摘　　要：在需要频繁传输音频的大规模蓝牙网络中,传统的DSDV路由算法会引入极高的时延和功耗。为了实现低功耗低时延的蓝牙网络音频传输,将BLE Audio的同步传输链路引入DSDV路由算法中,并结合根据节点状态自适应改变广播周期的机制,提出了一种面向BLE Audio的改进DSDV路由算法。并且在BLE Audio硬件平台开发和实现了提出的路由算法。实际测试结果表明,该算法不仅能够降低节点功耗,同时能够极大降低音频数据包的端到端时延。In the large-scale Bluetooth network which requires frequent audio transmissions,the traditional DSDV routing algorithm causes extremely high latency and power consumption.In order to achieve low-power and low-latency audio transmission in Bluetooth networks,the isochronous transmission link of BLE Audio is introduced into the DSDV routing algorithm,and an improved DSDV routing algorithm for BLE Audio is proposed by combining the mechanism of adaptively changing the broadcast period based on the node state.Furthermore,the proposed routing algorithm is developed and implemented on the BLE Audio hardware platform.The test results demonstrate that the proposed algorithm can not only reduce node power consumption,but also greatly reduce the end-to-end latency of audio data packets.
