摘要:

无线网络虚拟化技术是5G研究的热点,其中虚拟网络映射问题是关键技术之一。对无线网络虚拟化映射问题进行介绍,针对现有映射算法不能完全适应网络动态变化的不足,以最小化映射成本为目标,提出一种新的网络中带宽和功率资源的联合映射算法(WVNEA-JBP,wireless virtual network embedding algorithm based on joint bandwidth and power),同时考虑无线链路之间的干扰对映射性能的影响和路径分离。实验结果表明,该算法在实现资源高效利用的同时,提高了无线虚拟网络映射成功的概率。

Abstract:

Wireless network virtualization has become one of the promising techniques in fifth generation mobile networks (5G),and the virtual network embedding plays a very important role.A model was formulated to describe the problem and a wireless virtual network embedding algorithm based on joint bandwidth and power allocation (WVNEA-JBP) was put forward,which selected the suitable node and path to serve the data transmission from virtual networks.In order to minimize the overhead while satisfy the higher capacity request,this algorithm considered the impact of interference of wireless links and supports path splitting.A case study was introduced to show how WVNEA-JBP to work.Furthermore,simulation results show that WVNEA-JBP is able to accomplish the efficient utilization of network resources and improve the accept rate of virtual network requests.

Key words: wireless network virtualization, embedding algorithm, load balancing, separate paths
