Research on Power Wireless Network Quality Evaluation Method Based on Multi-dimensional Index

摘要

The comprehensive evaluation of power wireless network quality is an important means to find out the short board of wireless network service, optimize the service ability of wireless network and improve the service level of power service. In this paper, from the point of view of security, accessibility and reliability of power wireless network, a comprehensive evaluation scheme is established in order to reflect the service quality of power grid reasonably and accurately. The density-based fuzzy clustering method is proposed to obtain the central index, and the grey relational analysis method based on entropy weight is used to remove the redundant non-central index in the evaluation scheme to overcome the lack of expert experience and ensure the accuracy of the index. Afterwards, the evaluation indicators are calculated through a combination of subjective and objective mixed weight to achieve a comprehensive assessment of wireless network bearing quality. The result of case study shows that the comprehensive evaluation scheme proposed in this paper can effectively and accurately reflect the quality of service of power wireless network.
