Energy-efficient resource allocation method for use in heterogeneous wireless network

Abstract

The invention provides an energy-efficient resource allocation method for use in a heterogeneous wireless network. The method comprises the following steps: initializing power allocation of mobile terminals; determining the energy-efficient bandwidth resource allocation of a radio access technology; determining energy-efficient power resource allocation of each mobile terminal; adjusting the transmitting power of the mobile terminals, and calculating an energy efficiency sum; and repeating the steps above till the value of the energy efficiency sum of the heterogeneous wireless network is maximum. According to the energy-efficient resource allocation method, the energy-efficient bandwidth resource allocation is calculated firstly, and the energy-efficient power resource allocation is determined according to the bandwidth resource allocation, so that the value of the energy efficiency sum of the heterogeneous wireless network is increased after each resource allocation. Then, the steps above are repeated till the value of the energy efficiency sum is converged, and energy-efficient co-allocation of bandwidth resources and power resources is achieved, so that the uplink energy efficiency of the whole heterogeneous wireless network is increased.

Description

technical field [0001] The present invention relates to a method in the technical field of resource management in a heterogeneous wireless network, in particular to an energy efficient resource allocation method in a heterogeneous wireless network. Background technique [0002] With the development of wireless communication technology, green communication is becoming more and more important in heterogeneous wireless networks. The functions of mobile terminals are becoming more and more powerful, and the requirements for data transmission rate are higher, and at the same time, the problem of energy consumption of mobile terminals is more serious. Since the development of mobile terminal battery technology has not kept up with the development of wireless communication services, the problem of terminal energy consumption has seriously affected the quality of service for users. Moreover, as the usage time of the mobile terminal increases, the energy consumption of the mobile te...
