摘要

A wireless communication system includes a number of devices to be clustered for the exchange of data and control message packets. Each node (ON, IN1 to IN5) has a unique address within the cluster and is arranged to accept only messages transmitted to it. A dynamic re-routing technique is provided whereby a message packet (M) not received by its target node is detected and re-routed via one or a succession of other nodes of the cluster until either transmission is successful or a predetermined number of failed attempts has been made. The system provides distributed control and intelligence with intermediate nodes for re-routing being selected randomly and current count values for unsuccessful transmission attempts being included within the transmitted packet.
