Implementation method of energy consumption error balance in indoor positioning system based on heterogeneous network

Abstract

The invention provides an energy consumption and error equalization realization method for an indoor positioning system based on a heterogeneous network. Clustering is performed mainly based on intelligent equipment in the indoor positioning system in the heterogeneous network with integration of a WLAN and a WPAN, and then a mechanism of dynamically selecting multiple cluster heads for each cluster is performed. Clustering of the intelligent equipment in the indoor positioning system is completed, the incentive value of each intelligent equipment acting as the cluster head is determined, and multiple cluster heads are selected according to the deployment relationship of the intelligent equipment so that dynamic switching of multiple cluster heads of each cluster is completed. According to the method, positioning accuracy can be greatly guaranteed by the mechanism of dynamic selection of multiple cluster heads of the intelligent equipment in the indoor positioning system based on the heterogeneous network, and energy consumption of the intelligent equipment can also be reduced so that equalization between energy consumption and error of the indoor positioning system can be realized.

Description

technical field [0001] The invention relates to the field of error energy consumption balance of indoor positioning systems, in particular to a method for realizing error energy consumption balance of indoor positioning systems based on heterogeneous networks. Background technique [0002] With the rapid development of mobile Internet technology, the concept of smart city has been proposed and rapidly popularized, location-based services (Location Based Service, LBS) have received more and more attention. The area of ​​life shows great vitality. Using smart terminals as a platform, WLAN-based indoor positioning has become a research hotspot in the fields of ubiquitous computing and location awareness in recent years because of its characteristics of pure software implementation and low cost of positioning systems. The high coverage rate of WLAN hotspot service makes it possible to ensure the realization of precise indoor and outdoor seamless positioning technology, which ju...
