Hi,
I am trying to connect rpl native border router to simulated sky motes., using slip radio and serial socket
when i start the simulation the DIO packet sent by border are getting DIO ACK from nodes, but data packets send by nodes are not reaching to border router.
Though nodes sending DAO packets for DIO from border router, border router still sending many DIO packtes
I can see the packets received over slip radio on terminal, but in border-router.c I added lines to listen the tcpip event
while(1) {
PROCESS_YIELD();
if(ev == tcpip_event)
tcpip_handler();
}
that event is never triggered during simulation, though continuous data packets are sent form other nodes
I have working code of this, It is working fine on sky platform (sink and other nodes are sky motes )
I tried cooja mote as sink node, RPL tree is getting constructed, for every DIO from cooja mote there is DIO ACK repled from other motes, but still cooja mote sending continuously DIO packets. here also same case as with border router
I am not able to understand what is wrong going here ?
I tried all possible combination by changing MAC & RDC layer protocol through conf files, but still no success
please need a help to solve this
any one succeeded in this
Thanks
Once you have added nodes, you may want to check if they can communicate
with each other. From the Network window, left-click on the View textbox
5
and tick Radio Environment (UDGM) in the text window that pops up. If
you now left-click on one of the nodes, you will see a green circle around the
selected node. The green circle presents the transmission range of the node,
i.e. the selected node can communicate with all other nodes within that circle.
You may also see a grey circle around the green circle. This circle represents
the interference range. That is when the selected nodes transmits packets,
a node in the grey area cannot receive packets correctly but it is interferred
which means that it is not able to receive packets from other nodes when the
selected node communicates simultaneously. The areas that are not covered by
the green or grey circle are white; communication in that areas is not affected
at all by transmission from the selected nodes.
