摘　　要：为了减少多跳无线传感器网络发生稀疏事件时数据传输的开销和延迟,提出一种新的基于压缩传感(CS)的数据传输与重构协议。提出的协议不是避免碰撞,而是利用干扰构建了一种泛洪过程的路由选择,通过测量数据的有效叠加,实现在任何节点都可以同时接收到数据,且每个节点都能向Sink恢复并且转发新数据。仿真结果表明,与传统方法相比,提出的协议延迟减少了25%,且以更低的开销实现了近乎于零的重建误差。In order to reduce the cost and delay of the data transmission when the multi-hop wireless sensor network appears in sparse event,a new data transmission and reconstruction protocol based on compressed sensing（CS）is proposed. The proposed protocol utilizes the interference to construct a route selection of flooding process,but is not used to avoid the collision.The fact that any nodes can receive the data simultaneously by valid superposition of the measuring data is realized. Each node can recover and transmit the new data to Sink. The simulation results show that,in comparison with the traditional method,the delay of the proposed protocol is reduced by 25%,and the reconstruction error approaching to zero is realized with lower cost.
