Abstract

Energy efficiency in Wireless Sensor Networks (WSNs) is a very important factor, because the nodes, that are part of these networks are powered by a battery in most cases. Furthermore it is not possible or efficient to change the batteries of those nodes in many scenarios, because they are deployed in inaccessible areas. One approach to decrease the power consumption of these WSNs nodes, is to use duty cycling, where the node has sleeping phases and active phases, which requires the nodes to be synchronized, in order to communicate with each other during the active phases. Wake-up Receivers (WuRxs), as part of the node, help to eliminate the overhead used for synchronization, as they are turned on the whole time and wait for incoming wake-up messages, upon which they would wake up their node. An advancement of the WuRx is the Selective Wake-up Receiver (SWuRx), which allows the transmitter to decide whether it wants to send a unicast, multicast or broadcast wake-up message, by adding a mask and an address to the wake-up message. A hardware prototype of the SWuRx is evaluated in this thesis. Therefore a measurement environment and tools have been developed during this thesis, in order to conduct a number of experiments with the hardware prototype. Based on the measurements achieved in these experiments, a model of the SWuRx was also implemented in an OMNeT++ simulation and its correctness has been evaluated with a number of simulations. During these simulations the SWuRx performed as expected and was working correctly. However problems regarding false wake-ups, of which a few of them were already resolved, occurred during the experiments and have to be solved in future work.
