Dear All,
Does any one know how to use timestamps for packet traversing the network?
Like how can we evaluate the time taken by a packet to travel from source
node to destination node in TOSSIM?
Can we add a field in AM Packet which when we extract at the destination
tells us about the receive
Hello. I need some help.
I would work with MICA2. And my question is the following:
If the base station receives 2 messages at the same time, what are my
possibilities? Can I choose of them? And how?
I don’t know how MICA2 works in such situation.
Thanks!
Tamas
ps. Has somebody done MAC
Hi,
I am searching for the source codes for the following protocols. If any one
knows where to get pls let me know.
i)SPINS
ii)LEDS
iii)LLSP
iv)LiSp
v)SomeSec
vi)SNEP
vii)micro-TESLA
Thanks.
Hi,
I'm experiencing udp checksum error while forwarding packets in
multihop network.
I've modified UDPEcho to get RSSI and LQI in a multihop network using
commands .getRssi() and getLqi() provided by CC2420Packet interface.
I'm testing application in a basic network:
telosb_0 is acting as
All nodes in a system share one radio frequency/channel,
so only one message can be on the air at a time. The
MAC protocol attempts to prevent two nodes from transmitting
at the same time, but if it fails the received result is
usually garbage so sometimes messages are dropped due to
interference.

Doesn't the AMSend interface automatically implement that?

Hi
I am trying to implement replay protection using frame counter. So my plan is
to check the frame counter value of the incoming packet and if it is less than
that of the previous packet then the packet has to be dropped. I am planning to
implement this in CC2420ReceiveP.nc file. However I
Hi
I was going the CC2420ReceiveP code and saw the flush() command to flush the
RXFIFO. It is used when the incoming packet is too large and this command helps
flush the RXFIFO buffer. My question is that is this command flush() equivalent
for dropping unwanted packets?
ThanksAniket
Hi,
I am using the most lowest component for sending i.e CC2420transmitC, and
CC2420ReceiveC.
Problem is that it is taking too long to send and receive a message with
just 2 bytes payload and 21byte header (CC2420_SIZE).
It is taking 8ms, so if a sender has send a packet, ACK will be received
Hello,
I have a question about AVcc, my sensor use analog input 3 (ADC3) to give
voltage.
so how can i fix the Oscilloscope profile to give voltage for my sensor.
Thanks.
