Performance monitoring and state estimation are promising techniques to ensure high reliability in Internet of Things (IoT). A major data-driven approach that addresses the decentralized and heterogeneous nature of IoT is distributed computing. Values from physical measurements and temporal dimension in transmitted sensor data can be analyzed in a distributed manner for state estimation. In this paper, we discuss a smart home energy utilization problem and the effects of climatic conditions. We focus on determining patterns, correlations and predicting weather attributes in a distributed and scalable manner using Message Passing Interface (MPI). Our results show that our distributed approach is scalable up to 24 nodes or processes, which can further scale up to 1000 nodes or processes depending on the number of indivisible subtasks that need to be computed. We also compare the execution time for the distributed tasks and notice a performance gain due to parallelization. Furthermore, we develop a model based on Long Short-Term Memory (LSTM) to estimate the expected energy to be utilized in a smart home environment. We evaluate our work using an IoT dataset to show the effectiveness of our approach.
