中文摘要:

      在RPL(routing protocol for LLN)协议应用于农田墒情监测传感网络的过程中，保证网络中的节点能够长期有效工作成为关键问题。为此，设计了一种基于间隔更新思想的控制算法IUTA，对在一致性和不一致性事件发生时的处理机制进行了改进。在网络中节点复杂度变化的情况下，通过Cooja实验仿真模拟了网络中节点传递数据节省的功耗以及成功率两者动态变化的过程。结果表明，IUTA有效降低网络中节点传输功耗，同时对数据传输成功率影响甚微。

英文摘要:

      In the RPL(routing protocol for LLN) used in the process of agricultural soil moisture monitoring sensor network,to ensure that the nodes in the network can work effectively for a long time becomes a key problem.Therefore a control protocol IUTA based on the idea of intermittent update is designed and the treatment mechanisms of consistency and inconsistency events are improved.In the case of node complexity in the network,dynamic changes between saving power and success rate during transferring data are simulated by Cooja experiment simulation.The results demonstrate that IUTA can effectively reduce power,and has little influence on the success rate during the node transmission in the network.
