Packet routing trought rasberry pi

I have implemented mesh network on 5 raspberry pi. I will attach a camera to the 5th node which takes the pictures/video and transfer the captured data to the first node and then to the server.The network protocol is 802.11s.

I have implemented the network using following commands.

sudo iw phy phy0 interface add mesh1 type mp sudo iw dev set channel 10 sudo ifconfig wlan0 down sudo ifconfig mesh1 sudo iw dev mesh1 mesh join biz

This is the script which automatically runs whenever the system restarts. It will create one virtual mesh interface.

All the nodes are in same channel which is 10. All the nodes are in same mesh network which is biz(Mesh Id). IPs are -

In the above diagram 5 node take pictures/video and transfers the data to the available neighbour node and then it transfers to the other available neighbour node. It should choose the best path to transfer the data. Like 5-4-2-1 or 5-4-3-1.

Or if the either of the nodes are unavailable it should redirect the packets to the different node.

For example, in 5-4-2-1 path if node if node 4 is unavailable it should redirect the packets to 5-2-1 if the 2 node is available or should choose the alternative path automatically either 5-4-3-1 or 5-3-1.

So my question is to archive everything from mesh 5 to server and to redirect all package to best way?
