1. A method, comprising:
- selecting, by a particular node in a shared-media communication network, a primary node in the shared-media communication network toward a destination;
determining a frequency-hopping schedule of the primary node; and
determining one or more backup nodes for the primary node, based on a frequency-hopping schedule diversity between the primary node and the one or more backup nodes.

Abstract
In one embodiment, a primary node in a shared-media communication network is selected by a node toward a destination. In response to determining the primary node, the node determines a frequency-hopping schedule of the primary node. One or more backup nodes for the primary nodes are then determined based on a frequency-hopping schedule diversity between the primary node and the one or more backup nodes.

13. A method, comprising:
-
selecting, by a particular node in a shared-media communication network, a primary node in the shared-media communication network toward a destination; determining one or more backup nodes for the primary node; and in response to determining the one or more backup nodes, determining a frequency-hopping schedule of each backup node, wherein each frequency-hopping schedule has a least degree of overlap with a frequency-hopping schedule of the primary node. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus, comprising:
-
one or more network interfaces to communication with a shared-media communication network; a processor coupled to the network interfaces and adapted to execute one or more processes; and a memory configured to store a process executable by the processor, the process when executed operable to; select a primary node in a shared-media communication network toward a destination; determine a frequency-hopping schedule of the primary node; and determine one or more backup nodes for the primary node, based on a frequency-hopping schedule diversity between the primary node and the one or more backup nodes. - View Dependent Claims (19, 20, 21)

24. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that select a primary node in a shared-media communication network toward a destination; program instructions that determine a frequency-hopping schedule of the primary node; and program instructions that determine one or more backup nodes for the primary node, based on a frequency-hopping schedule diversity between the primary node and the one or more backup nodes.
