在无线传感器网络中,路由协议不仅关系单个节点的能量消耗,更关系整个网络的能量的均衡消耗,降低消耗才能延长整个网络的生存期。因此,在无线传感器网络体系结构中,网络层的路由技术对无线传感器网络的生命周期至关重要。同时,无线传感器网络的特点是以数据为中心,这在路由协议中的表现最为突出。选择路径可以不用根据节点的编址,更多的是根据感兴趣的数据建立数据源到汇聚节点之间的转发路径。 In wireless sensor networks, routing protocols not only relate to the energy consumption of a single node, but also to the balanced consumption of energy of the entire network, and reduce the consumption to prolong the lifetime of the entire network. Therefore, in the wireless sensor network architecture, the routing technology at the network layer is crucial to the life cycle of wireless sensor networks. At the same time, wireless sensor networks are characterized by data as the center, which is most prominent in routing protocols. The selection path may not be based on the addressing of the node, and more on the basis of the data of interest to establish the forwarding path between the data source and the sink node.
