Description

1. Phase

In the scope of the DFG research group BATS (Dynamically Adaptable Applications for Bats Tracking by Embedded Communicating Systems), the project E2SO focuses on challenges related to the efficient communication with integrated self-organizing data management in highly dynamic sensor networks. The communication primitives to be developed primarily target the operation with limited energy and other systems resources. In particular, three aspects will be investigated in this research project: First, the sensor nodes developed in BATS will be extremely challenging in terms of energy (the system design expects a node weighting of 2g including the battery). Therefore, new communication techniques are needed for connecting the mobile nodes to the stationary ground network. Our partners from electrical engineering are about to develop mobile sensor nodes as well as the ground network systems. Besides of the limited computing and storage resources, the limited connectivity of the mobile bats constitutes new challenges that can only be investigated in this interdisciplinary team of researchers. A second focus is on the temporal storage of dynamically generated information and on the efficient access to these data. The concept is to use DHT concepts for maintaining measurement data that will be processed in the network relying on data stream processing techniques to finally be used for answering questions in the field of biological behavioral research. The third research aspect of the E2SO project is to provide continuous resource and topology monitoring in order to extend the network lifetime as a key metric describing the overall system performance and to early detect bottlenecks that can be mitigated using online reconfigurations of the data streams.

E2SO Architecture

2. Phase

The overall objective of the project E2SO (Energy Efficient Management and Self-organized Operation in Sensor Networks) is to research wireless communication protocol options between the mobile nodes and to improve the reliability of the entire communication system while maintaining the already tight energy budget. All the investigations will be directly based on the research results from the first funding period in order to seamlessly integrate expected results into the developed system architecture. The dominating objective is still to provide efficient, i.e., energy and resource optimized communication in very dynamic heterogeneous sensor networks. The research goals of the second funding period can be categorized as follows. First, the communication among the mobile nodes needs to be designed keeping the energy budget and the hardware constraints into account. It is planned to further develop the wake-up system in order to exchange node IDs as well as complete encounter information. For this, the signal sent from the ground station and that from another mobile node must be distinguished. In the best way, the node ID can already be encoded in the wake-up signal. In order to achieve this, novel concepts for adaptive protocol management have to be developed. Secondly, the robustness and reliability of the entire communication system needs to be improved without increasing the energy consumption. One approach is to exploit the spatial diversity of the radio signals from the mobile nodes that are received by multiple ground stations simultaneously. The combination of these signals may substantially improve the communication reliability. The aim is to use the ground network as a distributed and dynamic multi antenna system that needs to be configured and maintained in a self-organizing manner. Finally, scalability and usability of the system is to be addressed, particularly for the other computer science projects as well as for supporting the dynamic adaptation of experiment parameters by the biologists. Novel concepts in protocol design will be researched to further extend the wake-up system to also communicate parameter changes (a few byte) to the mobile nodes even during the bat flight as well as to support complete software updates (a few kilobyte) at their home station. Coding algorithms are considered to provide the required robustness of the update procedure.
