提出了一种基于sink简单固定轨迹的动态数据传输算法,算法由数据传输策略和队列管理机制组成,适用于异构延迟容忍移动无线传感器网络.在每一次运动开始,首先判断节点是否可以直接传输消息给汇聚点,然后根据节点能量消耗和传输延迟计算出不同时刻各节点的传输概率,节点根据传输概率进行消息传输或转发.队列管理则根据不同类型消息的生存时间和传输次数来决定对消息的转发和丢弃(被动或主动).实验结果验证了算法的有效性.
A dynamic data transmission algorithm based on sink simple fixed trajectory is proposed, which consists of data transmission strategy and queue management mechanism, and is suitable for heterogeneous delay tolerant mobile wireless sensor networks. At the beginning of each movement, it is first determined whether the node can transmit directly Message to the convergence point, and then calculate the transmission probability of each node at different times according to the node energy consumption and transmission delay, and the node transmits or forwards the message according to the transmission probability.Queue management determines the message according to the survival time and transmission times of different types of messages (Passive or active). The experimental results verify the effectiveness of the algorithm.
