基于稳定闭域的异构无线网络混合路由策略

Stable enclosure based hybrid routing schema in heterogeneous wireless networks

分析了异构的网络模型,并提出了一种基于MANET稳定闭域的混合路由策略,使得基于该路由策略设计的路由协议能够实时地根据本地拓扑状态进行转换,在稳定闭域内使用AODV提高路由转发的效率。当数据分组转发到闭域边界后,将转换为改进的Prophet路由继续在非连通区域内寻路,以充分利用MANET与DTN路由的优势。仿真实验证明了该路由策略的可行性,通过比较多种路由算法验证了在特定的异构网络环境下该路由策略的高效性。

The model of heterogeneous wireless networks was analyzed and a hybrid routing schema based on MANET stable enclosure was proposed.This schema could transform the routing protocol between MANET and DTN based on the local topology in real time.In the stable enclosure,AODV was used to improve packet relaying efficiency.When packet relayed to the disconnected area,the routing protocol transcended to Prophet to avoid routing failed.It fully used the advantage of MANET and DTN routing protocol.The feasibility of the proposed algorithm is demonstrated,and it is more efficient than the other DTN routing protocols used in the heterogeneous wireless networks.
