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
