| 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. |
