Lower-layers have a major impact on upper-layer performance, and the complexity of the phenomena can not be entirely captured by analysis or simulation. In this report, we go through the complete process, from designing an energy-efficient self-organizing communication architecture (MAC, routing and application layers) to real-life experimentation roll-outs. The presented communication architecture includes a MAC protocol which avoids building and maintaining neighborhood tables, and a geographically-inspired routing protocol over virtual coordinates. The application consists of a mobile sink interrogating a wireless sensor network based on the requests issued by a disconnected base station. After the design process of this architecture, we verify it functions correctly by simulation, and we perform a temporal verification. This study is needed to calculate the maximum speed the mobile sink can take. We detail the implementation, and the results of the off-site experimentation (energy consumption at PHY layer, collision probability at MAC layer, and routing). Finally, we report on the real-world deployment where we have mounted the mobile sink node on a radio-controlled airplane. %G English %2 https://inria.hal.science/inria-00263534v2/document %2 https://inria.hal.science/inria-00263534v2/file/RR-6471.pdf %L inria-00263534 %U https://inria.hal.science/inria-00263534 %~ INRIA %~ INSA-LYON %~ INRIA-RHA %~ INRIA-RRRT %~ INRIA_TEST %~ TESTALAIN1 %~ INRIA2 %~ LARA %~ INRIA-RENGRE %~ CITI %~ INSA-GROUPE %~ UDL
