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

Embodiment Construction

[0027] As used herein, the Internet of Things (IoT) refers to the Internet Protocol (IP)-based infrastructure that interconnects IoT nodes or things to the Internet. As used herein, the term IoT may refer to any network where devices can communicate with each other, and thus IoT may also be referred to as an IoT system or a Machine-to-Machine (M2M) communication system. An IoT system can be composed of IoT items, IoT entities, IoT services, IoT applications, etc. Although devices, applications, services, etc. are often referred to herein as "IoT" devices, applications, services, etc., it will be understood that the "IoT" qualifier is presented by way of example, and not limitation. For example, an IoT item or node refers to a uniquely identifiable physical or virtual item accessible via connectivity. Thus, an IoT node may be a host, router, or any other device that communicates via what may be referred to as an IoT network. As used herein, an IoT host may refer to an IoT nod...

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...
