摘要
传统的路由协议都是针对特定的有线或无线网络,仅仅考虑路由的建立过程、路由建立过程中的收敛速度、路由维护的网络开销及路由动态更新时环路的避免等性能。将其用于有线无线混合传输网络会导致较低系统性能。机会式路由选择算法综合分析了无线链路状态和网络时延的影响,得出了各路径优先级的计算表达式,在路由选择时根据各条路径的优先级来选择路由。仿真结果表明,与传统路由算法相比较,该算法能够提高系统吞吐量和减少系统传输时延。
The design of traditional routing algorithms is aimed to specific wireline network or wireless network.The focus is to meet the performance requirements of route establishment,convergence speed of route establishment,network expanse of route maintenance and loop avoidance of dynamic route updating.Opportunistic routing algorithm combines the influence of wireless link states and network delay,gets the mathematical expression of multiple transmission path priority and then decides the signal transmission route based on the priority.Simulation results show that it can enhance the system throughput and decrease the transmission delay comparing with traditional routing algorithm.
