| 摘要: |
| 提出了一种中继蜂窝网络的基于负载均衡的中继节点选择策略(Load Balancing Rela
y Selection，LB-RS)。根据每个用户的具体信道状况以及中继节点服务的用户数目，LB-RS
以分布式的方式为每个用户选择最优的中继节点。仿真结果表明，与基于单一物理层参数的
中继节点选择算法相比，所提出的中继选择算法综合考虑了物理层的信道状况以及MAC层
的资源与用户状况，有效地利用中继节点选择来实现小区内的负载均衡，获得了吞吐量性能
与用户公平性之间的折衷。 |

| Abstract: |
| A load balancing relay selection algorithm(LB-RS) is presented for rel
ay based cellular networks. According to current user channel conditions as well
as the user numbers that relay serves, LB-RS chooses the optimal relay node for
each user in a distributed way. Simulation results demonstrate that compared wi
th other relay selection schemes only based on physical parameters,LB-RS
achieves load balancing through effective relay selection method. This is
realized by jointly considering physical layer conditions as well as MAC layer
con
ditions, so as to efficiently obtain a tradeoff between the system throughput an
d the user equity. |
