摘要:

针对普遍存在于Ad hoc网络的单向链路问题,提出了基于功率调整的单向链路通告策略. 该策略可将单向链路状态信息通告到链路上游节点,以提高网络的连通能力,提升路由建立成功率. 在采用该策略的基础上,给出了利用单向链路建立路由的方法. 仿真结果表明,该链路状态通告策略和路由建立机制在端到端延迟、路由路径长度等方面达到了研究目的.

Abstract:

In Ad hoc networks, a wireless link may be unidirectional because of the difference of transmission range and transmission capability of each node, etc. The features of unidirectional links were studied in Ad hoc networks. A unidirectional link-state advertisement mechanism based on power adjustment (ULAPA) is designed. ULAPA can improve the network connectivity. According to ULAPA, a unidirectional link-state advertisement mechanism based on accurate power adjustment (ULAAPA) is proposed. ULAAPA can decrease energy consumption of nodes through accurate power adjustment. A routing method using unidirectional links is described for Ad hoc network. Results of simulation show some performances are better than those of traditional routing mechanisms.

Key words: Ad hoc network, unidirectional link, power adjustment, advertisement mechanism
