“…(10)- (12) impose that, if a GW is powered off, no UT or GW can be connected to it, Eq. (13) impose that no content can be retrieved from a powered-off GW, and finally Eqs. (14) and (15) are the classical capacity constraints (one for each wireless interface of the GW -we assume that the wired link to the Internet has unlimited bandwidth).…”

“…Also, since many works on content caching already exist, we do not deal with content placement on the GWs, but take it for granted that a suitable CDN strategy has been enforced (see e.g. [7,10,12,13]). Therefore our work does not integrate the definition of a CDN approach, but is complementary to it.…”

The Internet of Things (IoT) makes our lives much easier, more valuable, and less stressful due to the development of many applications around us including smart cities, smart cars, and smart grids, offering endless services and solutions. Protecting IoT data of such applications at rest either on the objects or in the cloud is an indispensable requirement for achieving a symmetry in the handling and protection of the IoT, as we do with data created by persons and applications. This is because unauthorised access to such data may lead to harmful consequences such as linkage attacks, loss of privacy, and data manipulation. Such undesired implications may jeopardise the existence of IoT applications if protection measures are not taken, and they stem from two main factors. One is that IoT objects have limited capabilities in terms of memory capacity, battery life, and computational power that hamper the direct implementation of conventional Internet security solutions without some modifications (e.g., traditional symmetric algorithms). Another factor is the absence of widely accepted IoT security and privacy guidelines for IoT data at rest and their appropriate countermeasures, which would help IoT stakeholders (e.g., developers, manufacturers) to develop secure IoT systems and therefore enhance IoT security and privacy by design. Toward this end, we first briefly describe the main IoT security goals and identify IoT stakeholders. Moreover, we briefly discuss the most well-known data protection frameworks (e.g., General Data Protection Regulation (GDPR), Health Insurance Portability (HIPAA)). Second, we highlight potential attacks and threats against data at rest and show their violated security goals (e.g., confidentiality and integrity). Third, we review a list of protection measures by which our proposed guidelines can be accomplished. Fourth, we propose a framework of security and privacy guidelines for IoT data at rest that can be utilised to enhance IoT security and privacy by design and establish a symmetry with the protection of user-created data. Our framework also presents the link between the suggested guidelines, mitigation techniques, and attacks. Moreover, we state those IoT stakeholders (e.g., manufacturers, developers) who will benefit most from these guidelines. Finally, we suggest several open issues requiring further investigation in the future, and we also discuss the limitations of our suggested framework.

“…Similarly, our analysis starts from a given content placement pattern, laid out by a suitable CDN approach (see e.g. ). Therefore, our work does not integrate the placement of the contents but is complementary to the CDN deployment.…”

In this paper, we study a wireless access network based on the Institute of Electrical and Electronics Engineers 802.11 standard and enriched with features such as caching and mesh networking. This system is analysed in terms of energy efficiency and traffic offloading, two objectives that are somewhat in contrast but both relevant to network and service providers as they directly impact the operational cost. In addition, QoS is also accounted for in the form of guaranteed bandwidth and bounded delay. To this aim, we developed a mathematical model of the system and solved it to optimality by means of integer linear programming. We can thus show how much can be saved both in terms of energy and traffic, also considering various tradeoff points among the two contrasting objectives. As a last step, we provide an investigation on the benefits of adding traffic aggregation features to the mathematical model
