微移动切换算法

On Mic-Mobility Handoff Algorithm

在混合移动网络中,频繁的切换是不可避免的.切换引起的重新建立数据连接将导致时延和占用大量的网络带宽.微移动切换算法提出了一个交叉路由的切换方案,该方案可以减少延迟服务中断期间所发生的切换过程.微移动切换算法的实现是移动节点在向前推进的过程中,预先为下一个节点发送资源请求以保留该移动节点切换发生,确定交叉位置的路由器以减少带宽的浪费.该算法在网络模拟器版本2平台上进行模拟,结果表明,该切换方案减少了移动节点发送数据的时延,降低了数据丢包率以及增大了网络吞吐量.

Handoff is a processing to establish data connection. A failed data connection should produce useless message and loss rations, which have to send to source node for new connection. In mix-network, handoff must happen, and re-establish new connection, which gives delay and utilizes sources. This paper deals not only with mic-mobility handoff algorithm, but also with establishment of a crossing path in order to reduce delay. Mic-mobility handoff algorithm is keeping nodes which used for handoff and identity the handoff router. The work will be simulated in NS2 platform and the results show that it gets higher effi- ciently about the handoff.
