Hi bt users

I am doing an experiment in which i am trying to get an energy saving protocol in 802.11 MAC layer

i am using orinocco cards in ad-hoc mode and 2 computers with ubuntu 8.10
i am planning to switch over to bt4 as i need to dump the packets and then analyse them for throughput etc..

i am using tcpdump/wireshark for this

next stage i am going to fix the power of both the cards and vary the distances and analyse the loss in packets..

can someone recommend me utilities specifically in bt4

lastly i am planning to make one node as master and inject the protocol using some utility..please recommend me utilities to achieve my experiment..

thanx in advance
