In a world of pervasive computing, embedded systems can be found in a wide range of products and are employed in various heterogeneous domains. The abovementioned devices often need to access, store, manipulate and/or communicate sensitive or even critical information, making the security of their resources and services an important concern in their design process. These issues are further exacerbated by the resource-constrained nature of the devices, in conjunction with the ever-present need for smaller size and lower production costs. This paper aims to provide an overview of the challenges in designing secure embedded systems, covering both node hardware and software issues, as well as relevant network protocols and cryptographic algorithms. Moreover, recent advances in the field are identified, highlighting opportunities for future research.

This paper addresses the importance of continuously evaluating an organization's awareness program and provides guidelines that will help organizations assess their efforts, extending the authors' work in [1]. The proposed methodology evaluates an awareness program considering the most common and essential methods used for delivering awareness material. Key awareness-related processes and accompanying quantitative metrics are identified, along with a methodology for dynamically evaluating the metrics and the overall awareness program as a whole. A software tool is developed, to facilitate the deployment and maintenance of the assessment methods and to formalize their aggregation and evaluation. An organization's security awareness posture is modelled as a dynamic system and the awareness level is calculated and monitored through time via Event Calculus. Furthermore, the tool can be deployed in a multi-agent form, to enable its use by organizations operating through remote offices and distributed locations. © 2014 Springer International Publishing.

Mobile Ad hoc NETworks (MANETs) are becoming more essential to wireless communications due to growing popularity of mobile devices. However, MANETs do not seem to effectively support multimedia applications and especially video transmission. In this work, we propose a cross-layer design that aims to improve the performance of video transmission using TCP Friendly Rate Control (TFRC). Our design provides priority to video packets and exploits information from the MAC layer in order to improve TFRC's performance. The proposed cross-layer design utilizes SNR measurements along the routing path, in order to make the route reconstruction procedure more efficient. Simulation results show that both the use of traffic classification and the SNR utilization lead to important improvements in terms of end-to-end Quality of Service (QoS). © 2014 Academy Publisher.

The demand-side energy management of microgrids comprising of buildings of heterogeneous nature (residential, commercial, industrial, etc.) and thus exhibiting heterogeneous occupancy pattern, requires the development of appropriate energy management systems (EMSs) that can integrate the maximum exploitation of the distributed energy resources like photovoltaic panels with the thermal comfort of the occupants. This paper presents a simulation-based optimization approach for the design of an EMS in grid-connected photovoltaic-equipped microgrids with heterogeneous buildings and occupancy schedules. The EMS optimizes a multi-objective criterion that takes into account both the energy cost and the thermal comfort of the aggregate microgrid. A three-building microgrid test case is used to demonstrate the effectiveness of the proposed approach: comparisons with alternative rule-based and optimization-based EMSs show that the proposed EMS strategy exploits the occupancy information to automatically change the energy demand of each building, resulting in improved energy cost and thermal comfort.

Broadband is starting to be deemed by many as a public utility and several countries have already recognized it as a civil right. The European Commission (EC) acknowledging the significance of broadband services for the improvement of citizen welfare and its economic benefits, has put in place targets for the diffusion of broadband to all citizens and businesses in the European Union. This paper, comparatively assesses the current state of affairs in broadband and digital public services in selected South East Europe countries in order to identify weaknesses and highlight strengths and to produce knowledge resources and provide insights that will support informed decision making including strategy and policy planning. It builds on three surveys that took place in the second quarter of 2013 and evidence gathered from seven South East Europe countries. © 2014 IEEE.

Over the recent past years research effort has been dedicated towards addressing a generic solution in System of Systems (SoS) control problems. Two are the main obstacles that have to be bypassed in such problem cases, especially in real life applications, rendering the optimization problem into a complicated/challenging one: (i) modelling/simulation tools are usually used in order to construct an as-close-as-possible to reality accurate model, whose construction though requires a considerable amount of time and effort and (ii) furthermore, standard control system designs when applied to SoS exhibit poor performance as they are required to handle very high-dimensional problems. In this paper, we present a first attempt towards addressing these issues. More precisely, a new adaptive optimal control methodology is presented and evaluated. The main attributes of the proposed control methodology is its local nature with minimum requirements for coordination between the constituent system of the SoS and its model-free nature.

A method aimed at refinement of the cyclic steady state space reachable in the given multimodal transportation network is proposed. The paper introduces the concept of a System of Concurrent Multimodal Cyclic Processes in which several subnetworks interact each other via distinguished subsets of common shared workstations as to provide a variety of demandresponsive work-piece transportation/handling services. Searching for the cyclic steady state behavior the following question is considered: Is the cyclic steady state space reachable in the given network structure ? The declarative approach employed makes it possible to evaluate the reachability of cyclic behaviors on a scale that reflects real practice. © Springer International Publishing Switzerland 2014.

The problem of cyclic scheduling of multimodal concurrent processes (MCPs) is considered. Processes composed of sub-sequences of local cyclic processes (LCPs) are treated as multimodal processes, e.g. in case local processes encompass the subway lines network the relevant multimodal processes can be seen as passengers traveling itineraries this network. Since LCPs network implies a MCPs behavior, the following fundamental questions arise: Does the given LCPs network guarantee an assumed cyclic schedule of the MCPs at hand? Does there exist the LCPs network such that an assumed cyclic schedule of MCPs can be achieved? In that context our contribution is to propose a declarative framework allowing one to take into account both direct and reverse problems formulation. © Springer International Publishing Switzerland 2014.

In this paper, we propose the example-specific density based matching kernel (ESDMK) for classification of scene images represented as sets of local feature vectors. The proposed kernel is computed between the pair of examples, represented as sets of local feature vectors, by matching the estimates of example-specific densities computed at every local feature vector in those two examples. In this work, the number of local feature vectors of an example among the K nearest neighbors of a local feature vector is considered as an estimate of the example-specific density. The minimum of the two example-specific densities, one for each example, at a local feature vector is considered as the matching score. The ESDMK is then computed as the sum of the matching score computed at every local feature vector in a pair of examples. We also propose the spatial ESDMK (SESDMK) to include spatial information present in the scene images while matching the pair of scene images. Each of the scene images is divided spatially into a fixed number of regions. Then the SESDMK is computed as a combination of region specific ESDMKs that match the corresponding regions. We study the performance of the support vector machine (SVM) based classifiers using the proposed ESDMKs for scene classification and compare with that of the SVM-based classifiers using the state-of-the-art kernels for sets of local feature vectors.
