摘要 提出一种多媒体传感器网络中的多路径传输方法。综合考虑传输时间、链路剩余能量及传输速率等因素,通过元数据分组的探寻,建立三类路径,并利用自适应采样时间间隔调整,降低了网络拥塞的可能性。实验表明,本方法在分组丢失率、传输实时性、拥塞控制等方面均表现出良好性能。 A multi-path transmission method for multimedia sensor networks was proposed.By considering the transmission time,residual energy as well as transmission rate of the wireless links,three classes of paths are established with the help of metadata packets.Network congestion rate is reduced as well by adjusting time intervals of sampling.Experiments results show that this method is well performed on packet loss,real-time transmission as well as congestion control.
