Intelligent Access Method for Maximizing Comprehensive Benefits in Heterogeneous Wireless Networks

Abstract

The present invention claims to protect an intelligent access method for maximizing comprehensive benefits in a heterogeneous wireless network. In a heterogeneous wireless network, the current access algorithm has frequent access and lacks the problem of adjusting the access strategy according to the user's moving speed , propose an intelligent access algorithm for maximizing comprehensive benefits. First, calculate the user's maximum transmission rate according to the user's received signal strength and available bandwidth, and use it as the current benefit; secondly, use the prediction method to obtain the user's transmission rate at the next few moments, and combine it with a weight-decreasing method to use it as a long-term benefit. Benefits; finally, combine current and long-term benefits based on user movement speed. Experimental results show that the present invention can effectively reduce access times, improve system throughput, and adapt to user access with different moving speeds.

Description

technical field [0001] The invention belongs to an access method in a heterogeneous wireless network and belongs to the field of mobile communication.
