无线Mesh网络中的信道分配研究

Research on Channel Assignment in Wireless Mesh Networks

无线Mesh网络是广播网络的一种特殊方式,它结合了WLAN网络和ad hoc网络的优点,网络通过跳跃通信和相对降低基础设施在电线和硬件方面的成本来提供与因特网最后一英里的连接。信道分配方案是提高无线Mesh网络容量的主要途径。随着用户数量的增加,网状网络对信道资源的公平利用一直是一个挑战。合理利用多信道和节点的多接口,不仅增加了网络的总吞吐量和可扩展性,而且为信道分配方法带来了新的曙光。针对现有信道分配方案进行了详细讨论。

The wireless Mesh network is a special way of broadcasting networks that combines the advantages of WLAN networks and ad hoc networks that provide connectivity to the last mile of the Internet by jumping communications and relatively reducing the cost of infrastructure in terms of wire and hardware. Channel allocation scheme is the main way to improve the capacity of wireless Mesh network. With the increase in the number of users, the mesh network on the fair use of channel resources has been a challenge. Reasonable use of multi-channel and multi-interface nodes, not only increased the total network throughput and scalability, but also for the channel allocation method has brought a new shine. The existing channel allocation scheme is discussed in detail.
