摘　　要：为了延长无线传感器网络的生命周期,并从节点能耗负载均衡的角度进行数据传输,提出了一种高效的基于负载均衡树的数据聚合方案(LB-TBDAS)。该方案将传感区域划分为网格中的多个单元,选出剩余能量最大的传感器节点作为每个单元中的头部单元;利用最小生成树算法建立树状路径。在数据传输过程中,头部单元负责采集每个单元内的传感数据,采集到的数据沿树状路径传输到基站。仿真结果表明,提出的LB-TBDAS方案的总能耗明显低于GB-PEDAP和PED-AP。与GB-PEDAP和PEDAP相比,LB-TBDAS方案延长了一倍以上无线传感器网络的生命周期,可以避免传感器节点在多跳数据传输过程中产生过多的能量消耗。In order to extend the lifecycle of wireless sensor networks and achieve data transmission from the perspective of node energy consumption and load balancing,an efficient Load Balancing Tree Based Data Aggregation Scheme(LB-TBDAS)is proposed.This scheme divides the sensing area into multiple units in the grid,and selects the sensor node with the highest remaining energy as the head unit in each unit;Establish a tree like path using the minimum spanning tree algorithm.During the data transmission process,the head unit is responsible for collecting sensing data within each unit,and the collected data is transmitted along a tree like path to the base station.The simulation results show that the total energy consumption of the proposed LB-TBDAS scheme is significantly lower than that of GB-PEDAP and PEDAP.Compared with GB-PEDAP and PEDAP,the LB-TBDAS solution extends the lifecycle of wireless sensor networks by more than twice,which can avoid excessive energy consumption of sensor nodes during multi hop data transmission.
