Based on such hierarchical structure, it is important to be aware of some parameters when a network is going to be configured. First, the maximum number of direct children is the limit of direct children that any node including coordinator is allowed to have. Likewise, the maximum network depth is the limit of parent-child relations from any tree leaf to the root node. Each node that joins ZigBee network receives temporary 16-bit long network address. Communication on the network level is performed based on this address while direct transmission between two neighboring devices is done based on the MAC address.
