Wireless sensor Networks (WSNs) consist of a large number of small size, limited energy nodes distributed over an Area of Interest (AoI), in order to perform sensing and monitoring operations. Due to their limited energy sources, it is of utmost importance to optimize the nodes' energy consumption thus prolonging the sensors' lifetime. In this paper, an optimization problem is formulated and solved to find the optimal location of the Cluster Head (CH) node with respect to the other nodes such that the communication path loss of the nodes with respect to the CH is minimized. Simulation results have shown that the proposed Cluster Head Positioning Optimization (CHPO) mechanism has proven its effectiveness when compared with the literature work, in reducing the nodes' energy consumption, thus increasing the network lifetime.

The healthcare system is a distributed collaborative system and the sensitivity of the medical data is one of the most important requirements. Preventing unauthorized access to healthcare information and data sharing security in the healthcare environment are critical processes that affect the credibility of the system. To achieve this goal and to meet the requirements of the healthcare system, access control is an important measure to realize the safe sharing of resources. The attribute-based access control (ABAC) model meets the complex security requirements of large and complex systems and provides a dynamic, flexible and scalable solution. The main obstacle to deploying ABAC is the precise development of ABAC policies. Manually developing access control policies is tedious, time-consuming and error prone. Most systems have high-level requirement specifications, which are written in natural language. These natural language (NL) documents have the intended access control policies for the systems. In this paper, we propose a new approach towards extracting policies from natural language documents. By fully taking advantage of Bidirectional Encoder Representations from Transformers (BERT) and Semantic role labeling (SRL), we are able to correctly identify access control policy (ACP) sentences with an average F1 score of 85% and correctly extract rules with an average F1 score of 72%, which outperforms the state-of-the-art and leads to a performance improvement of 7% and 2% respectively over the previously reported results.

Novel mobile information systems are being developed with the use of smartphones. The traditional applications of wireless sensor networks such as environmental monitoring, health care, and transportation are being realized by many mobile social network applications. Smartphones forward various onboard sensor data using a store-carry-forward way to the central repositories over the internet. In this paper, inter contact time distribution of each smartphone user with other users is utilized for efficient sensor data routing. A novel threshold-based approach is used to estimate future interconnection times. Human mobility based Weighted Relaying Algorithm (Hm-WRA) is proposed for routing in opportunistic mobile sensing systems. The proposed protocol performs almost 15% to 20% better compared to an intercontact time based shortest path routing algorithm named CHARON in terms of the data delivery ratio with proper selection of threshold value at each node.

Forecasting spatio-temporal correlated time series of sensor values is crucial in urban applications, such as air pollution alert, biking resource management, and intelligent transportation systems. While recent advances exploit graph neural networks (GNN) to better learn spatial and temporal dependencies between sensors, they cannot model time-evolving spatio-temporal correlation (STC) between sensors, and require pre-defined graphs, which are neither always available nor totally reliable, and target at only a specific type of sensor data at one time. Moreover, since the form of time-series fluctuation is varied across sensors, a model needs to learn fluctuation modulation. To tackle these issues, in this work, we propose a novel GNN-based model, Attention-adjusted Graph Spatio-Temporal Network (AGSTN). In AGSTN, multi-graph convolution with sequential learning is developed to learn time-evolving STC. Fluctuation modulation is realized by a proposed attention adjustment mechanism. Experiments on three sensor data, air quality, bike demand, and traffic flow, exhibit that AGSTN outperforms the state-of-the-art methods.
