异构无线网络中的共享载波垂直网络转换算法
Shared carrier vertical network transformation algorithm in heterogeneous wireless networks
摘要
Abstract
In order to enhance the spectrum efficiency in heterogeneous wireless networks, the idea of dynamic spectrum allocation (DSA) used in cognitive radio was introduced into the heterogeneous wireless networks, the idea of vertical handoff for multi-mode mobile users was introduced into the base station side, thereafter, the shared carrier vertical network transformation (SCVNT) algorithm in heterogeneous wireless networks was proposed. The theoretical analysis and simulation results show that SCVNT algorithm can effectively enhance the total channel efficiency in heterogeneous wireless networks, improve fairness in resource allocation, and will be able to achieve smooth upgrade, which is of a relatively high application value.关键词
