Embodiment Construction

[0019] The energy consumption of transmitting data in wireless communication is related to the 2 to 4th power of the effective transmission radius. To reduce the energy consumption of nodes, the effective transmission radius of nodes must be reduced. The reduction of the effective transmission radius reduces the coverage area of ​​a single node. In order to achieve a wide coverage of the wireless sensor network, a multi-hop relay method must be used to transmit data. At the same time, Zigbee’s routing algorithm allows developers to , balancing unit cost, energy consumption, and complexity to achieve maximum efficiency.

[0020] In order to adjust the hierarchical structure, the ZigBee 2006 standard distributed address allocation algorithm is adopted. Different from the standard ZigBee networking process, here a layer attribute is added to each routing device 2 as the attribute Depth to identify the layer in the network where the device is located. The default value is 0xff. Th...

Abstract

The invention discloses a statistical-optimization-based ZigBee hierarchical routing networking method. A network comprises a coordinator and node routers. The method comprises the following steps that a level attribute is added to each piece of equipment as an attribute Depth for identifying the level of the equipment in the network; and after all the equipment is successfully networked, each piece of equipment maintains a forwarding count parameter Count, and a superior node regulates the level of the node according to a count value of a subordinate node. According to the method, statistics on data loads of the routers can be made in real time, the routers can be allocated and scheduled according to service needs, the communication quality of the network is ensured in an indoor positioning system, and the routers can be deployed in a large scale. The method aims to change a networking mode and a routing mode for a sensor network to optimize the networking method without changing network hardware composition. The method is convenient to use, high in accuracy and practicability and widely applicable to various indoor positioning systems.

Description

technical field [0001] The invention relates to a ZigBee hierarchical routing networking method based on statistical optimization. Background technique [0002] ZigBee technology is a short-distance, low-complexity, low-power, low-data-rate, low-cost two-way wireless communication technology or wireless network technology. and wireless communication technology in terms of application software. In actual application, ZigBee technology also has the disadvantages of conventional wireless communication, such as large energy consumption of transmitted data, uneven signal and limited large-scale coverage area. The choice of routing algorithm is fundamental to solve the above problems, and plays a vital role in its optimal path selection. [0003] The routing algorithms of traditional wireless sensor networks can be divided into flat routing protocols, network layered routing protocols, and geographic location information routing protocols. The bottom layer of the Zigbee protoco...
