由许多传感器单元组成的自主传感器网络（ASN）被提出并研究，作为开放环境实验中人工生命的新挑战。这项研究的目的是调查人工生命系统在真实、开放、不断变化的环境中如何表现，包括人类行为在内的短期和长期环境变化。与开放空间中的机器人实验相比，我们说ASN不会在空间中移动，而是可以进行更长时间的测试，具有很强的自主行为，而不会忽视环境的杂乱性。传感器网络是独一无二的，因为我们采用人工化学来使其能够控制每个传感器单元的灵敏度（即传感器不仅仅是对环境变化做出反应，而是相互影响）。根据环境模式和传感器之间的交互条件，系统在谐振状态和静止状态之间切换。静止状态是正常环境条件下网络的基线活动，当环境参数（即光照条件）发生变化时，就会出现共振状态。我们通过模拟器测试了这种行为的本质，显示了从静止状态到谐振状态的采样周期的转变点。为了“体验”这种静止状态和共振状态之间的切换行为，我们通过使用单向超声波扬声器将传感器状态转换为声音模式来组织声音装置。这样的艺术装置可以成为测试现实世界中人工生命的长期适应行为的好机会。
An autonomous sensor network (ASN), which is composed of many sensor units, is proposed and studied as a new challenge for artificial life in open-environment experiments. An aim of this study is to investigate how an artificial life system behaves in a real, open, ever-changing environment with short- and long-term environmental changes, including human behaviors. Compared to robot experiments in an open space, we say that ASN will not move around in a space but can be tested for a longer period of time with strongly autonomous behavior, without ignoring the messiness of the environment,. The sensor network is unique because we employ artificial chemistry to enable it to control the sensitivity of each sensor unit (i.e., sensors are not simply reacting to environmental changes but are mutually affecting each other). Depending on the environmental pattern and interaction conditions between sensors, the system switches between a resonating state and a resting state. The resting state is the baseline activity of the network for a normal environmental condition, and the resonating state emerges when the environmental parameter (i.e., the light condition) changes. We tested the nature of this behavior by an emulator, showing the transition point in its sampling periodicity from a resting state to a resonating state. To “experience” this switching behavior between a resting and resonating state, we organized a sound installation by translating the sensor states into sound patterns with unidirectional ultrasonic speakers. Such art installation can be a good opportunity to test long-term adaptive behaviors of artificial life in the real world.
