The initial vision of the Internet Things was a world in which all physical objects are tagged and uniquely identified by RFID transponders. However, concept has grown into multiple dimensions, encompassing sensor networks able to provide real-world intelligence goal-oriented collaboration distributed smart via local or global interconnections such as Internet. Despite significant technological advances, difficulties associated with evaluation IoT solutions under realistic conditions...

Abstract Smart city represents one of the most promising, prominent and challenging Internet Things (IoT) applications [1]. In last few years, indeed, smart concept has played an important role in academic industry fields, with development deployment various middleware platforms IoT‐based infrastructures. However, this expansion followed distinct approaches creating, therefore, a fragmented scenario, which different IoT ecosystems are not able to communicate between them. To fill gap, there...

Abstract In the current worldwide ICT scenario, a constantly growing number of ever more powerful devices (smartphones, sensors, household appliances, RFID devices, etc.) join Internet, significantly impacting global traffic volume (data sharing, voice, multimedia, and foreshadowing world (more or less) smart “things” in Internet Things (IoT) perspective. Heterogeneous resources can be aggregated abstracted according to tailored thing-like semantics, thus enabling as Service paradigm, better...

In last few years, smart city concept has played an important role in academic industry fields, with development deployment various middleware platforms. However, this expansion followed distinct approaches creating a fragmented scenario, which different IoT ecosystems are not able to communicate between them.

Wireless networks are now a part of the everyday life many people and used for applications. Recently, new technologies that enable low-power long-range communications have emerged. These technologies, in opposition to more traditional communication rather defined as "short range", allow kilometer-wide wireless communications. Long-range form Low-Power Wide-Area Networks (LPWAN). Many LPWAN available, they offer different performances, business models etc., answering applications’ needs....

Named Data Networking (NDN) is a promising paradigm for the future Internet architecture that also opens new perspectives in way data can be retrieved Wireless Sensor Networks (WSNs). In this paper, we explore potentialities of NDN applied to WSNs and propose enhancements forwarding strategy by including principles inspired traditional data-centric routing schemes. Results achieved through ndnSIM simulator confirm viability effectiveness proposal.

This paper analyzes the information delivery delay for purpose of roadside unit (RSU) deployment in a vehicular ad hoc network (VANET) with intermittent connectivity. A mathematical model is developed to describe relationship between average delivering road condition and distance two neighbor RSUs. The derived considers sparse highway scenario where RSUs are deployed at without direct connection, vehicles sparsely distributed on randomly generated Moreover, takes into account vehicle speed,...

Molecular Communication (MC) is an emerging and promising communication paradigm for several multi-disciplinary domains like bio-medical, industry military. Differently to the traditional paradigm, information encoded on molecules, that are then used as carriers of information. Novel approaches related this new have been proposed, mainly focusing architectural aspects categorization potential applications. So far, security privacy molecular systems not investigated at all represent open...

When a natural or human disaster occurs, time is critical and often of vital importance. Data from the incident area containing information to guide search rescue (SAR) operations improve intervention effectiveness should be collected as quickly possible with highest accuracy possible. Nowadays, rescuers are assisted by different robots able fly, climb crawl, sensors wireless communication means. However, heterogeneity devices data together strong low-delay requirements cause these...

In mobile-beacon assisted sensor localization, beacon mobility scheduling aims to determine the best trajectory so that each receives sufficient signals and becomes localized with minimum delay. We propose a novel DeteRministic dynamic bEAcon Mobility Scheduling (DREAMS) algorithm, without requiring any prior knowledge of sensory field. this is defined as track Depth-First Traversal (DFT) network graph, thus deterministic. The mobile performs DFT dynamically, under instruction nearby sensors...

The Internet of Things (IoT) will enable objects to become active participants everyday activities. Introducing into the control processes complex systems makes IoT security very difficult address. Indeed, is a paradigm in which people interact with technological ecosystem based on smart through processes. interactions these four components, person, intelligent object, ecosystem, and process, highlight systemic cognitive dimension within IoT. interaction requires protection their privacy....

This paper studies the RSU deployment problem in a 2-D urban or suburban road scenario of vehicular ad hoc network (VANET). To optimize deployment, we introduce notion centrality social to and use it measure importance an position candidate deployment. Based on centrality, propose centrality-based approach formulate as linear programming with objective maximize total all candidates selected for under constraint given budget. solve formulated problem, analogize 0-1 Knapsack thus employ...

The Smart Grid (SG) aims to transform the current electric grid into a "smarter" network where integration of renewable energy resources, efficiency and fault tolerance are main benefits. This is done by interconnecting every source, storage point or central control with connected devices, heterogeneous SG applications signalling messages will have different requirements in terms reliability, latency priority. Hence, data routing prioritization challenges such networks. So far, RPL (Routing...

With the development of new technologies, these last years have witnessed emergence a paradigm: Internet Things (IoT) and physical world. We are now able to communicate interact with our surrounding environment through use multiple tiny sensors, RFID technologies or small wireless robots. This allows set applications usages be envisioned ranging from logistic traceability purposes emergency rescue operations going monitoring volcanos forest fires.
