Network latency

ETX performs better than OF0 because it considers link level detail

Energy Consumption

Every Consumption of network is more at the start with more lossy network., decrease the lossyness in network the energy consumption. Because the lossy environment has more retransmissions than a lossless environment

LLN has a lossy natute the rank quality changes frequently and there ETX for path also changes frequently. ETX takes into account the path ETX and can reflect the link status more precisely at any time in RPL network

Packet Delivery Ratio

The Packet Delivery Ratio of ETX is better than OF0 in this small sized simulation

Network setup Time with respect to DIO_INTERVAL_MIN

Network convergence

Energy Consumption

For DIO interval minimum, between 5 and 7 energy consumption keeps on descreasing in a linear fashion. The best Energy comsumption can be observed for DIO Interval minimum of 8 and higher.

Latancy

The Latency decrease from 3.5s to 1.7s between 3 and 6s. This sudden decrease is due to to the reason that lower

values DIO gennerated heavy control traffic . Which causes more radio collisions and the packets need to be buffered

which increase overall latency of the packet along the path

Packet Deliver Ration- Which means to high control overhead the RPL network suffer collisions and therefore PDR is Poor.- However as we increase the DIO interval (6-14) RPL provider a good PDR ratio of more 70%.- PDR falls for DIO of 15 and greaser, The reasin is that the value DIO higher than 14 does not provide q quick network convergence

We can observe that ETX provides better latency and PDR using less Energy than OF0
