Hello everybody, We are working on an outdoor WSN application, which should collect data from one or more motes in the field to a single mote connected to a computer. This mote has no power restrictions (powered via USB connection), however the motes in the field do have power restrictions. Currently the power consumption of these motes is rather high since the radio reciever is always on.
Our communication scheme is very simple: after a START command, the field motes start transmitting data at regular interval for a (long) fixed period of time; so after the START command the field motes do not need to receive data from the central mote We already looked into using NetSync or compiling for lowpower, but these mechanisms seem to be rather complex for our approach. Is there an easier way how we can switch off the radio chip between transmissions (on the field motes)? Martin PS: Some extra info: - the mote connected to the PC is running TOSBase and all data is collected using a Java application. - the motes are Tmote Sky, Tmote Mini and Tmote Mini Plus - we use SPReceive and SPSend for communication on the field motes This e-mail and its contents are subject to the DISCLAIMER at http://www.tno.nl/disclaimer/email.html _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
