1. A device comprising:
a storage device;
a wireless transceiver to send and receive data; and
application layer logic and network layer logic coupled with the storage device and the wireless transceiver, to cooperate to coordinate formation of a network with one or more child nodes, wherein:
the application layer logic, in response to an association request received from a child node, to initiate a request to the network layer logic to perform an association procedure with the child node to establish a network connection, via the wireless transceiver, with the child node;
the network layer logic is to perform the association procedure with the child node to associate the child node with the device, including obtaining a media access control (MAC) address of the child node, from the child node, and allocate a logical address for the child node that uniquely identifies the child node in the network; and
the application layer logic is to store an identifier associated with the child node in the storage device, the identifier including the MAC address of the child node obtained by the network layer logic, and the logical address of the child node allocated by the network layer logic;
wherein to coordinate formation of the network further includes:
the application layer logic retrieving the identifier, and providing the MAC address of the child node to the network layer logic to initiate automatic re-establishment of the network connection, via the wireless transceiver, with the child node, without waiting for another association request from the child node, based on detection of losing the network connection with the child node; and
based on detection of losing the network connection with the child node, the network layer logic at the device performing a direct join procedure, as opposed to the association procedure, using a previous logical address of the child node or a newly allocated logical address to re-join the child node to the network.
