Nodes send packet to one sink?

Hello guys, I have mesh network ( 50 nodes connect to one sink), Can I send packet with 2000-bits to the sink with taking shortest path by codeing. Can you help me please.. I attached my network picture.

Please tell me how did you assign numers to the given nodes?

The node identification numbers can be random, as long as they are unique.

If you have nodes moving into or out of range, or nodes turning on or off, then it would not make sense to identify nodes by position in a matrix, as the position would change as nodes get removed. You might as well assign arbitrary labels instead. In a larger simulation, you would identify nodes primarily by their MAC address as that is how nodes know each other.
