光纤无线宽带混合接入网(WOBAN)是一种新型的具有前景的混合接入网,通过改进其无线端网络的路由算法能够有效克服WOBAN的瓶颈限制。最小跳路由算法(MHRA)和最小时延路由算法(MDRA)是将Dijkstra算法应用在WOBAN前端无线Mesh网(WMN)中的新型路由算法,低负载情况下两算法性能相近,高负载情况下MDRA具有更好的网络性能。通过仿真比较,高负载情况下MDRA的时延和TDR性能明显优于MHRA。
Optical fiber wireless broadband hybrid access network (WOBAN) is a new and promising hybrid access network, which can effectively overcome the bottleneck of WOBAN by improving the routing algorithm of its wireless network. The minimum hop routing algorithm (MHRA) and minimum delay routing algorithm (MDRA) are new routing algorithms that apply Dijkstra algorithm to the WMN of the front end of WOBAN. The performance of the two algorithms is similar under low load conditions. The MDRA Have better network performance. Through simulation comparison, the MDRA’s delay and TDR performance is obviously superior to MHRA under high load.
