I suggest trying XMesh apps distributed with MoteView instead.
http://www.xbow.com/Support/wSoftwareDownloads.aspx

These are couple of generations better than the surge_reliable that you
are trying to use. The MoteConfig utility that you would use to program
these apps, lets you tune the radio transmit power as well. Please refer
to MoteConfig user's manual for further details.

Subject: [Tinyos-help] An issue with Surge Reliable

I wish all the members a very happy new year 2007.

I have programmed Surge_reliable from contrib/xbow/apps on four number
of micaz motes.
When I run the java application net.tinyos.surge.MainClass, I could see
all the four nodes in the topology view.

I noticed that all the nodes are directly reaching the base station. I
was trying to test the multi hop behaviour and so moved away one of the
node, but that node could not reach the base station using intermediate
nodes. I have programmed the base node with TOSBase application. Am I
doing anything wrong here?

When I used raw listen, I noticed that the headers of the received
packets indicate broadcast address (ffff) rather than the address of the
forwarding node. What could be wrong here?

Another issue is that how do I reduce the transmit power of the
nodes(micaz) so that I can test multihop routing in a small work space
such as inside the lab environment?

I would appreciate help from the experts.
