摘要
详细介绍了无线传感网络中的RPL(IPv6 Routing Protocol for Low-Power and Lossy Networks)路由协议,从仿真环境、参数设定、仿真场景设计等方面对RPL路由协议的仿真进行了分析。利用cooja模拟器对RPL路由协议进行了仿真,并针对分组递交率和平均功耗两个性能指标对RPL路由协议进行性能评估。仿真结果表明,RPL路由协议在分组递交率方面适用于各个场景,并能很好地适应网络的动态变化;在功耗方面不适用于树型空间位置的场景,并且对于动态变化的网络会大大增加平均功耗。
RPL（ IPv6 Routing Protocol for Low-Power and Lossy Networks） routing protocol in WSN （Wireless Sensor Networks） is presented in detail. The simulation of RPL routing protocol is analysed in aspects of simulation environment, parameters setting and simulation scenarios de- sign. RPL routing protocol is simulated by using cooja simulator, performance of RPL routing protocol is evaluated according to the two per- formance indexes of the packet delivery ratio and the average power consumption. The simulation result indicates that in packet dilivery ratio, RPL routing protocol adapts to diffent scenarios and dynamic changes of the network well, in average power consumption, RPL routing protocol is not suitable for the scenario of tree type space position, and will increase the average power consumption greatly for dynamic changes of the network.
