Embodiment Construction
[0021] Such as figure 1 Shown, in the asymmetric ZigBee network of the present invention, network node address distribution method comprises the steps:
[0022] Step 1, network pre-planning, divide the nodes in the network into root nodes, branch nodes and end nodes, and set the network address pool allocation ratio as P%;
[0023] Step 2, start the root node to establish a network, set the address pool range of the root node to the address range of the entire network, and assign addresses to the root node itself according to the principle of median address priority;
[0024] Step 3, the branch node is connected to the network, and the branch node applies for the branch node address pool from the parent node according to its own network branch expansion needs. The applied branch node address pool accounts for P% of the parent node address pool. The parent node receives the address pool After the pool application, judge whether there is a free unallocated address pool. If ther...

The invention provides a network node address assignment method in an asymmetric ZigBee network. The steps comprise: pre-planning a network, starting root nodes to build the network, accessing to the network by branch nodes and accessing to the network by terminal nodes. According to the address assignment method, the branch nodes apply to a father node for a branch node address pool according to respective network branch expanding demands; the assignment method of assigning addresses to the branch nodes by the father node according to a preset formula is abandoned; therefore the asymmetric ZigBee network is processed more flexibly; the problems of exhausting the addresses and low utilization rate are effectively solved; meanwhile, a mid-value address priority principle is convenient for executing an address pool dynamic adjusting method when the addresses are exhausted; and the problem of exhausting the addresses is effectively avoided.
Description
technical field [0001] The invention relates to an address allocation method, in particular to an address allocation method for network nodes. Background technique [0002] With the development of the Internet of Things, Zigbee wireless network has been widely used as an important wireless communication network. In traditional Zigbee, the network address allocation adopts the distributed address allocation mechanism (DAAM). DAAM is a method of symmetric network address allocation. This mechanism stipulates the maximum depth of the network, the maximum number of child nodes of the parent node, and the maximum number of child node routes before the network is constructed. The maximum depth of the Zigbee network using this method is 16 levels, and the maximum number of sub-node routes is 1 at this time, that is, there is no branch network. Moreover, it is very easy for some nodes in the network to run out of network addresses, while other nodes' network addresses are free. T...
