摘　　要：为制衡无线多跳网络中的服务质量和节点能耗,提出成本函数和分组聚合算法的优化方案。分析聚合数据包分组的数量对服务质量和节点能耗的影响,利用成本函数将两者融合于同一个函数中。由于成本函数的最优值点也是两者平衡的最优值点,因此得到聚合数据包分组数量的最优值。仿真结果表明,该方案可以较好地在服务质量和节点能耗之间取得平衡。For the problem of the balance between Quality of Service（QoS） and energy consumption of the nodes in aggregation algorithm which is conducted in the wireless multi-hop network,a cost function and performance optimization scheme of packet aggregation algorithm is proposed.The impact of the number of aggregation packets on quality of service and nodes energy consumption is analyzed,and the cost function is utilized to merge the two values into a function.The optimal value of the cost function is also the optimal value of the balance between QoS and energy consumption of the nodes,and it can get the optimal value of the number of aggregation packets.Proposed scheme is realized by simulate to verify the effectiveness of the proposed scheme.Simulation results show that the proposed scheme can balance the QoS and energy consumption.
