中文摘要:
      本文提出了一中基于多基站的无线传感器网络Anycast路由算法,可以解决多基站无线传感器网络中基站的路由选择。算法为网络中每个基站都建立一颗自己的Anycast树,网络中所有节点选择路径开销最小的邻居节点加入到对应基站的Anycast树中。本文提出的Anycast多基站路由算法可以根据不同的网络时延需求设置不同的权重参数来选择最优的路径,以达到实现不同时延要求无线传感器网络的应用。所有源节点采集的数据根据其加入的Anycast树的树状结构进行数据传输并送达基站。本文提出的Anycast路由算法在多基站的无线传感器网络中可以有效降低网络能耗和明显延长网络生命周期,可以很好的解决多基站的无线传感器网络架构通信模式。
英文摘要:
      For resolving the sinks selection and routing protocol design in the process of data transmission of wireless sensor networks with multiple sinks, a communication based on Anycast communication techniques is provided in the article. For each sink, establishes an Anycast tree, where sink is the root and all nodes choose to join in an Anycast tree according to the path cost model. In the process of route establishment, according to the communication quality requirements, a sensor will select an appropriate node as its parent node, and forms an optimal route ultimately. The data generated by sources will be transferred to the nearest sink node along the Anycast tree. Anycast scheme can resolve the sink selection and data transmission for wireless sensor network with multiple sinks effectively. Simulation results show that Anycast routing model proposed can reduce the energy consumption and prolong the network life effectively.
