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.

E2 SO（Energy Efficient Management and Self-Organized Operation in Sensor Networks）项目的总体目标是研究移动的节点之间的无线通信协议选项，并在保持已经紧张的能量预算的同时提高整个通信系统的可靠性。所有的研究都将直接基于第一个资助期的研究结果，以便将预期结果无缝集成到开发的系统架构中。主要目标仍然是提供有效的，即，在非常动态的异构传感器网络中进行能量和资源优化的通信。第二个资助期的研究目标可分为以下几类。首先，移动的节点之间的通信需要设计保持能量预算和硬件约束考虑。计划进一步开发唤醒系统，以便交换节点ID以及完整的遭遇信息。为此，必须区分从地面站发送的信号和从另一个移动的节点发送的信号。以最佳方式，节点ID可以已经被编码在唤醒信号中。为了实现这一目标，必须开发新的自适应协议管理概念。其次，需要在不增加能耗的情况下，提高整个通信系统的鲁棒性和可靠性。一种方法是利用由多个地面站同时接收的来自移动的节点的无线电信号的空间分集。这些信号的组合可以显著提高通信可靠性。其目的是使用地面网络作为一个分布式和动态的多天线系统，需要配置和维护的自组织方式。最后，该系统的可扩展性和可用性是要解决的，特别是对于其他计算机科学项目，以及支持动态适应实验参数的生物学家。将研究协议设计中的新概念，以进一步扩展唤醒系统，使其即使在蝙蝠飞行期间也能将参数变化（几个字节）传达给移动的节点，并支持在其主站进行完整的软件更新（几个字节）。编码算法被认为是提供所需的鲁棒性的更新过程。
