Wireless sensor networks (WSN) are deployed in a multitude of applications both in industrial and academic fields. In recent years, due to the emerge of Internet of Things (IoT) technologies and Vehicle2X communication scenarios, novel challenges for wireless sensor network platforms - regarding hardware and software - arose. Thus, challenges known from big data processing have reached the WSN scope and consequently approaches and methods have been devised to handle these. One such approach is queriable wireless sensor networks which enable their users the specification of sensing tasks in a declarative way without the need to re-program nodes in case the application requirements change. As many current WSN applications feature active parts with which nodes can directly influence their environment, the term wireless sensor actuator networks (WSAN) has been coined, setting such networks apart from solely passively measuring networks.In this article, we will present a short introduction to big data processing in wireless sensor networks which motivates the usage of queriable networks. We will show that in order to enable a WSAN to carry out actions energy-efficiently and in a timely manner, an event-based action model is favorable. Additionally, we will demonstrate how such an event system can be used to improve sub query performance in WSNs. We conclude with an evaluation regarding the benefit of combining this approach with wake-up receiver technologies based on a qualitative energy efficiency definition for WSN.

Accurately assessing the quality of road links is essential for effectively sharing critical messages in dynamic vehicular network environments. Unfortunately, existing literature lacks models to estimate the quality of links between infrastructure and vehicles due to the complexity and variability of vehicular communication networks, including channel variations and interference patterns. To address this gap, we propose a prediction model based on supervised machine learning to estimate the Packet Reception Rate (PRR) on the road. Our model updates communication zones dynamically to align with traffic conditions. We train and evaluate our model using a dataset generated from a realistic mobility scenario simulated using NETSIM and SUMO. Our performance tests indicate promising results in terms of prediction accuracy. This work is an important step toward establishing an efficient and reliable scheme for disseminating alert messages, considering the fluctuations in traffic conditions and vehicular mobility.
