Internet of Things (IoT) comprises of large number of devices which are heterogeneous in their hardware potentials and types of data traffic. In addition, IoT network is not having a common QoS (Quality of Service) goal but exhibits heterogeneous QoS demands which are dynamically driven by different IoT services such as smart city, e-health, e-business, smart parking etc. These heterogeneous services result in sporadic spectrum usage and make it difficult to achieve spectrum efficiency in IoT. It will also lead to spectrum scarcity for emergency IoT services. In this paper, Multi Criteria Decision Making (MCDM) approach is proposed to coordinate IoT devices in spectrum sharing. This frame work evaluates and ranks the available spectrum bands based on their multiple spectral characteristics to match with the capacities and QoS needs of IoT devices. The complexity of the traditional multiple criteria ranking is reduced by one-fourth by introducing a Service-based Analytical Hierarchical Processing (S-AHP). Proposed framework is realized with fogcomputing-MapReduce infrastructure to meet the latency constraints of IoT devices. Hadoop based simulation results show that the proposed approach achieves improved spectrum utilization and reduced service drops in comparison with other MCDM approaches such as Simple Additive Weighting (SAW) and Preference Selection Index (PSI).

In the three hierarchy architecture Edge-fog-Cloud, delivering services with low latency is needed from the cloud to fog users with the intermediate of fog servers. Private and secure communication scheme will be necessary between fog users and dynamic fog servers. fog servers are dynamic in joining and leaving the fog. This dynamic change of fogs must be transparent to the fog users. Our solution lies on the introduction of a mutual authentication between fog users at the Edge of the network and the fog servers at the fog layer. We propose a fog user-fog server anonymous mutual authentication scheme in which fog user and fog server authenticate each other and establish a session key without disclosing user's real identity. Our scheme is based on Pseudonym Based Cryptography PBC, Elliptic Curve Discrete Logarithm Problem ECDLP and bilinear pairing to establish the session key. To evaluate the new solution, a security analysis and a formal validation with AVISPA are presented.

Due to the emergence of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) paradigms, coupled with a hyper-connectivity communication paradigm, the "softwarization" of the Internet infrastructure and of its network management framework is gaining increasing popularity. This is the target of the INPUT platform, a novel infrastructure and paradigm supporting Future Internet personal cloud services in a more scalable and sustainable way, and with innovative added-value capabilities. The INPUT technologies enable nextgeneration cloud applications to go beyond classical service models, and even replace physical Smart Devices, usually placed in users' homes (e.g., set-top boxes), with their virtual images, providing them to users "as a Service". In this paper we present the Virtual set-top box from both architectural and functional points of view, demonstrating the feasibility of the softwarized SDN/NFV paradigm joined with the fog-computing approach to support personal cloud services.(1)
