There are new and important advancements in today’s complexity theories in ICT and requires an extraordinary perspective on the interaction between living systems and information technologies. With human evolution and its continuous link with the development of new tools and environmental changes...

With the developments and intersection of science and engineering, cognitive informatics has emerged as a new and intriguing field of study which investigates the natural intelligence and internal information processing mechanisms of the brain as well as the methods involved in perception and...

Cognitive networks can be crucial for the evolution of future communication systems; however, current trends have indicated major movement in other relevant fields towards the integration of different techniques for the realization of self-aware and self-adaptive communication systems. Evolution of...

Since the first production of tools at the beginning of human presence on earth, evolutionary jumps mark human development. Sometimes, these punctuations were triggered by inventions of new tools, combined with new environmental adaptations. Affordances, as specialized forms of symbiotic embodiment...

In this chapter, the authors examine some similarities between computer science and psychoanalysis, and formulate some hypotheses by bringing closer the statute of connectionism to the energetic model of the psychic apparatus as well as the OOP (object-oriented programming) to the object relations...

Fast development of computer networking contributes to the global spreading and popularizing of the notion of fractals and complex patterns in their use in computer-aided design and computer art. This chapter looks for answers to the following questions: How are fractals perceived? Are fractals...

Inference as the basic mechanism of thought is one of the gifted abilities of human beings. It is recognized that a coherent theory and mathematical means are needed for dealing with formal causal inferences. This paper presents a novel denotational mathematical means for formal inferences known as...

In spite of their striking diversity, numerous tasks and architectures of intelligent systems such as those permeating multivariable data analysis, decision-making processes along with their underlying models, recommender systems and others exhibit two evident commonalities. They promote (a) human...

Dealing with the large-scale text knowledge on the Web has become increasingly important with the development of the Web, yet it confronts with several challenges, one of which is to find out as much semantics as possible to represent text knowledge. As the text semantic mining process is also the...

The main topics covered in this paper address the following four issues: (1) Distinction between how adaptation and cognition are viewed with respect to each other, (2) With human cognition viewed as the framework for cognition, the following cognitive processes are identified: the perception-action...

This paper proposes a novel image block encryption algorithm based on three-dimensional Chen chaotic dynamical system. The algorithm works on 32-bit image blocks with a 192-bit secret key. The idea is that the key is employed to drive the Chen’s system to generate a chaotic sequence that is inputted to...

Cooperative networking is considered one of the main enablers for achieving enhanced data rates in wireless communications. This is due to the fact that through cooperation the adverse effects of fading can be alleviated significantly. Thus, more reliable communication systems deployments can be...

In this chapter, the authors provide a comprehensive review of broadcasting and channel selection strategies for wireless cognitive radio networks. In the beginning, some applications of the data dissemination in wireless cognitive radio networks are discussed to highlight their importance and utility....

In this chapter, Joint Radio Resource Management (JRRM) issues in cognitive networks are discussed presenting the TV White Spaces (TVWS) spectrum exploitation use case. TVWS are portions of UHF spectrum, which will be released and interleaved according to the geographical region due to the gradual...

The rapid growth of spectral resources’ demands, as well as the increasing Quality of Service (QoS) requirements of wireless users have led to the necessity for new resource allocation schemes which will take into account the differentiated QoS needs of each wireless user. Towards this direction, the...

Spectrum scarcity has motivated researchers and standardization bodies to work towards flexible spectrum usage. One of the solutions, Spectrum Aggregation, as proposed by 3GPP, is a way to increase wireless capacity through providing additional bandwidth to users. This chapter presents the Spectrum...

Cognitive Radio holds an interesting promise for improved utilisation of the radio spectrum. However, there is a considerable degree of uncertainty regarding the potential application of cognitive radio. One of the reasons for this uncertainty is the need for changes in the regulatory regime to allow...

The problem of spectrum scarcity in uncoordinated and/or heterogeneous wireless networks is the key aspect driving the research in the field of flexible management of frequency resources. In particular, distributed Dynamic Spectrum Access (DSA) algorithms enable an efficient sharing of the available...

The chapter addresses the potential impact of technologies like Autonomic, Cognitive, and Software Defined Networking on future networks evolution. It is argued that said technologies, coupled with a wide adoption of virtualization, will bring an impactful disruption at the edge of current networks: in...

Wireless Mesh Networks (WMNs) are communications networks made up of radio nodes organized in a mesh topology. As a direct evolution from WMNs, the Cognitive Radio Networks (CRN) are similar to the WMNs in many ways. Correspondingly, CRNs are also expected to support delay sensitive and/or high...

Transmission Control Protocol (TCP) is the most commonly used transport protocol on the Internet. All indications assure that it will be an integral part of the future Internetworks. In this chapter, the authors present how regular TCP, which was designed for wired networks, is not suitable for dynamic...

In the current landscape of Mobile Communication Networks, evolved radio access technologies, such as Long Term Evolution (LTE), offer higher bitrates to mobile end users, providing support for a range of resource-demanding applications. In this context, one can imagine that the full potential of the...
