUVIAL SYSTEMS

ABSTRACT Fourteen sediment samples from the banks of River Nestos, Northern Greece, were collected, extracted with HNO 3 and analyzed for their content in 10 major and 32 trace elements. The analytical techniques used were ICP-OES and ICP-MS. The calculation of the Pearson Correlation Coefficient amongst the analyzed elements has revealed that among the majority of the elements exist positive correlations, which explains why most of them have a similar distribution along the river course. A comparison between the results acquired for the River Nestos and other fluvial systems, national and international, has shown the similarity of the geochemical identity of the River Nestos sediments with these systems

Protocols, performance assessment and consolidation on interfaces for standardization – D3.3

The following document presents a detailed description of the protocol for the “ Control Channels for the Cooperation of the Cognitive Management System ” (C4MS) which provides the necessary means to enable proper management of Opportunistic Networks. Additionally, the document defines the methodology that was applied for the purpose of signalling evaluation. The protocol overview presented in section 2 of the main document, provides the C4MS principles. The section includes, among others, the description of the protocol identifiers, procedures, protocol state machines and message format as well as the security asp ects. Section 3 provides a high-level description of the data structures defined within the scope of OneFIT project. The data structures are classified into five categories, i.e.: Profiles, Context, Decisions,Knowledge and Policies. The high level description is complemented by some detailed data structures in the Appendix to D3.3 Section 3[10]. Section 4 provides details on the evaluation methodology applied for the purpose of C4MS performance assessment. The section presents the evaluation plan along with a description of metrics that are to be exploited in the scope of WP3. Section 5 and Section 6 are composed of the signalling evaluation results. Section 5 focuses on the estimation of the signalling load imposed by ON management in different ON phases. Additionally some results for the initialization phase (not explicitly mentioned in the previous phases of the project)and security related aspects are also depicted. Section 6 on the other hand is focused on the evaluation of the signalling traffic generated by different ON related algorithms. Conclusions to the document are drawn in section 7. Detailed description of the C4MS procedures, implementation options based on IEEE 802.21, DIAMTER and 3GPP are depicted in the appendix to the D3.3[10] . Additionally, the appendix incorporates the detailed definition of the information data structures and final set of Message Sequence Charts (MSCs) provided for the OneFIT project.Peer ReviewedPreprin
