This paper outlines a novel scheme for predictive channel access methodology to enhance medium access reliability and reduce probability of interference in case of using IEEE 802.15.4 compliant WSN nodes under co-existence of communications for FBW applications. The performance of the proposed scheme is evaluated using real-world IEEE 802.1lg traffic, and the results show that free channel access rates of WSN nodes can be significantly improved.

This paper describes the design, development and analysis of an autonomous Quadrotor Unmanned Aerial Vehicle (UAV) that is controlled using fly-by-wireless technology. A communication protocol between the UAV and a Ground Control Station (GCS) is established to continuously send information from the on-board sensors to the GCS. There, a controller computes the control signal in real-time and sends it back to the UAV to act upon the actuators. An Inertial Measurement Unit (IMU) and a sonar are used as sensors to determine the attitude angles and the height of the UAV, respectively. A state-feedback controller is designed by pole placement. Considering the delays of the wireless network, a Lyapunov-Krasovskii functional is used to determine if the stability of the system is affected by the delay. Some results are presented from initial flight experiments in which attitude angles and altitude are stabilized.

In this paper, compact circularly polarized dual band microstrip patch antennas with multiple techniques are presented. Two patches as receiver and transmitter are printed on a FR4 substrate with relative permittivity of 4.4. Various techniques are employed to achieve circular polarization (CP). Defected ground plane (DGP) is utilized for size reduction. Simulated and measured results are presented for verification.

This paper conceptualizes an integrated clock-less and multipath-robust Impulse Radio-Ultra Wideband (IR-UWB) transceiver for communication and localization puiposes. The ranging scheme is based on the use of the same transceiver installed both in the anchor and in the mobile nodes, for a Two-Way-Ranging (TWR) Time-of-Flight (ToF) estimation. The transmitter and receiver are implemented in a 130 nm RFCMOS technology. This paper presents the block scheme of the transmitter and the receiver, as well as the ranging scheme, prior to the chip validation and test.

This paper proposes an oscillator design capable of achieving high data transmission rates of up to 1.5 Gbps with a modulation scheme of 256 QAM at E-band frequencies. A low phase noise oscillator and high quality factor resonator are implemented in this work. The proposed cavity resonator design is embedded in a low cost gold plated brass casing. Eigenmode simulations yield an unloaded quality factor in excess of 5800 at 20 GHz. The low phase noise oscillator comprises of commercially available and low cost components surface mounted on a low loss millimeter-wave substrate. The proposed 20 GHz oscillator makes use of a frequency doubler to drive a sub-harmonically pumped mixer aimed for E-band frequencies of 80 GHz. The expected phase noise of the oscillator is better than −103 dbc/Hz with 100 kHz offset while operating at 80 GHz.

This paper presents the results of an assessment process carried out in the department of Safety-Critical Systems & Systems Engineering inside the Institute of Flight Systems of the German Aerospace Center (DLR) for selecting the technological foundation to be used on future airborne intra-aircraft wireless applications. This paper summarizes the requirements imposed by the applications to be implemented wirelessly onboard an aircraft and introduces the benchmark criteria selected for comparing the various wireless standards. Finally, it describes the multi-criteria decision making (MCDM) and sensitivity analysis methods used for supporting the objective selection processes of the most suitable wireless technologies for different sets of requirements. The work presented here as a part of the research work accomplished in DLR has determined that fundamental parameters for the design of real-tune, deterministic data communication systems, like jitter among others must be defined before their technology foundation can be accurately selected. It has also identified some of the technology gaps which limit the implementation of wireless technologies for supporting airborne applications.

In recent years, wireless technologies in the aerospace field have attracted significant interest from industry professionals. This research addresses the issue of selecting optimal frequency bands that may be employed within an aircraft environment. The optimality takes into account the specific type of application (Entertainment, sensors), its environment, and regulatory as well as performance aspects. This poster exposes the previous studies on channel characterization and describes the current work for CRIAQ, AVIO-402 project.

During the past several years, work has been ongoing at corporate, goverment laboratory, and university research group to develop passive wireless surface acoustic wave (SAW) sensors and sensor-tags. These efforts have led to SAW sensors that operate wirelessly in enviroments coosiderably more extreme than those in which silicon-based sensors can operate. Advances have also been made in sensor coding, allowing production of small sets of sensors that can be individually read. The use of SAW devices as wireless interfaces to external impedance varying and voltage producing sensors and devices has also been demonstrated. This article provides a brief overview of recent advances made in this technology by several companies.

In this modern society each one of us do have a mobile phone with us and some have more than one. This fast growth in cell phone usage symbolifies utilization of energy in a vast scale. This enhances the speed of depletion of energy resources. The advancements in technology have gifted us mobile phones that are capable of functioning for months without charging. This was considered as a great achievement at the time of launch, still engineers are working on mobiles that are capable of functioning with renewable energy. In our paper we have proposed an eco friendly technique that could be imparted in mobile phone, so that device would be charging around the clock. We have devised our project in such a way that it makes efficient usage of renewable resources from which power is being harvested.
