The market forecast for aircraft manufacturers is very promising; the fleet of
passenger aircraft will double. This will clearly generate a strong business
for aircraft manufactures. But new competitors arise and, hence, rivalry is
increasing. To succeed in this market situation, aircraft manufacturers have
to build innovative aircraft to set thems...
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 power consumption) together with adapted MAC protocols have the potential to meet the...
We present the packet error rate (PER) characterization of an aircraft cabin wireless sensor network (WSN). It is based on measurements for a static and a typical dynamic environment, which were both performed in an aircraft cabin mockup. The WSN exploits spatial diversity by using multiple access points, which decreases the average PER by several...
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...
We present the results of a measurement campaign conducted with a wireless sensor network (WSN) deployment inside an aircraft. A robust and scalable TDMAprotocol formission-critical applications was developed, which exploits spatial diversity provided by redundant access points. The WSN, consisting of 500 sensor nodes organized in three cells with...
Intelligent environments (IE) leverage embedded processing and wireless communication to assist users in a variety of ways. Applications rely on low power consumption for longer lifetimes, though different applications require different Quality-of-Service (QoS) requirements from the MAC layer. Until now, low power has come at the cost of other QoS...
We present a new energy-saving method for creating node clusters with similar sensor readings. The idea is to wake up a node/main transceiver only when data correlated to the node's own data is transmitted. This is achieved by encoding relevant parts of local data in a wake-up receiver's data pattern. Through this new protocol the building of clust...
