Neighbor discovery to support sleepy nodes

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 845,635, filed July 12, 2013, the disclosure of which is hereby incorporated by reference as if set forth in its entirety herein. Background technique [0003] The Internet of Things (IoT) generally refers to the global infrastructure of interconnecting things to the Internet. An item in IoT may refer to a uniquely identifiable physical or virtual item accessible via network connectivity. Such items can be integrated into information networks through intelligent interfaces. An IoT system can refer to any system within the Internet of Things. An IoT system may include one or more end devices, such as, for example, sensors, which may be referred to as front ends. An IoT system may include gateways to other networks, which may be referred to as backends. Many IoT devices have at least some combination of limited battery pack power, sm...

Problems solved by technology

Existing approaches for supporting IoT sleepy nodes have several disadvantages

For example, nodes often do not know whether other nodes in the network are dormant, and therefore do not communicate efficiently and effectively with dormant nodes in the network
