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.
Aiming at the unidirectional link which is ubiquitous in Ad hoc networks, a unidirectional link advertisement strategy based on power adjustment is proposed, which can inform unidirectional link status information to the upstream nodes of the link in order to improve network connectivity , And improve the success rate of route establishment.On the basis of this strategy, a method of establishing route by using one-way link is given.The simulation results show that the link state advertisement strategy and route establishment mechanism are different in end-to-end delay, routing path Length and other aspects of the research purposes.
