To get an idea about how routing protocols are implemented, you should
look at MultihopLQI (tos/lib/net/lqi). In LqiRoutingEngineP.nc you
will see a function called RouteSelect.selectRoute which is called by
the forwarder before forwarding the packets. You can put your static
routing table somewhere there. Once you determine what the next hop
should be, you can change this line at the end of that function:
call AMPacket.setDestination(msg, gbCurrentParent);
