基于改进牛顿法的异构无线网络性能改进

Performance Improvement of Heterogeneous Wireless Networks using Modified Newton Method

R. Shyam Sundar, S. Nanda Kumar

摘要:

其中不同无线电接入技术(RAT)共存的异构无线网络被广泛部署用于各种服务并且支持各种业务需求、信道分配。在异构无线网络下,用户可以通过单个或多个RAT同时发送数据。本文的目标是选择最佳的服务和功率分配的带宽。采用改进牛顿法的分布式联合分配算法最大化系统总容量。我们通过数值结果验证了所提出的算法的性能。

英文摘要:

The heterogeneous wireless networks where coexistence of different Radio access technology (RAT) are widely deployed for various services and support various traffic demand, channel allocation. Under heterogeneous wireless networks, a user can send data through a single or multi RATs simultaneous. The objective of this paper is to choose the optimal bandwidth for the services and power allocation to that bandwidth. The proposed distributed joint allocation algorithm using modified Newton method is adopted to maximize the total system capacity. We validate the performance of the proposed algorithm through numerical results.
