Abstract—The rapid development of wireless technologies, such as Bluetooth, IEEE 802.11 and IEEE 802.15.4 protocol has allowed the deployment of wireless sensor networks with thousands of sensor devices in physical environments where the construction of a fixed infrastructure is inconvenient or impossible. System designers have been facing the challenges of using unreliable wireless channels and limited battery power to develop software and protocols for sensor networks. This work focuses on the issues of robustness and efficiency in the design and implementation of wireless sensor networks using Sun SPOTs device. Our implementations not only allow multiple sensor nodes to simultaneously connect to the basestation, but also improve the robustness by handling loss of connection (due to node movements or radio interference). To support flexible and efficient data collection, a sensor collects data during disconnected status, and automatically uploads the stored data when it is in the range of a basestation. The testbed is useful for researches on human mobility pattern, environmental monitoring, and health care, to name a few.
