Abstract: According to the requirement for adaptability in distributed embedded system such as UAVs, wireless sensor network and so on, some common methods are proposed to define similar nodes, compute their similarity degree, discover similar nodes and deploy the other’s tasks on them automatically. Based on the adaptive computing thoughts of “sensing  evaluating  adjusting  sensing”, some reconfiguration ways for fault nodes and tasks are studied. The methods are more efficient to improve the adaptability of distributed embedded systems, in which some nodes are similar.

Key words: embedded distributed system, similar node, adaptive, deployment, reconfiguration
