摘　　要：机会路由采用路由推迟策略,该推迟的路由抉择是对传统路由方式的颠覆。基于此,提出一种适应无线信道不稳定性的机会路由机制,并在Linux操作系统上以内核加载的方式实现该机制。仿真结果表明,该机制能提高数据包的投递率,降低端到端时延,且其性能稳定,几乎不受无线信道变化的影响,更能够适应无线链路的不稳定性和不可预测性。Opportunistic routing protocol adopts routing-delayed mechanism.The mechanism is a subversion of the traditional routing.This paper designs an opportunistic routing protocol that can adapt to volatility of wireless channel and realizes the protocol on Linux platform as a kernel loadable module.The preliminary results show that opportunistic routing protocol can improve packet delivery and decrease time delay greatly.Most importantly,the mechanism is almost unaffected by the changing wireless channel and can adapt to its instability and unpredictability better.
