Embodiment

[0031] Embodiment: In this hierarchical network, the network is divided into 4 levels, starting from the bottom layer network, which are respectively level 3, level 2, level 1 and level 0 networks. The network nodes on each level of network can self-organize the network to form an self-organizing Mesh network, and the maximum number of nodes in each network will reach 255. The nodes of the upper-level network will serve as the routing nodes of the lower-level network, and one upper-level node is responsible for a lower-level network, providing cross-level or cross-network communication services for the lower-level network. When a node in a certain network wants to send data to a node in another network, the node will send the data to the superior node in charge of the network, and then the node does not need to care about the subsequent data sending process, the superior node will The data is sent to the routing node of the network where the destination node is located, and th...

Abstract

The invention discloses a grading type wireless sensor networking method and aims to provide a grading type wireless sensor networking method which has strong convergence and can be freely combined. In the method, a plurality of nodes and a server are provided. The whole network is classified into four grades, and after entering the network, each node is combined with the original network to forma Mesh network and requests to distribute an IP address. In communication, if the target node adopts an ID address in the same network, the IP address is adopted in different networks, the quick convergence property of a route can be greatly enhanced, and the network can be formed by free combination. The invention is suitable for various wireless sensor networks.

Description

technical field [0001] The invention relates to a networking method of a wireless sensor network, in particular to a hierarchical wireless sensor network networking method using two sets of addresses. Background technique [0002] With the rapid development of micro-electromechanical systems, low-power and highly integrated electronic devices and wireless communication technology, the wireless sensor network is formed by the emergence of low-cost, low-power, micro-volume, multi-functional wireless sensor node devices that are different from A new type of network in the traditional sense of the network. It integrates sensor technology, embedded computing technology, modern network and wireless communication technology, distributed information processing technology, etc., and can monitor, perceive and collect information of various environments or monitoring objects collaboratively in real time through various integrated micro-sensors , process the information through an embe...
