Power Allocation Method Based on Coalition Game in Network Positioning

Abstract

The invention discloses a power distribution method based on alliance game in network positioning. The power allocation method mainly includes the following processes: using the geometric precision factor as the performance index of the positioning accuracy, and on the premise that the node power allocation satisfies a certain fairness principle, a consortium-based wireless sensor network positioning power consumption optimization model is constructed, and given The specific expression of the geometric precision factor is presented. Aiming at the complex calculation of the geometric precision factor value, an improved model of the optimization model is proposed by designing the formation algorithm of the alliance game and solving the utility function of the optimization model. On the premise of ensuring the positioning accuracy, based on the double-sided bilateral ranging agreement, a distributed measurement method for solving the alliance and power allocation is proposed. The method of the invention can be applied to the power distribution optimization problem in the wireless sensor network positioning stage.

Description

technical field [0001] The invention relates to a power distribution method based on alliance game in network positioning. Background technique [0002] The Internet of Things is a new type of network that extends and expands to information interaction and communication between "things and things" on the basis of the Internet. Since the information perception and collection, tracking, manipulation, and information interaction of "things" in the Internet of Things are closely related to the geographical location information of nodes, positioning technology to achieve accurate location information acquisition has become a very important research topic. , is an important technical foundation of the Internet of Things. In addition, many other technologies often need to use positioning technology to obtain the real-time location information of objects, thus deriving a series of IoT applications based on location information. For example, in the fields of transportation and logi...
