Message caching for a node in a wireless mesh network

A method of wireless communication of a first node in a wireless mesh network, the method comprising:

• receiving a smart friend request message from a second node in the wireless mesh network,
• the first node being associated with a friend feature that includes one or more element messages intended for the second node when the second node is in a low power state,
• each of the element messages intended for the second node including an element address corresponding to one of a plurality of elements at the second node, and
• the smart friend request message indicating at least in part a hierarchy of element addresses such that the first node maintains the one or more elements messages for the second node based at least in part on the hierarchy of element addresses;
• and
• maintaining the one or more element messages for the second node based at least in part on the hierarchy of element addresses.

An apparatus for wireless communication of a first node in a wireless mesh network, the first node including a plurality of elements, each of the plurality of elements being associated with a different element address, the apparatus comprising:

• means for transmitting a smart friend request message to a set of nodes in the wireless mesh network,
• the set of nodes being associated with a friend feature that includes maintaining one or more element messages intended for the first node when the first node is in a low power state,
• each of the one or more element messages intended for the first node including an element address corresponding to one of the plurality of elements at the first node, and
• the smart friend request message indicating at least in part a hierarchy of element addresses such that a second node maintains the one or more elements messages for the first node based at least in part on the hierarchy of element addresses;
• and
• means for operating in the low power state during which the second node maintains the one or more element messages for the first node based at least in part on the hierarchy of element addresses.
