PhyNetLab: An IoT-Based Warehouse Testbed
Future warehouses will be made of modular embedded entities with
communication ability and energy aware operation attached to the traditional
materials handling and warehousing objects. This advancement is mainly to
fulfill the flexibility and scalability needs of the emerging warehouses.
However, it leads to a new layer of complexity during development and
evaluation of such systems due to the multidisciplinarity in logistics,
embedded systems, and wireless communications. Although each discipline
provides theoretical approaches and simulations for these tasks, many issues
are often discovered in a real deployment of the full system. In this paper we
introduce PhyNetLab as a real scale warehouse testbed made of cyber physical
objects (PhyNodes) developed for this type of application. The presented
platform provides a possibility to check the industrial requirement of an
IoT-based warehouse in addition to the typical wireless sensor networks tests.
We describe the hardware and software components of the nodes in addition to
the overall structure of the testbed. Finally, we will demonstrate the
advantages of the testbed by evaluating the performance of the ETSI compliant
radio channel access procedure for an IoT warehouse
Messiah: An ITS drive safety application
This article describes a novel safety application based on the open source navigation software OsmAnd,
which runs on the Android platform. The application offers vehicles with "smart navigation", and maintains a network
of the vehicles that use our application. The process of network creation and maintenance is important as
our application enables vehicles to communicate with one another to exchange useful information. The main
function of the application is to inform vehicles of relevant vehicles approaching, termed as "administrative
vehicles" in this article, and include ambulances, police cars and fire brigades. Based on the received
information, our application notifies the driver, who can now take navigation decisions based on it. While developing
the application, problems were found when attempting to create an Ad-hoc network. A solution to the problem of managing the Ad-hoc network has been proposed and is under development

Cooperative Vehicular Platooning (Co-VP) is a paradigmatic example of a Cooperative Cyber-Physical System (Co-CPS), which holds the potential to vastly improve
road safety by partially removing humans from the driving task. However, the challenges are substantial, as the domain involves several topics, such as control theory,
communications, vehicle dynamics, security, and traffic engineering, that must be
coupled to describe, develop and validate these systems of systems accurately. This
work presents a comprehensive survey of significant and recent advances in Co-VP relevant fields. We start by overviewing the work on control strategies and underlying communication infrastructures, focusing on their interplay. We also address a fundamental concern by presenting a cyber-security overview regarding these systems. Furthermore, we present and compare the primary initiatives to test and validate those systems, including simulation tools, hardware-in-the-loop setups, and vehicular testbeds. Finally, we highlight a few open challenges in the Co-VP domain. This work aims to provide a fundamental overview of highly relevant works on Co-VP topics, particularly by exposing their inter-dependencies, facilitating a guide that will support further developments in this challenging field.info:eu-repo/semantics/publishedVersio
Distributed Hybrid Simulation of the Internet of Things and Smart Territories
This paper deals with the use of hybrid simulation to build and compose
heterogeneous simulation scenarios that can be proficiently exploited to model
and represent the Internet of Things (IoT). Hybrid simulation is a methodology
that combines multiple modalities of modeling/simulation. Complex scenarios are
decomposed into simpler ones, each one being simulated through a specific
simulation strategy. All these simulation building blocks are then synchronized
and coordinated. This simulation methodology is an ideal one to represent IoT
setups, which are usually very demanding, due to the heterogeneity of possible
scenarios arising from the massive deployment of an enormous amount of sensors
and devices. We present a use case concerned with the distributed simulation of
smart territories, a novel view of decentralized geographical spaces that,
thanks to the use of IoT, builds ICT services to manage resources in a way that
is sustainable and not harmful to the environment. Three different simulation
models are combined together, namely, an adaptive agent-based parallel and
distributed simulator, an OMNeT++ based discrete event simulator and a
script-language simulator based on MATLAB. Results from a performance analysis
confirm the viability of using hybrid simulation to model complex IoT
scenarios.Comment: arXiv admin note: substantial text overlap with arXiv:1605.0487
From MANET to people-centric networking: Milestones and open research challenges
In this paper, we discuss the state of the art of (mobile) multi-hop ad hoc networking with the aim to present the current status of the research activities and identify the consolidated research areas, with limited research opportunities, and the hot and emerging research areas for which further research is required. We start by briefly discussing the MANET paradigm, and why the research on MANET protocols is now a cold research topic. Then we analyze the active research areas. Specifically, after discussing the wireless-network technologies, we analyze four successful ad hoc networking paradigms, mesh networks, opportunistic networks, vehicular networks, and sensor networks that emerged from the MANET world. We also present an emerging research direction in the multi-hop ad hoc networking field: people centric networking, triggered by the increasing penetration of the smartphones in everyday life, which is generating a people-centric revolution in computing and communications
Evaluating the feasibility of using smartphones for ITS safety applications

applying Intelligent Transportation Systems (ITS) proposals. The
low adoption rate of new ITS hardware and software products is
slowing down the market introduction of these solutions. In this
paper we present a driving safety application for smartphones
based on a warning dissemination protocol called eMDR.
The use of smartphones minimizes the hardware cost and
eliminates most of the adoption barriers; users will no longer have
to install new dedicated devices in their vehicles. Instead, they will
simply have to install an application in their smartphone. Our
application is integrated with a Navigation System which provides
access to road maps, current location, and route information.
We analyzed the behavior of the wireless channel and the GPS
location service under different conditions to assess the feasibility
of our proposal. Results showed that, in C2C communications,
smartphones are able to provide a reasonable degree of connectivity,
and that the degree of precision achieved is enough for
certain types of driving safety applications.This work was partially supported by the Ministerio de Ciencia e Innovación, Spain, under Grants TIN2011-27543-C03-01 and BES-2012-052673.Tornell, SM.; Tavares De Araujo Cesariny Calafate, CM.; Cano Escribá, JC.; Manzoni, P.; Fogue, M.; MartÃnez, FJ.
