[Tinyos-help] How to change the channel frequency of TelosB mote dynamically?

2013-06-11 Thread Han Bin
Dear everyone,

I'm currently working on TelosB motes using TinyOS 2.1.
Could you please show me how to change the channel frequency of Telosb mote
dynamically (without using the MAKEFILE). 
For example, during the operating time, we can use a command/function to
change the frequency of motes, depending on the environment conditions, etc.

Any help or suggestion will be appreciated.
Thank you very much!

Han Bin.

[Tinyos-help] CfP: Int. Workshop on Real-world Wireless Sensor Networks - Submission approaching!

2013-06-11 Thread Mikhail Afanasov
Call for Papers: The Fifth Workshop on Real-World Wireless Sensor Networks
==

19-20 September 2013
 Como Lake (Italy)
   http://realwsn.deib.polimi.it
 Follow REALWSN on Twitter: @RealWSN!

We are excited to announce that the fifth Workshop on Real-World
Wireless Sensor will be held at the Como Lake, Italy in September 2013.

The purpose of the fifth Workshop on Real-World Wireless Sensor
Networks (REALWSN) is to bring together researchers and practitioners
working in the area of sensor networks, with focus on real-world
experiments or deployments. Included are, nontheless, new forms
of sensing such as those that leverage smart phones, Internet of
Things, RFIDs, and robots.

When working with real-world experiments or deployments, many new
issues arise: the network environment may be composed of a variety of
different technologies, leading to very heterogeneous network
structures; software development for large scale networks poses new
types of problems; prototype networks may differ significantly from
the deployed system; actual sensor network deployments may need a
complex combination of autonomous and manual
configuration. Furthermore, results obtained through simulation are
typically not directly applicable to operational networks and it is
therefore imperative for the community to produce results from
experimental research.

Authors are invited to submit papers (12 pages, Springer format, 10
point font size) for presentation at the workshop. Papers will be
selected based on originality, technical merit, and
relevance. Submissions must be fully anonimized, as REALWSN will apply
a double-blind review process. Accepted papers will be published by
Springer in the Lecture Notes on Electrical Engineering series and
indexed by all major digital libraries (e.g., ISI, Scopus, Google
Scholar, ...).

All topics pertaining to real-world wireless sensor networks and modern
forms of sensing are of interest, including but not limited to:
* Experiences with real-world deployments
* Mining real-world sensor network data
* Sensor systems leveraging smart phones (crowd sensing)
* Sensors systems involving Internet of Things (IoT), RFIDs, robots
* Experimental validation/refutation of previous simulation
  results obtained by others
* Real-world performance of self-organization and self-management
* Debugging, testing, validation, and management
* Deployment and configuration
* Applications in medicine, industry, science, environmental monitoring
* Security and trust
* Scalability in practice
* Development and prototyping platforms
* Operating systems, sensor network programming paradigms, and languages
* Middleware for heterogeneous networks
* Real-time and dependability issues
* Hardware support for real-world sensor networks
* Robustness at all levels: communication, software, hardware
* Energy efficient protocols
* Hardware and software methods for energy measurement and profiling

Important dates:
* Electronic submissions due: June 21st, 2013
* Notification of acceptance: August 8th, 2013
* Camera-ready copy due: August 30th, 2013
* Workshop: 19-20 September 2013

We will organize a poster and demo session as well. The deadline will
be August 15th 2013, notification August 22nd 2013. A separate call
will be distributed.

Workshop Chair:
* Luca Mottola, Politecnico di Milano, Italy and SICS, Sweden

Hi Han
TelosB uses the CC2420 radio transceiver, whose libraries are located at 
/tos/chips/CC2420 
(https://github.com/tinyos/tinyos-main/tree/master/tos/chips/cc2420). The 
component CC2420ControlC may help you 
(https://github.com/tinyos/tinyos-main/tree/master/tos/chips/cc2420/control). 
If you are working with the TKN 154 implementation, then, you are using the 
IEEE 802.15.4 MAC and PHY layers instead the TinyOS native ones. In this case, 
make use of the primitive PLME_SET_request.
Regards
David

Hi David,

Thank you for your reply.
I can do it now. We can use CC2420Config interface (setChannel() command) to
set channel number for motes.
I'm working on designing a MAC protocol for WSN. In my protocol, mote is
required to change channel during operating time. 
Thank you very much!

Best regards,
Han Bin.

[Tinyos-help] Real ADC values from SHT11 sensor on TelosB

2013-06-11 Thread Sean Dekker
Hi all,

Can someone please tell me what is the range of RAW data from the temparature 
sensor on TelosB? I was thinking it should be 0-4096 but I am getting values 
like 6553 or so...Am I doing something wrong?

Also, for the conversion formula...is the conversion formula different when the 
TelosB is powered via USB compared when its powered by AA batteries?


Regards,
Sean.
