Embodiment 1

[0077] A method for distributed resource allocation based on cooperation in a heterogeneous wireless network, comprising the following steps:

[0078] In step 1, the intelligent centralized controller collects basic parameters of the heterogeneous wireless network and available bandwidth resources therein. The series of heterogeneous network base stations are located in the community. There are 3 heterogeneous wireless networks in the community. There is only 1 base station in each network. The 3 base stations are all located in the center of the community. The service radius of each base station is 500m, 26 Each mobile terminal is set at a distance of 300m from the center of the cell, and all receive bandwidth resources from each base station. The three heterogeneous wireless networks are respectively marked as 1, 2, and 3, and the internal base stations of each network are marked as 1. Therefore, the wireless network set N and the number of heterogeneous networks in the set...

Abstract

The invention discloses a method for allocating distributed resources of a heterogeneous wireless network based on cooperation, which includes the following steps: Step 1, collecting the basic parameters of the heterogeneous network and the available bandwidth resources in the heterogeneous network, the bandwidth resources are internal of each network of the heterogeneous network The bandwidth resources of each base station or access point; step 2, collecting resource usage requests of user terminals; step 3, using the particle swarm optimization algorithm to allocate bandwidth resources in the heterogeneous network. The heterogeneous wireless network distributed resource allocation method provided by the invention ensures that the heterogeneous network bandwidth resources are optimally utilized.

Description

technical field [0001] The invention belongs to the technical field of computer networks, in particular to a method for allocating distributed resources in heterogeneous wireless networks based on cooperation. Background technique [0002] In the past ten years, various wireless access technologies have emerged and been widely developed. The goal of the current wireless communication system is to use different access technologies to provide users with universal access multimedia services. This enables mobile users to use multi-mode mobile devices to access heterogeneous wireless networks, including Wireless Local Area Network (WLAN for short), Universal Mobile Telecommunications System (UMTS for short), Wireless Metropolitan Area Network (WiMax for short), and various 3G, 4G access technology to obtain rich application services. In a heterogeneous wireless network, a resource management mechanism (RRM for short) should be designed to meet the needs of both users and operat...
