connecting 2 hosts with uIP

Hello,

 

Is it possible to connect 2 hosts ("H"s on the image) with uIP stack.

According to the image (extract from the book 6LoWPAN : the wireless embedded internet, from authors Zach Shelby and Carsten Bormann) such connection requires 3rd protagonist – Router (encircled "R"s inside of Ad-Hoc LoWPAN).

Am I correct ?

 

Cordially

 

Pavel

ACM Sensys 2014 Doctoral Colloquium

Apologies if you receive multiple copies of this email.

===================================================
S E N S Y S   D O C T O R A L   C O L L O Q U I U M 

**** Collocated with ACM SenSys 2014 ****
Memphis, TN, USA
November 6, 2014
http://sensys.acm.org/2014/dc

====================================================

The Doctoral Colloquium (DC) of SenSys 2014 seeks to provide a friendly, supportive, and constructive
environment where PhD students can present their research in progress for an open discussion guided by a
panel of experienced researchers and practitioners.

The DC will be structured as a series of short presentations by the students followed by individual
discussions, feedback, and advise. The student presentations will be interleaved with speeches by
leading researchers, who will provide their own perspectives on current and future research trends in
networked sensing, as well as on how to best purse a Ph.D. in this field. Participating students will also
have the opportunity to present a poster during the main conference to leverage further interaction with
SenSys attendees.

Current Ph.D. students in the early stages of their career are encouraged to submit a 2-page extended
abstract about their dissertation research to be considered for the DC. The abstract shall also include a
one-paragraph bio of the student, along with information on how long he/she has been in Ph.D. school and
the expected time until graduation. The student should be the sole author, although contributions of the
advisor and others should be acknowledged. The DC committee will review submissions to ensure quality,
relevance, and potential benefit from attendance. Authors of accepted submissions are expected to
participate in person to the DC - to be held on November 6th, 2014 - and to present a poster at the main
conference. There will be no separate registration fee for the DC.

============================================
Submission Guidelines
============================================

Submissions must be received no later than September 2nd, 2014 via http://submit.ece.cmu.edu/sensysDC/

Submissions must be in PDF format, be written in English, of no more than two pages in length (all
inclusive), and adhere to the SenSys formatting guidelines http://sensys.acm.org/2014/cfp/. The

Telnet server for 128rfa1 board...

Hello,

I have been successfully able to run examples/ipv6/simple-udp-rpl/ unicast-sender/receiver using 128rfa1 boards. Message from the sender reaches the receiver and also the neighbor and routing information is available on rzuxb stick connected on a laptop. I am able to ping each node from the laptop. The rzusb (as jackdaw) shows the following :

Addresses [4 max]                                                              
bbbb::12:13ff:fe14:1516                                                        
bbbb::200                                                                      
fe80::12:13ff:fe14:1516                                                        
                                                                               
Neighbors [2 max]                                                              
fe80::13:13ff:fe14:1516                                                        
fe80::14:13ff:fe14:1516                                                        
                                                                               
Routes [2 max]                                                                 
bbbb::13:13ff:fe14:1516/128 (via fe80::13:13ff:fe14:1516)                      
bbbb::14:13ff:fe14:1516/128 (via fe80::14:13ff:fe14:1516)                      

Now I want to telnet on the motes from the laptop. Has anyone compiled and tested it for 128rfa1 for ipv6 ?

Regards,

P Gupta

/ tools / collect-view

My network architecture consists of three node: one on which I put rpl-border-router and the other two node rpl-udp, the connection is between the node establishes 
i use Serial Socket (SERVER) "to Creates 
a serial Port on the simulated node 1 Which is accessible via UDP port number 
60001 on the local machine. 
but my question is how can I view the metric, power, traffic, latency .. 
I used the / tools / collect-view but nothing happened again how can I solve it

Hi,

If you want to use unicast transceiver, you can check exemple in
/examples/ipv6/simple-udp-rpl/unicast-sender receiver.

If you want to use this exemple, you first need to register an IP adress in
the servreg-hack apps from Contiki (see unicast-receiver.c), then flash the
unicast-sender.c who gets the receiver Ip adress from servreg-hack and
sends message to that IP adress.

In the unicast-sender exemple, the function set_global_adress is used to
set the adress of the node. Then this address in store in servreg-hack, by
linking a Ip address to an ID service of servreg.

the sender get the address of the receiver at line : addr :
servreg_hack_lookup(SERVICE_ID)

RPL - use of flow label or 6lo or HbH


The IETF 6man, ROLL (and at the last minute, 6lo) working groups are
considering whether to permit InstanceID and rank of regular data flows,
currently carried in a Hop-By-Hop header could be replaced by using the flow
label, or alternatively, a new 6lo HC mechanism to store the same data has been proposed.

Contiki implements thhe HbH option in core/net/rpl/rpl-ext-header.c

The motivation for this work is a savings of 5% in packet size.

Your comments to the roll@... and 6man@...
would be helpful.

Er-example with client

Hello Guys,
                 I have been trying to get Er-rest example working but it doesn't work.
I am running  server-only.csc and connecting with make connect-router-cooja command it works fine, when i am trying to access the resource through copper plugin it works fine too, but when i am trying to access server using client running natively its not working, so i have stores all the radio messages in a pcap file and then analyse it with wireshark , there one thing i observed that  there is no coap message type is there all the ipv6 type message. so i thing that coap-request is not able to hit server or server rejecting it.
I am attaching pcap file containing radio messages.

Thanks in advance

Re: validation of COOJA radio models

Hi All,

 

Now that more people have come back from vacations, just wanted to ask my question again.

 

I was wondering if any of you knew of papers or theses which have done a validation of any of the radio models that were implemented in COOJA? I was trying to find work which has done some tests indoors or outdoors, in a real testbed, and has compared the results to the ones given for the same setup in COOJA. The only work I have found was “Radio propagation in industrial wireless sensor network environments: from testbed to simulation evaluation" by Zinonos et al. (http://dl.acm.org/citation.cfm?id=2387209) which validates their tailored model in COOJA to the real radio statistics in a refinery. Any other model validations performed in COOJA, particularly the ones already provided, have been made?


Thanks for the help!

 

Best regards,

Jose Araujo

Hi Mohammad,

 

That’s great news! Whenever you have the results published (report, thesis or paper) just let me know! In case you have seen any paper with validation results for that or other models please let me know as well. Thanks!

 

Best,

Jose

from my experience, the mrm model seems to give similar results to real world in an open door experiment with no obstacles.

i am currently doing some test with obstacles and will see if it compares with the mrm with obstacles simulation.

create a new type of mote in contiki

Hi everybody,

My project consists of adding a new mote created by me, simulate its functionnalities like measering temperature and humidity, configure it ...etc. I have an idea about using cintiki and simulate some protocols.

 But now my problem is that i don't know how can add this new mote in contiki.

I will be grateful if someone answer me or send me a helpful link to help me and clarify.

Cordially.

flash read/write with cc2538

Hi developers,

My projects require rom/flash to be used for data storage. I can read/write flash variable, and need a flexible way to access instead of pointing out address directly, e.g flash_read(address), flash_write(address, value).

Come from avr, I should say avr gcc have good lib to work with rom: with uint16_t EEMEM abc; declaration, gcc will allocate a place at ROM. 

Could we have this feature for cc2538? Or any good way to access flash for cc2538.

Thanks for reading this email. Any comment is more than welcome.
