This research-in-progress proposes an approach that accounts for social and institutional issues in the design and implementation of sensor networks for air-quality monitoring. The proposed approach is evaluated through action research, in an initiative that seeks to enhance the air-quality sensor network of a Megalopolis based on data analytics. Preliminary findings indicate that the proposed approach improves access to resources, enhances the validity of design, and increases buy-in for implementation.

Reservation-based and contention-based MAC protocols have their own advantages in data transmissions under mobile sensor networks. This paper presents a quantitative analysis of two types of MAC protocols in throughput, delay, and energy efficiency under various traffic loads environments using queueing theory. The analytical and simulation results show the design strategies of hybrid MAC protocols for mobile dynamic traffic scenarios.

Available algorithms for the distributed construction of connected dominating sets in mobile ad hoc networks are inapplicable or suffer from a high complexity. This is mainly due to the resource-restricted nature of wireless devices, such as sensor nodes, and the error-prone character of the communication medium. This work introduces and evaluates a new local, probabilistic self-stabilizing algorithm providing fault-tolerance and scalability for networks of high density.

In this paper, we present OVERTAKE, an opportunistic routing protocol for Time-Slotted Channel Hopping (TSCH). OVERTAKE combines (1) opportunistic routing, (2) concurrent transmissions and (3) TSCH. We show that this novel combination enables low-latency, central scheduling withstanding node failures. Our initial results show its ability to withstand node failures of up to 40% of nodes of a flow while keeping minimal latency.

In this paper, we investigate the manner in which energy consumption in drone deliveries is affected by windy environmental conditions. We know in fact that the energy consumption of the drone will depend on the static and dynamic parameters of the scenario where it moves and according to these it decides, during the mission, to detour from the originally planned path to take advantage of the wind changes. In order to validate this, we simulate possible deliveries among fixed destinations relying on a real data-set of recorded winds obtained from different weather stations in Corsica, France. For our analysis, we will mainly concentrate on the evaluation of the delivery scheme proposed in the literature, where completing a delivery means finding a cycle for the drone that is feasible, i.e., that can be completed with the available energy autonomy of the drone.

In recent years, wireless sensor networks offer cost-effective solutions to various surveillance and tracking applications with the developments in sensor techniques. In many of these applications, sensor nodes that are equipped with directional sensors and they operate autonomously in unattended environments. The deployment strategy of directional sensor nodes is critical to improve target detection and tracking accuracy. In this paper, deployment of passive infrared motion (PIR) sensors is analyzed in terms of coverage issue. A PIR sensor Deployment (PSD) problem is addressed using deployment schemes that are based on computational geometry. Finally, the performance of deployment schemes is evaluated in a Java based simulation environment.

Low-power operation of power-hungry MOX sensors is usually achieved by duty cycling them periodically. However, a difficulty arises if a sensor is operated at irregular time intervals due to intermittent energy availability in energy-neutral or batteryless applications. In this work, we propose a compensation method which re-maps on-demand measurements to virtually duty-cycled readings in the value domain by taking the duration of the last off-time into account. We evaluate our compensation algorithm based on Sensirion's SGP30 sensor and achieve up to 79% accuracy improvement compared to uncompensated measurements.
