[Tinyos-help] variation of duty-cycle in Low Power Listening while sensing

2010-08-31 Thread Davide Pusceddu @ CIT
Hi, I've developed an application for Micaz using the blip stack and low power listening LPL is configured as follow sleep interval =1024 delay = 2048 retries = 2 I've probed and measured Amperes used by motes while working in single hop and I can see two different values for duty-cycle: When

[Tinyos-help] Routing protocol

2010-11-03 Thread Davide Pusceddu @ CIT
Hi all, I've recently installed tinyos-2.1.1 and I'm testing the blip stack on telosb and iris using IPBaseStation and UDPEcho applications. I've few questions: What is the routing protocol implemented in Blip? Where I can find detailed documentation about the implementation of the routing

[Tinyos-help] CdSe photocell lux

2010-11-19 Thread Davide Pusceddu @ CIT
Hi, I'm collecting light data using MDA100 and MTS300 sensor boards on IRIS. Both boards have CdSe photocell (max at 690nm). As far as I know there is no formula to convert the ADC value to lux and I'm wondering if somebody of you have a look up table to match ADC value with lux. I want to c

[Tinyos-help] sendDone_task in CC2420Csma

2010-12-06 Thread Davide Pusceddu @ CIT
Hi, I've noticed that sometimes, depending on the total number of tasks, the cc2420 takes too much time to stop. For example, when no signal is on the radio it usually takes 8 msec but sometimes it takes 100 msec. We have tried to "help" the cc2420... in the async event CC2420Transim.sendDon

[Tinyos-help] radiochip status

2011-04-18 Thread Davide Pusceddu @ CIT
Hello, I am using low power listening and the blip stack on CC2420 (TelosB) and I'm trying to measure how long the radiochip stays in OFF, Sleep, Idle, RX and TX mode. The target is to understand how much the density of the network influence the power consumption due to the radiochip usag
