Item Improving on the Reliability of Wireless Sensor Networks(Proceedings - 15th International Conference on Computational Science and Its Applications, ICCSA 2015, 2015-06) Engmann, F.; Abdulai, J.-D.; Azasoo, J.Q.The application of wireless sensor networks is gradually gaining popularity in ubiquitous computing. They are used for military surveillance, home automation and monitoring, underwater surveillance, wearable sensor and many others. With their way of deployment and use, these tiny motes are mostly vulnerable to attacks and their mode of transfer of data depletes battery power leaving motes dead after a short while. In this paper an algorithm that can be used to minimize the energy consumed by sensor nodes communicating over multihop links is proposed. The algorithm employs unequal clustering technique taking into consideration the distance of the motes from the base station. Our algorithm considers a base station with sparsely distributed nodes that may not all receive adequate signal strength from the base station. Intuitive performance analysis of the proposed algorithm was done in comparison with EEUC and EAUCF considering their energy metrics and clustering techniques. From the preliminary results obtain, our algorithm performs better than the others and hence more stable and energy efficient clustering algorithm. © 2015 IEEE.Item Understanding the effects of techno-stress on the performance of banking staff(Int. J. Business Continuity and Risk Management, 2016) Owusu-Ansah, S.; Azasoo, J.Q.; Adu, I.N.The technological revolution has undoubtedly brought about many changes in the modern workplace. Although it has allowed work to be carried out faster and more efficiently, many employees are not comfortable with its implementation since it involves change and uncertainty. As a result, users experience technological stress (techno-stress), which may have negative consequences on work places like commercial banks. This paper aims at investigating the effects of techno-stress on employees in the banking sector. A survey methodology that involves self-administered questionnaires to solicit data from 400 banking staff of commercial banks was employed. The employees revealed that ICTs create mental pressure, sense of anxiety and pessimism, as they have to keep up with the fast advancing pace of the new ICTs. Our study reveals that techno-stress has a negative impact on employee performance. It is recommended that the management of commercial banks, and IT professionals provide a better environment, alternative power supply and adequate training programs.Item Understanding the effects of techno-stress on the performance of banking staff(Int.
