Hybrid Protocols

Wireless sensor networks (WSN) are rapidly emerging as an interesting and challenging area of research in the field of communication engineering. This review work is different from other state-of-the-art literature as the MAC protocols discussed here are applicable both for homogeneous and heterogeneous networks. Performances like energy efficiency, cost optimization, throughput, bandwidth utilization, and scalability of the sensor network depend on MAC protocols, which are application-based. In the study, the authors have surveyed different MAC protocols with different merits and demerits. Based on the study, it is very hard to recommend any particular protocol as a standard for implementation as these are exclusively application dependent. The work can be further extended in terms of hybrid protocols, which may carry the advantages of the respective protocols along with energy-efficient criteria for practical implementation. Further cooperative WSN communication can be used for internet of things (IoT)-based systems, where the node placements and multi-operations concepts are of main concern.

Authentication Mechanism

Almost inevitable climate change and increasing pollution levels around the world are the most significant drivers for the environmental monitoring evolution. Recent activities in the field of wireless sensor networks have made tremendous progress concerning conventional centralized sensor networks known for decades. However, most systems developed today still face challenges while estimating the trade-off between their flexibility and security. In this work, we provide an overview of the environmental monitoring strategies and applications. We conclude that wireless sensor networks of tomorrow would mostly have a distributed nature. Furthermore, we present the results of the developed secure distributed monitoring framework from both hardware and software perspectives. The developed mechanisms provide an ability for sensors to communicate in both infrastructure and mesh modes. The system allows each sensor node to act as a relay, which increases the system failure resistance and improves the scalability. Moreover, we employ an authentication mechanism to ensure the transparent migration of the nodes between different network segments while maintaining a high level of system security. Finally, we report on the real-life deployment results.

Priority Schemes

Wireless sensor networks have recently been used to monitor bioelectric signals generated by the human body. However, since the dimensions and capabilities of the network nodes are small and limited, a problem is generated inherently by the energy consumption and radioelectric interference. In view of this, we propose two priority schemes to improve the performance of the network. In the first one, we aim at increasing the system lifetime by reducing the number of transmissions of nodes with low energy levels. In the second scheme, we aim at conveying priority data to the sink node as fast and efficient as possible. In the former scheme, users can be monitored for long time periods considering a low data generation. On the other hand, the latter scheme allows expediting transmission of important data when energy efficiency is not relevant. In this article, we mathematically model, analyze, and study the performance of the system for both priority schemes considering cognitive radio capabilities to make efficient use of resources and limit the radioelectric interference when the network transmits both continuous monitoring and event detection information. Numerical results provided in this work allow a careful parameter selection for practical implementation of BANETs.
