Cross-Layer Routing Metric for Wireless Mesh Networks

To meet the shortage of the typically routing metrics used in wireless mesh network, this paper proposed a new routing metric for wireless mesh network—CAETT (Congestion Avoidance Expected Transmission Time), comparing with several other routing metrics. With the queue’s utilization rate and the transmit situation of control frames in 802.11 protocol’s MAC layer, a reasonable path is chosen in terms of the channel competition status, link data frame delivery rate and the node’s queue utilization rate. After that the advantages of this new routing metric and its applications were discussed. Finally the simulation experiments show the good network performance.
