摘要:: 小规模、分布集中的WSNs（Wireless Sensor Networks，无线传感器网络）适宜采用平面路由协议，但在平面路由协议中，传统的洪泛路由算法以广播的方式在整个网络中传输查询请求和查询结果数据帧，消耗了较多的传感器节点能量。导致节点过早失效。论文对传统的洪泛路由算法进行改进，提出并实现了一种节能路由算法BRE-Flooding（Based on the Remaining Energy Flooding，基于剩余能量的洪泛算法）。在算法中，节点依据剩余能量决定是否接收和转发数据帧；节点维护由剩余能量、距离网络中聚合节点（Aggregation Node）的跳数等信息组成的邻居路由信息表，并依据数据帧中表示该查询请求关键程度的属性，结合邻居路由信息表动态确定向哪几个（或全部）邻居节点转发数据帧。经实验仿真，表明所提算法在节省节点能量消耗及网络负载均衡方面具有较好的表现

Abstract:: Flat routing protocols are appropriate for small-scale and concentrated WSNs （Wireless Sensors Networks ）. However, since flooding routing algorithm transmits queries and query results packets across the network by means of broadcasting, sensor nodes energy is greatly consumed,eventually resulting in the premature failure of nodes. In order to improve the traditional flooding routing algorithms, propose and implement a new energy-efficient routing algorithm-BRE-Flooding （Based on the Remaining Energy Flooding ）. What is new in this new routing algorithm is that,it is the nodes that decide whether or not to receive and forward the, packets according to the node residual energy,and it is the nodes that maintain their respective neighbor routing information tables and obtain the parameter which indicates the degree of importance of query results packets, and it is the nodes that decide to transmit packets to how many or which of its neighbor nodes. Simulation experiments illustrate that the proposed algorithm displays satisfactory performance in node energy efficiency and network load balance keeping
