Patent Images
1. A method comprising:
- multicasting, by a wireless network device in a wireless network, a first message originated by the wireless network device and requesting reachability to an identified destination device via an identified target device class;
generating, by the wireless network device, plural paths for reaching the identified destination device based on receiving destination advertisement messages having been originated by respective target devices belonging to the target device class; and
pluricasting copies of a data packet to the identified destination device via the plural paths.
