This paper presents the design, fabrication and characterization of a wireless capacitive pressure sensor with directional RF chip antenna that is envisioned for the health monitoring of aircraft engines operating in harsh environments. The sensing system is characterized from room temperature (25°C) to 300°C for a pressure range from 0 to 100 psi. The wireless pressure system consists of a Clapp-type oscillator design with a capacitive MEMS pressure sensor located in the LC-tank circuit of the oscillator. Therefore, as the pressure of the aircraft engine changes, so does the output resonant frequency of the sensing system. A chip antenna is integrated to transmit the system output to a receive antenna 10 m away. The design frequency of the wireless pressure sensor is 127 MHz and a 2% increase in resonant frequency over the temperature range of 25 to 300 °C from 0 to 100 psi is observed. The phase noise is less than -30 dBc/Hz at the 1 kHz offset and decreases to less than -80 dBc/Hz at 10 kHz over the entire temperature range. The RF radiation patterns for two cuts of the wireless system have been measured and show that the system is highly directional and the MEMS pressure sensor is extremely linear from 0 to 100 psi.

In this paper, we unify the requirements of noncritical and health monitoring applications in Aircraft and Launchers. We present different challenges faced by wireless sensor networks to meet these requirements. We also propose a solution that provides an adaptive multichannel collision-free protocol for data gathering.

This paper presents a wireless leak detection and localization system, based on airborne ultrasonic acoustics and a fast-Bayesian inference technique. Leaks caused by micrometeoroid and orbital debris are major concerns for mission safety on the ISS and other pressurized space structures. A sensor system was designed and constructed to observe these ultrasonic signals and localize the leak. A novel algorithm combining angle of arrival, Bayesian inference, and tree-search is presented to calculate the leak location with any desired accuracy. Prototype of the leak detector will be demonstrated on the ISS in the 2016/2017 time frame, collecting valuable ultrasonics data in microgravity environments. Leak location calculations, system design, and preliminary results are presented in this paper.

This paper presents an end-to-end solution for the management of ION DTN nodes. This system allows the user to modify the contact plan for remote ION nodes, as well as handle reports which have been received from those nodes, with all communication between the manager and remote nodes performed over DTN. We implement an open-source reference solution for many of the issues faced in the interplanetary DTN network management, including safe typing, data archival, and end-user interaction.

Space-based solar power satellites can be used to gather solar energy in space and beam it on Earth through microwaves. Developing inexpensive ground stations to harvest microwave energy and to convert it into usable power without affecting the use of land for agriculture will make this technology more affordable and non intrusive. To this end, we present a working design for transparent fabricated, 5.8 GHz rectennas using a modified off-the-shelf desktop ink-jet printer. Preliminary low power tests show the ability of the prototypes to convert microwaves into sufficient DC power to turn on an LED; moreover, the verified substrate transparency to ultraviolet radiations suggests the possibility of deploying ground stations above land usable for agriculture.

Delay-tolerant Networking protocols render a huge variety of novel communication scenarios possible. One of them is the so called Ring Road approach, a world-wide message-ferry network built upon Low-Earth Orbit (LEO) satellites used to transfer data between different ground stations. By this approach a world-wide communication network may be deployed at very low cost which allows for ad-hoc integration of ground stations into the overall network. Thus, it is possible to route data between isolated regions of the world and the Internet without explicit configuration effort. Essential for bringing this concept to realization is a neighbor discovery protocol enabling LEO satellites to discover new ground stations. The aim of this paper is to discuss the DTN IP Neighbor Discovery (IPND) protocol as a basis for a dedicated discovery approach. The resulting adapted version of IPND has been integrated into an existing DTN protocol implementation intended to be used on low-cost LEO satellites such as CubeSats. A technical realization has stood the test of practice and, thus, confirmed the applicability of the protocol for dynamic ground station discovery in a Ring Road network.

With recent advancements of Information and Communication technologies (ICT), Internet of things (IoT) development has just started creating a significant value across people, processes and organizations. There are numbers of applications across energy, transportation and public safety sectors that have linked with economic growth in GDP and therefore, governments are taking serious actions to enhance ICT and IoT penetration across their countries and achieve economies of scale. In future, it can be easily anticipated to meet growing demand, IoT applications scale will reach to millions of sensor devices in a few sq. kilometers area in order to transform traditional cities towards smart cities and accommodate the urbanization pressures. With the growing demand of data hungry devices and deployment of millions of sensors in a certain place will eventually increase size of information and data transmission flow through the sensor devices itself and infrastructure network nodes and then millions of IP addresses will be needed to provide connectivity. Wireless Sensor Networks implementation under internet of things context likely to approach limitations of network bandwidth availability and the cost of IoT infrastructure will be extremely high if dedicated network resources deployed therefore this paper proposed the innovative architecture using Software Defined Networks (SDN) to provide on demand and efficient network resources for low power wireless personal area network (6LowPAN) devices. This proposed architecture model will also strengthen the applications of IoT in either side i.e. control and monitoring.

This paper presents the development of a newly designed wireless piezoelectric (PZT) sensor platform for distributed active structure health monitoring (such as aircraft wings and bridges). The developed wireless PZT-sensor network features real-time data acquisition with high sampling rate up to 12.5MSPS (sample per second), distributed lamb-wave data processing and energy saving by reducing the amount of data in wireless transmission. In the proposed wireless PZT network, a set of PZT transducers deployed at the surface of the structure, and a lamb wave is excited and its propagation characteristics within the structure are inspected to identify possible damages. The developed wireless node platform benefits from a digital signal processor (DSP) of TMS320F28335 and an improved IEEE 802.15.4 wireless data transducer RF233 with up to 2Mbps data rate. Each node supports up to 8 PZT transducers, one of which may work as the actuator generating the Lamb wave at an arbitrary frequency, while the responding vibrations at other PZT sensors are sensed simultaneously. In addition to hardware, embedded signal processing and distributed data processing algorithm are designed as the intelligent `brain' of the proposed wireless monitoring network to extract features of the PZT signals, so that the data transmitted over the wireless link can be reduced significantly.

Power consumption and lifetime are essential features of sensor networks. On the one hand, the power consumption should be as low as possible to enable an energy-aware system. On the other hand, the lifetime should be as long as possible to ensure for a comprehensive coverage. Especially, for application of sensor networks in extreme environments, it is also necessary to achieve high reliability over the whole lifetime. However, these features are contrary and they must be optimized simultaneously to achieve an optimal performance. In this paper, we thus study the minimization of the overall power consumption for any given lifetime and any required signal quality. First, a theoretical and challenging approach is proposed, which shows the feasible boundaries for both power reduction and achievability of a certain lifetime. Then, a practical approach is shown, which is nearly optimal and fits sufficiently together with the theoretical approach. Finally, selected results are visualized to show the performance of the new methods and to discuss the power consumption of the entire sensor network.
