/** * \addtogroup rime * @{ */ /** * \defgroup rimeuc Single-hop unicast * @{ * * 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. * * \section channels Channels * * The unicast module uses 1 channel. * */ /* * Copyright (c) 2006, Swedish Institute of Computer Science. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
