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.

In recent years, wireless sensor networks (WSNs) have grown dramatically and made a great progress in many applications. But having limited life, batteries, as the power sources of wireless sensor nodes, have restricted the development and application of WSNs which often requires a very long lifespan for better performance. In order to make the WSNs prevalent in our lives, an alternative energy source is required. Environmental energy is an attractive power source, and it provides an approach to make the sensor nodes self-powered with the possibility of an almost infinite lifetime. The goal of this survey is to present a comprehensive review of the recent literature on the various possible energy harvesting technologies from ambient environment for WSNs.

Application Requirements

Enabling technologies for wireless sensor networks have gained considerable attention in research communities over the past few years. With the advantage of high power density, piezoelectric vibration energy harvester is promising in self-powered wireless sensor networks. In this work, modeling of piezoelectric generator based on a bimorph cantilever is discussed and functional characteristics of the bimorph piezoelectric cantilever are given. Corresponding step-up energy harvesting circuit according to the practical application requirements is developed. Then an integrated environmental vibration energy harvester with a size of approximately 83mm × 55mm × 12mm was fabricated. The results shows that the energy harvester is able to provide a stable 3.3V supply voltage under 37Hz working frequency.
