Intelligent access method for comprehensive benefit maximization in heterogeneous wireless network

Abstract

The invention requests to protect an intelligent access method for comprehensive benefit maximization in a heterogeneous wireless network, and provides an intelligent access algorithm for comprehensive benefit maximization in order to solve the problems of frequent access and lack of access strategy adjustment according to the moving speed of a user in a current access algorithm in the heterogeneous wireless network. The method comprises: firstly, calculating the maximum transmission rate of a user according to the received signal strength and the available bandwidth of the user and using themaximum transmission rate as the current benefit; secondly, obtaining the transmission rates of the user at the next several moments through a prediction method, and taking the transmission rates as long-term benefits in combination with a weight decreasing method; and finally, combining the current benefit with the long-term benefit according to the moving speed of the user. Experimental resultsshow that the access frequency can be effectively reduced, the system throughput is improved, and the method is suitable for user access at different moving speeds.
