针对现有的协议都不能在获得良好的节能效果和低延迟的同时,使每一个节点进行充分的数据融合的问题,提出一种基于跨层调度的数据融合策略,根据建立的路由树,制订无碰撞的数据发送调度方案并为每一个传感器节点设置合理的等待时间。仿真结果表明此策略节能效果明显、延迟小并且吞吐量大。
The existing protocols can' t set appropriate time for every node to fuse data effectively, while providing great energy conservation and low latency. This paper proposed a strategy of data fusion based on cross-layer scheduling, which made a collision-free data transmission schedule and set appropriate waiting time for each sensor node according to the routing-tree. Simulation results show that the strategy provides significant energy savings, latency reduction and throughput increase.
