* The unicast module sends a packet to an identified single-hop
|
|
* neighbor. The unicast primitive uses the broadcast primitive and
|
|
* adds the single-hop receiver address attribute to the outgoing
|
|
* packets. For incoming packets, the unicast module inspects the
|
|
* single-hop receiver address attribute and discards the packet if
|
|
* the address does not match the address of the node.
