Jan Drees, "Evaluation of Selective Wake-up Receivers (SWuRx) For Routing In Wireless Sensor Networks," Bachelor Thesis, Department of Computer Science, Paderborn University, December 2017. (Advisors: Johannes Blobel and Falko Dressler)


There are numerous possible applications for wireless sensor networks (WSNs) and new ones emerge continuously, such as the internet of things. Since radio communication makes up the biggest portion of a WSN devices power consumption, reducing it will increase the lifetime of a WSN dramatically. The selective wake-up receiver (SWuRx) aims to reduce idle listening of the radio receiver by adding an ultra-low power receiver to the node. The WSN device can remain powered down until the SWuRx receives a wake-up signal containing an energy burst as well as his address. However, the effect of using a common routing protocol in combination with the SWuRx has not been examined. In this thesis, I evaluate the SWuRx using simulations of abstract WSN scenarios utilizing ad-hoc on-demand distance vector (AODV) routing. The impact of the SWuRx on reliability, latency and power consumption is compared to the wake-up receiver (WuRx), X-MAC and regular always-on operation. I also propose a WuRx media access control (MAC) protocol that improves reliability significantly by using retransmissions. I find that the WuRx reduces radio energy consumption by two orders of magnitude while still providing an acceptable reliability for low network loads. The SWuRx saves a little more energy but also decreases reliability. A few bits of SWuRx addressing are enough to attain this reduced power consumption. The SWuRx can therefore be employed in combination with AODV routing to increase network lifetime. The results also indicate that improving WuRx MAC protocols is necessary.
