A Constructive Interference-based flooding mechanism - using hardware-generated ACKs - is proposed to achieve highly reliable source-to-sink communication of very short critical packets in a wireless sensor network working in harsh environments. Constructive interference is only achieved if the senders synchronize their packet transmissions with sub-microsecond accuracy. In order to achieve the required...
Creating, deploying and configuring applications for Internet of Things (IoT) scenarios today remains complex and costly for many users. The MicroPnP platform addresses this complexity problem and provides a true zero-configuration and standards-based solution that radically reduces the cost of acquiring, building, and operating wireless sensing and actuation IoT systems at scale. MicroPnP combines...
The IEEE 802.15.4-2015 standard defines a number of Medium Access Control (MAC) layer protocols for low-power wireless communications in the IoT. Originally defined in the IEEE 802.15.4e amendment, TSCH (Time Slotted Channel Hopping) is among the proposed mechanisms. TSCH is a scheme aiming to guarantee network reliability by keeping nodes time-synchronised at the MAC layer. In order to ensure successful...
In this poster paper we present a data dissemination transmission abstraction for over the air programming (OAP) protocol which is fundamentally different from the previous hop-by-hop transmission protocols. Instead of imposing the greedy requirement that at least one node in the ith hop receives all packets before transmitting packets to the next hop and its neighbours, we take advantage of the spatial...
There is an urgent need for smart transportation, to enable safer, efficient and more enjoyable journeys, and connected vehicles are a way to realise that. Modern cars feature embedded systems that monitor and manage all the critical sensors and actuators. The vehicle connectivity can be further extended with Vehicle-to-Vehicle (V2V) technology, which allows cars to exchange that collected information...
Monitoring network statistics is important for the maintenance and infrastructure planning for the network service providers. In this demonstration, we will showcase an initial analysis of a general purpose network monitoring platform for high speed mobile networks. The developed platform is the basis for performing complex real-time analysis such as application usage behaviour, security analysis,...
In 2013, 85% of the peach production in the Mendoza region (Argentina) was lost because of frost. In a couple of hours, farmers can lose everything. Handling a frost event is possible, but it is hard to predict when it is going to happen. The goal of the PEACH project is to predict frost events by analyzing measurements from sensors deployed around an orchard. This demo provides an overview of the...
The Industrial Internet of Things (IIoT) vision relies on reliable low-power wireless technologies and a complete standardized protocol stack that brings Internet connectivity to constrained end devices. Currently IEEE802.15.4-2015 TSCH provides reliability over low-power wireless technologies and the IETF has defined a protocol stack that is suitable to constrained devices. Open-source initiatives...
This demo paper describes the usability and effectiveness of our distributed energy measurement system for WSNs. The system is composed of several micro-controller-based oscilloscopes - named PotatoScope. The intention of PotatoScope was to enable a scalable and dependable energy measurement for challenging environmental conditions, e.g., WSN outdoor deployments. We will present the general architecture...
Nowadays, with the development of micro-electro- mechanical technologies, sweep coverage are more and more popular in wireless sensor networks, which is also applied widely in other scenarios, such as message ferrying and data routing in the ad-hoc network. In order to reduce the sweep cycle and the number of required mobile sensors, we propose the \emph{Distance-Sensitive-Route-Scheduling} (DSRS)...
In Internet of Things (IoT), numerous and diverse types of sensors generate a plethora of data that needs to be stored and processed with minimum loss of information. This demands efficient compression mechanisms where loss of information is minimized. Hence data generated by diverse sensors with different signal features require optimum balance between compression gain and information loss. This...
