【摘要】 针对低功耗有损网络(low power and lossy network,LLN)中负载不均衡以及高控制开销的问题,提出一种基于流量自适应分配的多汇聚节点LLN路由协议(traffic adaptive assignment based multi-sink routing protocol for LLN,TAAM-RPL)。介于多个汇聚节点之间的节点可同时加入到多个RPL实例中;在不增加额外控制开销的前提下,多重身份节点便可获知其到达各个汇聚节点整条路径的负载状态;多重身份节点可根据其到达各个汇聚节点整条路径的负载状态进行数据流量自适应分配。仿真结果表明,该协议可行有效,能够提升网络各方面性能。更多还原

【Abstract】 Due to the load cannot balancing and high-overhead in low power and lossy networks(LLN),a traffic adaptive assignment based multi-sink node routing protocol for LLN(TAAM-RPL)was proposed.The nodes between the multiple sink nodes could join multiple RPL instances simultaneously.The multiple identify nodes could get the load status of all the paths to the sink node without adding additional control overhead.The multiple identify nodes could adaptively allocate traffic according to the load status of all the paths to the sink node.The simulation results show that the proposed protocol is effective and feasible,and it can effectively improve the performances of all aspects of the network.更多还原
