This manuscript presents a system that can generate a 2D grid map and a 3D voxel model of an environment by fusing multiple sensors integrated into a robot. The fusion of these sensors is done by utilizing Robot Operating System (ROS) and some of its libraries. The sensors that are fused in the robot are a Light Detection and Ranging (LIDAR), Inert...

Smart Mobility is a concept within Smart Cities, which are "cities in which ICT is merged with traditional infrastructures, coordinated and integrated using new digital technologies" [9]. According to the United Nations 2/3 of world population is expected to live in cities by 2050. Therefore, mobility is a keystone for providing citizens access to...

In recent times, we have been witnessing the development of multiple applications and deployment of services through the indoors location of people as it allows the development of services of interest in areas related mainly to security, guiding people, or offering services depending on their localization. On the other hand, at present, the deploym...

Indoor positioning is a problem that has not yet been solved efficiently and accurately. In outdoors the most effective solution is the Global Position System (GPS), but it cannot be used indoors due to the weakening of the signal, so other solutions have been studied. These approaches could be applied to define a map for the guidance of blind peop...

This work aims to monitor air quality in places where humans spend most of their time, such as workplaces and homes. Radon gas is a naturally occurring, colourless, odourless and tasteless gas that accumulates in enclosed spaces. It is a radioactive element produced by the decay of its natural parent elements, uranium and thorium, which is harmful...

This research work presents a detailed survey about Computational Intelligence (CI) applied to various Hotel and Travel Industry areas. Currently, the hospitality industry’s interest in data science is growing exponentially because of their expected margin of profit growth. In order to provide precise state of the art content, this survey analyses...

In recent years, indoor localization systems based on fingerprinting have had significant advances yielding high accuracies. Those approaches often use information about channel communication, such as channel state information (CSI) and received signal strength (RSS). Nevertheless, these features have always been employed separately. Although CSI p...

In a fully connected world where data freely flows and people can travel anywhere a lot of research has been conducted regarding Smart Mobility, which aims to improve all sorts of traffic matters, from Vehicle Data to Traffic flow management. However, it is also surprising how this topic has been applied in such a small extent to Tourism, an area t...

The Canary Islands are a well known tourist destination with generally stable and clement weather conditions. However, occasionally extreme weather conditions occur, which although very unusual, may cause severe damage to the local economy. The ViMetRi-MAC EU funded project has among its goals, managing climate-change-associated risks. The Spanish...

Indoor localization has received tremendous attention in the last two decades due to location-aware services being highly demanded. Wireless networks have been suggested to solve this problem in many research works, and efficient algorithms have been developed with precise location and high accuracy. Nevertheless, those approaches often have high c...

Indoor localization estimation has become an attractive research topic due to growing interest in location-aware services. Many research works have proposed solving this problem by using wireless communication systems based on radiofrequency. Nevertheless, those approaches usually deliver an accuracy of up to two metres, since they are hindered by...

Mobility is an essential part of modern societies.

Indoor localization has gained considerable attention over the past decade because of the emergence of numerous location-aware services. Research works have been proposed on solving this problem by using wireless networks. Nevertheless, there is still much room for improvement in the quality of the proposed classification models. In the last years,...

Ambient Assisted Living (AAL) has become an attractive research topic due to growing interest in remote monitoring of older people. Development in sensor technologies and advances in wireless communications allows to remotely offer smart assistance and monitor those people at their own home, increasing their quality of life. In this context, Wirele...

Indoor positioning estimation has become an attractive research topic due to the growing interest in location-aware services. Many research works have been proposed on solving this problem by using wireless networks. Nevertheless, there is still much work needed to achieve high accuracy levels. In the last years, the emergence of visible light comm...

In the last few years, the increasing use of LEDs in illumination systems has been conducted due to the emergence of Visible Light Communication (VLC) technologies, in which data communication is performed by transmitting through the visible band of the electromagnetic spectrum. In 2011, the Institute of Electrical and Electronics Engineers (IEEE)...

Indoor position estimation has become an attractive research topic due to growing interest in location-aware services. Nevertheless, satisfying solutions have not been found with the considerations of both accuracy and system complexity. From the perspective of lightweight mobile devices, they are extremely important characteristics, because both t...

Visible Light Communications (VLC) uses visible light spectrum as transmission medium for communications. VLC has gained recent interest as a favorable complement to radio frequency (RF) wireless communications systems due to the ubiquity and wide variety of applications. In 2011 the Institute of Electrical and Electronic Engineers published the st...

The emerging IEEE 802.11 family of wireless technologies has shown tremendous growth and acceptance as a last hop wireless solution in Local Area Networks (LANs). The use of multimedia networking applications has brought more requirements to the network, creating a need for end-to-end quality of service (QoS). In this context, the standard introduc...

A mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links, which cooperatively and spontaneously form an IP-based network. These networks are infrastructure-free where central administration or configuration by the user are impractical. On the other hand, the Dynamic Host Configuration Protocol (DHCP) was d...

One of Wireless Local Area Networks (WLAN) main drawbacks, when compared to wired networks, is that WLAN are less predictable and efficient. Wireless physical medium is harder to be controlled than physical wire. WLAN medium is also unlicensed, and thus susceptible to interferences produced by other devices. Therefore, great effort is being done in...

A mobile ad hoc network is a group of mobile, wireless nodes which cooperatively and spontaneously form an IP-based network. In order to make computing and communication, a node in an IP-based network must be configured with an IP address. On the other hand, the main problem in an ad hoc network is the mobility of the nodes which can lead to freque...

How to properly handle the multiple conflicting objectives in automatic indoor wireless network planning is a matter of major concern. This issue has been usually addressed establishing beforehand some kind of preferences on the objectives. However, the high complexity of the indoor design problem makes any "a priori" assumption unreliable. This pa...
