Techniques are disclosed relating to temporary networks of edge computing devices. In some embodiments, an edge computing device manages, in response to occurrence of an event, a temporary network of edge computing devices. Managing the temporary network includes: forming the temporary network, managing membership of edge computing devices in the temporary network, causing the temporary network to perform a specified set of tasks, transmitting, to a remote server computing system, information associated with the specified set of tasks, and causing disbanding of the temporary network after determining that the specified set of tasks is complete. The disclosed techniques for managing temporary networks of edge computing devices may advantageously reduce the overall use of a network's bandwidth by reducing the amount of communication with a remote server system.
