Figure 15From: Impact of LQI-Based Routing Metrics on the Performance of a One-to-One Routing Protocol for IEEE 802.15.4 Multihop NetworksExample of route selection based on LETX and ZigBee metrics, whereby PDR grows as the distance between sender and receiver grows. The number placed next to a link indicates the LDR of that link. The shaded boxes indicate the cost of the path selected by each routing metric between node A and nodes D and F.Back to article page
