“…An AT86RF212 has a sensitivity of −110 dBm at 20 kb/s, −108 dBm at 40 kb/s, and −101 dBm at 250 kb/s. This increased sensitivity corresponds to a greater communication region, but as shown in [1] for aeronautical usecases a sensitivity of −80 dBm is sufficient to support a communication region of about 10 m.…”

“…Amongst others, this time basis is necessary to enable some Medium Access Control (MAC) schemes, to determine the occurrence of special events, or to start measurements at the same time. For instance, structural health monitoring and flight test installations are expected to be very beneficial in future aircrafts [1]. Apart from the general saving of cabling (weight) and installation effort, permanent monitoring of the structural health of an aircraft with wireless sensors is one of the premises of maintenance on demand.…”

In wireless sensor networks (WSNs) it is often required to have a common time basis for all sensor nodes. Due to clock drift it is necessary to re-synchronize the nodes repeatedly to keep the common time basis. But this re-synchronization can be power demanding. We present an energy-efficient approach which can bound the synchronization error to a certain limit. Either duty-cycled transceivers or wake-up receivers (WURs) can be used. Using WURs is the more energy-efficient and robust approach but needs special hardware.

“…In [76], results of a measurement campaign conducted with a wireless sensor network (WSN) consisting of 500 sensor nodes organized in three cells with two redundant access points per cell, deployment inside an aircraft is presented. It is concluded that the packet error rate could be decreased more than four times by the robust and scalable TDMA protocol that exploited spatial diversity provided by redundant access points.…”

Novel Air Traffic Management (ATM) strategies are proposed through the Next Generation Air Transportation (NextGen) and Single European Sky for ATM Research (SESAR) projects to improve the capacity of the airspace and to meet the demands of the future air traffic. The implementation of the proposed solutions leads to increasing use of wireless data for aeronautical communications. Another emerging trend is the unmanned aerial vehicles. The unmanned aerial systems (UASs) need reliable wireless data link and dedicated spectrum allocation for its operation. On-board broadband connectivity also needs dedicated spectrum to satisfy the quality of service (QoS) requirements of the users. With the growing demand, the aeronautical spectrum is expected to be congested. However, the studies revealed that the aeronautical spectrum is underutilized due to the static spectrum allocation strategy. The aeronautical communication systems such as air-air and airground communication systems, inflight infotainment systems, wireless avionics intra-communications (WAIC), and UAS can benefit significantly from the introduction of cognitive radio based transmission schemes. This article summarizes the current trends in aeronautical spectrum management followed by the major applications and contributions of cognitive radio in solving the spectrum scarcity crisis in the aeronautical domain. Also, to cope with the evolving technological advancement, researchers have prioritized the issues in the case of cognitive radio that needs to be addressed depending on the domain of operation. The proposed cognitive aeronautical communication systems should also be compliant with the Aeronautical Radio Incorporated (AR-INC) and Aerospace Recommended Practice (ARP) standards. An overview of these standards and the challenges that need immediate attention to make the solution feasible for a largescale operation, along with the future avenues of research is also furnished.

“…One challenge for wireless sensor networks in the aeronautical case is the high density of wireless sensor nodes [2]. The quantity of sensor nodes within an aircraft can easily reach 1000 or more.…”

“…With that many nodes, a typical CSMA protocol ceases to be feasible and a more sophisticated protocol has to be used. In [2] a possible solution is presented; it uses a TDMA protocol with special reliability features. However, this protocol is developed for periodic applications and, therefore, in its present implementation not very well suited for event-triggered applications.…”

In wireless sensor networks (Wsns) energy efficiency and communication reliability are often conflicting requirements. additionally, some application areas such as industrial automation or infrastructure monitoring impose strict latency bounds.Low-power receivers ( mW 1 1 power consumption) together with adapted mac protocols have the potential to meet these diverse requirements. We present an overview of state-of-the-art low-power receivers and relate their characteristics to requirements for different application areas. We compare low-power receivers to duty-cycled transceivers and present applications depending on them. For this, we use power consumption, sensitivity, and data rate as key performance figures for low-power receivers. Based on the characteristics of the applications we derive guidelines for using low-power receivers instead of duty-cycled transceivers. project "AETERNITAS".Johannes Blanckenstein works on communication protocols in the general field of wireless sensor networks and especially on protocols and applications for low-power wake-up receivers. He writes his doctoral thesis at University Paderborn in the computer networks group of Holger Karl. At the same time he works at Airbus Group Innovations in the field of WSN applications for aeronautics.
