WIRELESS NETWORKED MESSAGE ROUTING |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To solve the problem that a packet may not directly be transmitted between nodes. <P>SOLUTION: 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 the relevant node. 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. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
