Routing is based on the location of the nodes not on the ETX. The model is implemented over ContikiOS RPL with hierarchy based location address

• collect-common.h - support file to sink and sender
• collect-common.c - support file to sink and sender
• udp-sink.c - sink code
• udp-sender.c - sender code
• rpl-dag.c - best and preferred parent selection is modified
• uip6.c - forwarding packet is taken care
• patch.sh - run the patch in the contiki folder to run the model

To run and execute the above model, do the following:

1. Run the patch in the contiki folder
2. change the #define SCENARIO in the collect-common.h to 1 or 0 based on your application requirement
3. If you intend to use more number of nodes, increase the #define NUM_NODES, default is 12
4. Also the nodes are assumend to be hierarchy and continuous in addressing thus make sure you change the #define FIRST_NODEID
5. Run cooja and follow the report (IEEE paper submission) or presentation.
