Hi I want a node to send packets to all other nodes within its radio range. What is that I have to put in the common header?? Will a MAC_BROADCAST do the above function? I did cmh->next_hop_ = MAC_BROADCAST and cmh->addr_type_ = NS_AF_INET If I do only the following I get a error _o29 no target for slot 0 Then what should I put in the ip header. Remember I should not do a ip broadcast. Thank You Madhan
