[Tinyos-help] An issue with Surge Reliable

[selvaraj]

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.
