Hi, i am a beginner of tinyOS , currently i am working on a WSN project ..The purpose is to track a target inside the network. We will have two anchors ( MICAZs positions are already know) two relay node and one base. My questions is
1) How to send the information (hop count) from the anchor that i received from the target to the base station( via multi-hop ) ...if i put the station close to one anchor the then the other anchor will be out of range thanks for the time and really appriciate it , lance On Fri, Oct 1, 2010 at 3:00 AM, <[email protected] > wrote: > Send Tinyos-help mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > > https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help > > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Tinyos-help digest..." > > > Today's Topics: > > 1.
