New Conference Paper: Self-Adaptive Transmission Power Controller for WSANs

I’m excited to share that our latest conference paper has been presented! 🎉 This time, we’ve explored how the communication range for each node evolves using an energy-saving self-adaptive transmission power controller in wireless sensor and actuator networks (WSANs). Our approach aims to automatically adapt to surrounding changes while maintaining good connectivity and saving energy (Lucas-Martínez et al., 2015). This conference paper presents an dynamic study for the self-adaptive strategy presented in (Hernández-Díaz et al., 2015).

Key Highlights

Self-Adaptive Control: We developed a controller that adjusts the transmission power of each node based on environmental changes, ensuring efficient energy use.
Energy Efficiency: Our approach helps extend the lifespan of WSANs by reducing unnecessary energy consumption.
Real-World Testing: We tested our model in an outdoor scenario, showing promising results in maintaining connectivity and saving energy.

The deployment of the nodes in a Wireless Sensors and Actuators Network (WSAN) is typically restricted by the sensing and acting coverage. This implies that the locations of the nodes may be, and usually are, not optimal from the point of view of the radio communication. And also when the transmission power is tuned for those locations, there are other unpredictable factors that can cause connectivity failures, like interferences, signal fading due to passing objects, and of course, radio irregularities. A control based self-adaptive system is a typical solution to improve the energy consumption while keeping a good connectivity. In this paper, we explore how the communication range for each node evolves along the iterations of an energy saving self-adaptive transmission power controller when using different parameter sets in an outdoor scenario, providing a WSAN that automatically adapts to surrounding changes keeping a good connectivity. The results obtained in this paper show how the parameters with the best performance keep a k-connected network, where k is in the range of the desired node degree plus or minus a specified tolerance value. In addition, the worst performance shows how a bad parameters choice can create isolated islands, groups of nodes disconnected from the rest of the network

The solutions to cope with new challenges that societies have to face nowadays involve providing smarter daily systems. To achieve this, technology has to evolve and leverage physical systems automatic interactions, with less human intervention. Technological paradigms like Internet of Things (IoT) and Cyber-Physical Systems (CPS) are providing reference models, architectures, approaches and tools that are to support cross-domain solutions. Thus, CPS based solutions will be applied in different application domains like e-Health, Smart Grid, Smart Transportation and so on, to assure the expected response from a complex system that relies on the smooth interaction and cooperation of diverse networked physical systems. The Wireless Sensors Networks (WSN) are a well-known wireless technology that are part of large CPS. The WSN aims at monitoring a physical system, object, (e.g., the environmental condition of a cargo container), and relaying data to the targeted processing element. The WSN communication reliability, as well as a restrained energy consumption, are expected features in a WSN. This paper shows the results obtained in a real WSN deployment, based on SunSPOT nodes, which carries out a fuzzy based control strategy to improve energy consumption while keeping communication reliability and computational resources usage among boundaries.
