融合广播经常用于支持传感器网络应用中的各种任务。我们调查的问题，在无线传感器网络中的汇聚过程中，由于拥塞和碰撞附近的汇，并提出了一个简单而强大的协调汇聚协议，实现高汇聚可靠性的数据包丢失。我们通过仿真研究了新协议的性能，并在可靠性、延迟、吞吐量和能耗之间进行了权衡。为了将该协议与其他现有的汇聚播协议进行比较，使用了真实的应用场景。仿真结果表明，与现有的汇聚组播协议相比，该协议在可靠性上有了显著的提高。
Convergecast is frequently used for supporting various tasks in sensor network applications. We investigate the problem of packet loss in the convergecast process in wireless sensor networks due to congestion and collisions near the sink, and propose a simple yet powerful coordinated convergecast protocol for achieving high convergecast reliability. We study the performance of the new protocol via simulation and show the tradeoffs among reliability, latency, throughput and energy consumption. To compare this protocol with other existing convergecast protocols, a real application scenario is used. Simulation shows that this protocol can achieve dramatic improvement in reliability comparing to existing convergecast protocols.
