I have been through the timer code pretty extensively and nothing comes to mind about why it would stop working after around 5 mins. The way the timers work is there is a sync level task called UpdateTimersTask which looks at all active timers and programs the hardware to interrupt in the future. The timer h/w (called an alarm) trips and causes a task to get posted. This task scans the timer list looking for expired timers. Any expired timer is then fired. So what can go wrong. 1) interrupts off? For example on the telosb (or other msp430 varient) there is the GIE bit in the status register. If this is off then the timer h/w can't interrupt. 2) If something is keeping the timer tasks from running. Not very likely. Most everything runs as a task in tinyos and if the timer task was getting posted and the main task loop were running then it is guaranteed that the timer task will run eventually. 3) A task has gone infinite and this prevents any other task from running. 4) the timer in question is not active. Is it a periodic or a oneshot? If a oneshot is it getting rearmed? Basically you will have to dig into the system state at the point of failure and figure out what is going on. It is extremely hard to do that on a mailing list. hope that helps. eric On Thu, Sep 23, 2010 at 9:41 AM, Kartik Siddhabathula wrote: Hi All, Am using tinyos-2.x and telosb motes.

Re: [Tinyos-help] [*] Regarding sending and receiving
Thanks Michael for sharing the report. I know that we do loose messages, in one of my experiment, I did the packet delivery rate test and I found that I lost somewhere between 1 to 11 messages and that is something we are not discussing about as that is acceptable to both me and Harshwal. The reason why I had posted the query in the forum and Harshwal re-posted it is that we wanted to know about the buffer queue size in the receiving end. In one of my experiments, I had one sender and one receiver. Sender transmitted 100 messages continuously through periodic timer fired at 0 ms. I found that in my receiving end I was receiving some where around 30 messages only and that means 70 messages were lost and that's why this thread.

Re: [Tinyos-help] [*] Regarding sending and receiving
Hi Harshal, As from your output it is clear that the receiver mote is able to get the messages. The problem must be in the simultaneous sending. The problem I faced was also when I was sending simultaneously that's why I wanted to know what is the buffer size for receiving. As far as I my understanding goes, the reason must be that when the receiver receives the messages, it keeps in the buffer till it is processed (crc check etc). While it is processing a packet and another one arrives it puts them in the buffer queue.

Your timer one shot of 1000 ms won't fire if your code fails during run-time in

Just check if your successfully sending a packet or not by having a look at the

Hi All, I have disabled the radiobackoff for a mote and it sends continuously i.e. it acts as a jammer. The motes within its range are not able to receive messages from any other motes. The problem is they are able to send out a message. I don't want that to happen either. I want the motes not able to send messages as well. What am I supposed to do?

[Tinyos-help] Need help with Counter Interface
Hi All, I am using the interface Counter to get the time difference between two events. Since the 2nd event lies beyond the limit of the Counter so I have declared a variable which should increment every time there is an overflow. The problem is neither the variable is getting incremented nor the timer is getting reset. As once the Counter gets overflowed it stops ticking again and the value stays at 0 only. In the tutorial it says that the Counter wraps around once it reaches 0 but how to start it again once it reaches 0? Does anyone know how to work with the counter?

Re: [Tinyos-help] how to ensure to send only the preamble and not the message
Hi Eric, Sorry, there seems to be some confusion! Let me phrase my question properly: I want to implement a deceptive jammer. Details of the deceptive jammer are as follows: Deceptive jammer: Instead of sending out random bits, the deceptive jammer constantly injects regular packets to the channel without any gap between sub-sequent packet transmissions. As a result, a normal communicator will be deceived into believing there is a legitimate packet and will be duped to remain in the receive state. For example, in TinyOS, if a preamble is detected, a node remains in the receive mode, regardless of whether that node has a packet to send or not. Hence, even if a node has packets to send, it cannot switch to the send state because a constant stream of incoming packets will be detected. Further, we also observe that it is adequate for the jammer to only send a continuous stream of preamble bits (0xAA in TinyOS) rather than entire packets. I read this in a paper and am curious just like you that how some one can just send a preamble.

Also what preamble are you talking about? The preamble on the radio? the cc2420 preamble? If so you can't do that. My understanding is the radio will start to transmit the preamble if it has something to transmit and after it has done the CCA, clear channel assessment. In other words if there is nothing to transmit it won't transmit the preamble. Catch 22. But maybe you are trying to do something else. In which case, phrasing your question in a more consise, clearer manner would really help you get an answer for the question you are seeking answers to. So what exactly are you trying to do?

(Jammer implementation) To: "Kartik Siddhabathula" Cc: "TinyoS help" Date: Friday, November 27, 2009, 9:04 PM Kartik, I suggest that you take a look at the nesdoc (google tinyos nesdoc) for the platform you are developing for. By looking at the components you currently use to send messages, you can drill-down the wirings until you find the MAC implementation. Learning how to use grep to search contents of files will really help in your search. After you find the file(s) that implement the MAC, you can read its contents to determine where it performs CCA checks prior to transmitting. Hope that helps. I could search myself for your platform and find the files for you, but as the saying goes. "If you give a man a fish, he will have a single meal. If you teach him how to fish, he will eat all his life." Good luck with the search. -Paul Kartik Siddhabathula wrote: Hi All, I want to over ride the MAC protocol.

[Tinyos-help] Writing Failed
Hi All, I am new to the world of TinyOS, and am stuck in the following: I am trying to broadcast and when am trying to do this, my SerialForwarder GUI gives me an error message stating "Writing Failed". Am following the instructions on ch-7 and carried out in the same way, but don't know why I am getting an error. Thanks in advance, Kartik ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
