You can turn on a rudimentary ACK with MacControl.enableACK(),
but it is not very good on mica2s. Otherwise you need to build
your own protocol on top. Look back a couple days on the list,
I reposted pointers to my treatise on radio reliability which
has some detail and code on the ACK mechanism.

Hi
I am trying to set up a simple communication model between 2 nodes, one
as a base station and another as a sensor node. My concern is the
communication between the 2 nodes, i.e. sending and receiving of
packets. I have manage to sent messages using Generic Comm and for the
receiving part, i actually made used of TOSBase. I used Listen.Java to
monitor the packet data. I realise that Generic COmm doesn't offer any
kind of acknowledgment when a packet is received. The sender just keep
sending the packets to the base node. I need advice/suggestions on how
to implement acknowledgment before sending the next packet. Thanks
