NEIGHBOR DISCOVERY TO SUPPORT SLEEPY NODES

摘要

Many internet of things (IoT) are “sleepy” and thus occasionally go into a sleep mode. As described herein, nodes in a connected network of nodes may determine that other nodes in the network are sleepy. Further, nodes, such as endpoint devices and routers for example, may process packets in the network based on a reachability state of their neighboring nodes.

1. In a system comprising a plurality of nodes that communicate with each other via a network, a method comprising, at a first node of the plurality of nodes:
receiving a packet that is targeted for a second node of the plurality of nodes; determining that the second node is a sleepy node configured to enter a low power state and suspend communications with the first node; determining a reachability state of the second node; and processing the packet based on the determined reachability state.
