在人体传感器网络中，数据冗余和传输延迟是影响网络性能的两个主要问题。在之前的方案中，使用多传感器融合来降低传感器网络的能量消耗，但会造成较大的延迟。为了减少冗余数据量和传输延迟，提出了一种基于分组聚合路由（AFNDCAR）的bsn转发节点和占空比调整方案。AFNDCAR方案的主要贡献如下：(a)节点根据较高的能耗、较长的分组队列长度和分组聚合等待时间来选择转发节点，以减少传输延迟。(b)在密集网络中，调整转发节点数和生成数据包的概率，使传输延迟最小，数据包传输成功率最大。(c)在稀疏网络中，可以利用节点的剩余能量来调整节点的占空比。理论分析表明，该算法显著提高了冗余数据量、节点的传输延迟和能量效率。
In the body sensor networks (BSNs), the data redundancy and transmission delay are two problems for improving network performance. In the previous scheme, multi-sensor fusion is used to reduce the energy consumption of the sensor network, but it causes larger delay. To reduce the amount of redundant data and transmission delay, an adjusting forwarder nodes and duty cycle using packet aggregation routing (AFNDCAR) scheme is proposed for BSNs. The main contributions of the AFNDCAR scheme are as follows: (a) nodes select forwarder nodes based on the higher energy consumption, longer queue length of packets and waiting time of packets aggregation to reduce the transmission delay. (b) In the dense network, the number of forwarder nodes and the probability for generating data packets are adjusted to minimize the transmission delay and maximum the packet transmission success ratio. (c) In the sparse network, the duty cycle of nodes can be adjusted using the energy left of nodes. The theoretical analysis show that the amount of redundancy data, the transmission delay and energy efficiency of nodes improved significantly.
