Underwater Wireless Sensor Networks (UWSNs) are an enabling technology for many applications in commercial, military, and scientific domains. In some emergency response applications of UWSN, data dissemination is more important, therefore these applications are handled differently as compared to energy-focused approaches, which is only possible whe...

In this paper, we proposed a framework for accurate load forecasting which consists of two stage processes; feature engineering and classification. Feature engineering consists of feature selection and extraction. Relevant features are selected by combining Decision Tree (DT) and Recursive Feature Elimination (RFE) techniques. Moreover, Linear Disc...

Revolutionary development in integrated circuit miniaturisation facilitates the in-volvement of electronic sensors in every aspect of our life. This involvement results in a wide range of Wireless Sensor Network (WSN) applications in terrestrial, underwater and health care. However, small size poses power limitation on these sensors. In order to co...

In this paper, we propose a new Quality Link Metric (QLM), “Inverse Expected Transmission Count (InvETX),” in Optimized Link State Routing (OLSR) protocol. Then, we compare performance of three existing QLMs which are based on loss probability measurements: Expected Transmission Count (ETX), Minimum Delay (MD), and Minimum Loss (ML) in Static Wirel...

Wireless Body Area sensor Networks (WBANs) enable innovative health care monitoring. Limited energy source of a sensor node limits WBANs for long time monitoring of health care. Efficient energy utilization is therefore one of the research challenges in WBANs. In this research work we analysed energy utilization of popular routing techniques. We fo...
