single hop acks are already implemented in TinyOS. They are also active by default, except for broadcasts. You can go through the commands in interface PacketAcknowledgements provided by ActiveMessageC. Also if you want to enable retries by using these acks you will need to use the PacketLink interface provided by PacketLinkC
