Analytical Estimation

Embedded wireless sensor networks are part of a strategy for implementing improved structural health and usage monitoring in rotorcraft. In order to realize this goal, methods of powering the embedded sensors have to be identified. One approach is to make the power supply become an integral part of the sensor. This integrated monitoring system will then be less intrusive and, therefore, easier to integrate into existing systems. Piezoelectric materials can be an important part of this strategy. One method to harness power is to use piezoelectric materials to recover energy lost due to vibration and rotation of the equipment. This recovered energy can then be used to provide energy to power sensors directly or to extend the lifespan of batteries which power the sensors. This paper investigates the potential of using strains on a rotating blade to power sensors during flight. The preliminary numerical investigation indicates that this may be a promising approach.

Wireless Sensor Networks motes have a small size, which leads to severe power supply restrictions. Much of the work on conserving power has been undertaken in the domain of routing protocols which deals with sending data in an efficient manner. In this paper a new scalar based protocol is proposed with a combination of multiple sub-base stations, that seeks to enhance the efficiency of protocol in terms of consumption of power and node failure tolerance. All the nodes are divided into regions, with each region having a sub- base station(sBS) and an arbitrary scalar value. Each sBS has lesser power supply and computation power compared to main station, but more of the mentioned metrics with respect to the sensor motes. Previous studies have described various paradigms and metrics for routing protocols and the placement of base stations. In this paper, the said algorithm is proposed, and its efficiency is analysed.

Uninterrupted power supply through electrical grid is not possible for many remote areas like dense forest, hill areas, and deserts. The objective of the proposed work is to generate stand alone electricity using steam powered gravity assisted SP system for remote WSN applications. The proposed design drives the generator by triggering gravity force using steam powered cylinders with high thermal efficiency. The proposed SP system is used to recharge the battery systems of UAVs in remote sites thereby the UAVs are further used to recharge the remote wireless sensor nodes using laser beam transmissions.

Wireless sensor networks (WSNs) has gain popularity due to their wide range of applications in almost all walks of life including industry controls, environmental monitoring, health, transportation, military, civil infrastructure, science, security and more. Wireless sensor nodes are cheap and tiny in size therefore its deployment is easier. They perform well in harsh environments where human intervention is almost difficult or not possible. However, wireless sensor networks are resource constraints and its power supply has been a big challenge to keep the sensor nodes functional for a longer period. Advancement in low power electronics helped a lot but the use and maintenance of conventional batteries with a limited life span cannot address the power supply problem effectively in a long run. Therefore, harvesting energy from ambient environment is an effective alternative both in terms of power and cost, which can help sensor networks to live longer. This chapter mainly focuses on different possible energy sources available in ambient environment and current technological mechanism to harvest energy for WSNs.
