well depends upon the scenario, if you want to deploy routing in network, there might you need to take care of neighborhood nodes traffic patterns. Having information regarding your vicinity neighborhood nodes states, then you can find the best routing path. Node distances could be another parameter. But finding the position in mobile nodes its quite hard to figure out. Friendly speaking there are bunch of others, just google link estimation stuff.
RSSI (Received signal strength indicator) means we can find the measured signal strength(especially in dbm) of the corresponding nodes, if its higher then some threshold you can choose that node for next hope. PRR(packet reception rate) means how much you received out of total which sent by the other node to you. This parameter could be suitable because if you know this statistics you can figure out that your neighbor node have more neighbor nodes who have more interactions thats why the packt loss occurred due to congestion and vice versa. LQI(link quality indicator) is specific parameter which I found in TinyOS. The IEEE 802.15.4 standard defines that this parameter have to use a range from 0 to 255 but a specific formula to calculate the LQI is not defined. For more information google for link quality estimations, you will find buch of stuff.
Friendly speaking I am working on Mobile networks, and I found like dozens of these kind of parameter, which really help to make good decisions for routing. Its all depend upon your requirement. But dealing with large features is overwhelming, and its not easy to deal all of them..
