具有定向天线的无线网状网络有望成为在农村地区提供无线宽带服务的一种新的有前途的技术和经济的方法。在这些网络中,多个非重叠信道的有效使用可以通过允许更多的并发传输来显著增强网络容量。然而,无线mesh网络的性能严重下降的干扰与重叠的信道在附近地区的链路之间。本文讨论了农村无线网状网络信道分配中的联合利用和平衡问题。我们设计了一个新的信道分配框架的目标是优化整个网络的信道资源利用率,同时考虑均衡分配。这种平衡的信道分配允许信道的成本有效的重用,而不会导致农村无线网状网络中的质量损失。我们还评估了一些笛卡尔积图,流行的互连网络拓扑结构的建议框架。该框架保证这些拓扑结构需要少量的通道进行平衡分配。
Wireless mesh networks with directional antennas are expected to be a new promising technology and an economic approach for providing wireless broadband services in rural areas. In these networks, the effective use of multiple non-overlapping channels can significantly enhance the network capacity by allowing more concurrent transmissions. However, the performances of wireless mesh networks are severely degraded by interference between links with overlapping channels in nearby areas. In this paper, we address the issue of joint utilization and balance in channel assignment for rural wireless mesh networks. We design a new channel assignment framework with the goal of optimizing the channel resource utilization across the entire network while taking balanced allocation into account. This balanced channel assignment allows for the cost-effective reuse of channels without a consequent loss of quality in the rural wireless mesh networks. We also evaluate the proposed framework on some Cartesian product graphs that are popular interconnection network topologies. The framework guarantees that these topologies require a small number of channels for balanced allocation.
