Hi everyone, I have a simulation with 20 nodes(one sink and 19 senders, maximum 5 hops) using apps/tests/TestRPL, each sender sends one udp packet every second to the sink, I found nearly half of the udp packets lost.
Some packets are lost due to collision (drop after several retransmission), part of them lost after received ACK, the rest lost packets even did not shown up in the wireshark. So what can be the reason for the packets lost after received ACK, and the packets did not show up in the wireshark and how to solve the problems? Thanks in advance! Best Wishes! Lixia
