1. I have placed 6 nodes in the following way. 2 4 5 1 3 6 Node 1 broadcasts a packet. If I keep the distance among them less, the message reaches to each node directly from 1. If not, then 4, 5 and 6 do not get. Is there any way by which the packet can be made to travel like from 1 to 2, 2 to 4, 4 to 5 likewise? 2. I get error like Segmentation fault (core dumped) Dhara Buch
