Wireless device link metric for effective comparison of multi-hop routes in wireless mesh networks

摘要

WIRELESS DEVICE LINK METRIC FOR EFFECTIVE COMPARISON OF MULTI-HOP ROUTES IN WIRELESS MESH NETWORKS Link metrics for communication paths in multi-hop wireless mesh networks of industrial radio device (100) are determined based on signal strength and traffic level performance of each link in the communication paths. A path metric is determined from the link metrics and path metrics are compared and utilized for optimal routing of messages through the network. 71filA 1 Power Supply 118 Radio 1n102 pP Memory 104 116 Control Device Transmitter Receiver 108) 110 scADA System 112 156 156 120 1ontro FCntr154 154 A Commi1 D 154 G Comm 2 j s Comm 1 Comm 2 Comm 3 Sensor 1Sensor 2 Sensor 3 Control LControl 156 Comm 3 LComm 4 15 6 Control O Comm 5 Gateway 124 Control Center 126
