Abstract

Wireless Sensor Networks consist of autonomous nodes which gather environmental data and send it for further processing to a sink. Therefore, it is not necessary to connect one single dedicated computer with sensors via cables. Equipping animals with nodes for wildlife monitoring is one possible use-case. They are able to measure the body temperature and locate the actual position of the animal. WSNs have been already successful within projects to monitor wildlife behavior of zebras and rats. But for smaller animals it is necessary to create smaller devices with reduced weights. In particular, the BATS project is interested in social behavior of bats. Due to their weight of 30 g they are not able to carry sensors heavier than 2 g. Thus, the battery weighs 1 g and suffers under a low capacity. The demand for power efficient technologies is high in order to increase the overall sensor network lifetime. The usage of a radio module has a significant impact on the battery lifetime. Transmitting data when the communication partner is not able to receive the message results in wasted energy. Therefore, it is necessary to develop highly energy efficient protocols. This thesis gives an overview about existing low-power communication approaches and describes why they are not applicable to the BATS project. Three power saving protocols are specified which are applicable to the used Multi-Stage Wakeup Receivers. They are evaluated within a discrete event simulation framework and compared by the inter-arrival time of received messages. As a result, a Time Division Multiple Access (TDMA) based protocol with fixed ids offers a constant inter-arrival time which is affected solely by the frequency of sent wakeup signals.
