The process of bypassing radio dead-spots in Z wave is done using a message called healing

Z wave is a protocol for communication among devices used for home automation. The Z wave binding supports features to heal the network if nodes become unresponsive. A node is considered dead if it does not respond to a request after three tries. A notification is sent to start a network heal on the dead node. When the node responds it is marked as alive and its retry privileges are restored.
