无线网状网域间无缝切换技术研究与设计

针对无线Mesh网络缺乏对域间移动切换支持的问题,提出了一种高效的无线Mesh网络域间无缝切换技术,降低切换时延,实现无线Mesh网络域间的无缝切换.通过对STA物理地址与IP地址的绑定,设计地址对应关系表和路由算法,并在源MAP与目标MAP建立缓存机制,保存切换过程中的通信数据包,实现在无线Mesh网络域间的有效切换.通过网络设备的缓存策略与新的算法寻址机制,减少STA在切换过程中的压力,有效降低了切换过程的丢包率,实现Mesh网络域间的无感知与快速切换.

Inter-Domain Seamless Handoff Scheme Research for Wireless Mesh Network

In order to support the inter-domain handoff for wireless Mesh Network, an efficient seamless inter-domain handoff for wireless Mesh Network is proposed. The technology uses seamless handoff to reduce the handoff time delay. By binding the IP address with the STA physical address, address mapping table and routing algorithm in STA are designed. In order to realize the effective inter-domain handoff in wireless Mesh Network, the buffering strategy is built between source MAP and target MAP and the communication data package is kept during the handoff process. By employing the buffering strategy of network devices and the new path searching algorithm, the pressure during switching for STA and the package lose rate is reduced, and the seamless and quick switching inter-domain handoff for wireless Mesh Network is realized.
