in light.c, there is the notion of firstPacketSent. This is not needed as we know the LED is OFF to start with

The FAKESEND idea can only be used if we receive a packet with the same state that we have now and the last packet was received a long time ago.
How it is implemented now we may get a transition before it happens. The 2s is the minimum interval in between transitions, but the transitions may take a long time, more than 2s.
So, if we get a packet with the same state and our last packet was more than 4 seconds ago, it means we missed one transition. This assumes our packets will not be traveling on the network for more than 4 seconds, which is OK to assume.

If we receive a beacon from a node with small rank we switch right aways, We should only switch the parent if the rank is lower AND we received more beacons than what we received from our current parent.

I suggest 11, 15, 20, 26

If I receive or generate a packet with seqnum==15, I should drop all the packets in the queue which are older than thay seqnum

reduce the time the mote spends blinking the CRITICAL led to 100ms

packets will not exceed the EB/DATA packet formats. Tune so that the slot length is the shortest possible.

hace beacon carry app state. parse beacon

put maxfor node in our testbed

Hey @pedrohenriquegomes Pedro Henrique Gomes,

Is this intended to me? I am (bhaskar2), I have received notification that you have added access to this repo.

with 14 neighbors, the probability of having exactly one mote transmit in a cell is lowest when each node transmits with 1/14 probability, assuming all nodes have something to send. Apply that rule to transmitting data.

data packets should be as short as possible

• read
  • DS2411
  • flash memory
• print over serial in ASCII

Every time the sink receives a DATA packet that is more than 4 seconds ahead of the last packet, and the state is the same, it toggles the output to signalize the transition

Have the first slot be for EB. In that slot, each mote either transmit (1/15 probability) or receives. EBs are hence not sent based on a timer.
