Reconfiguring TDMA Communications for Dynamic Formation of Vehicle Platoons

Platooning is a promising concept used within the Intelligent Transportation System to increase efficiency and safety of road transportation. It is based on periodically sharing the kinematic status of the platoon members to allow reducing inter-vehicle distances in a safe way. This coordination is automatic and depends heavily on the wireless channel. A common technique to improve the channel properties is to ...

Assessing the ESP8266 WiFi module for the Internet of Things

The Internet of Things (IoT) is experiencing rapid growth and being adopted across multiple domains. For example, in industry it supports the connectivity needed to integrate smart machines, components and products in the ongoing Industry 4.0 trend. However, there is a myriad of communication technologies that complicate the needed integration, requiring gateways to connect to the Internet. Conversely, using IE...

Feasibility of Gateway-Less IoT E-Health Applications

Machine-to-Machine (M2M) communications are a key enabler of Internet of Things (IoT) applications. One domain with growing interest in M2M/IoT is e-health, either for self-monitoring, home monitoring, or hospital systems. However, current sensing devices in this domain rely on short-range communication protocols that require a gateway (GW) for Internet connection. Smartphones have been proposed as GWs in mobil...

Impact of Platoon Size on the Performance of TDMA-Based MAC Protocols

Vehicular networks are a core component in Intelligent Transportation Systems (ITS) enabling communication among vehicles for collaborative applications. One example of such an application that may bring benefits in reducing travel time, fuel consumption and improving safety is platooning. This application coordinates a group of vehicles that travel together, doing automatic control of inter-distances and speed...

A Flexible TDMA Overlay Protocol for Vehicles Platooning

Vehicular Ad-hoc Networks (VANETs) can enable a wide range of vehicle coordination applications such as platooning. A good use of the communication channel is paramount for an adequate quality of service. Currently, IEEE 802.11p is the standard used in VANETs and relies on CSMA/CA, which is prone to collisions that degrade the channel quality. This has led to recent proposals for TDMA-based overlay protocols th...

A Evolução Doutrinária da Logística das Pequenas Unidades

Este Trabalho de Investigação Aplicada subordinado ao tema “Evolução Doutrinária da Logística das Pequenas Unidades” tem como objetivo analisar a doutrina existente e, face à reestruturação do Exército, verificar quais as implicações para as Pequenas Unidades escalão Grupo e escalão Esquadrão, nomeadamente Grupo de Carros de Combate e Esquadrão de Reconhecimento da Brigada Mecanizada.

Coordinating distributed autonomous agents with a real-time database: the CAMBA...

Interest on using mobile autonomous agents has been growing, recently, due to their capacity to cooperate for diverse purposes, from rescue to demining and security. However, such cooperation requires the exchange of state data that is time sensitive and thus, applications should be aware of data temporal coherency. In this paper we describe the architecture of the agents that constitute the CAMBADA robotic soc...
