无线传感器网络(WSNs)最近获得了大量的关注作为一个研究课题,具有广泛的应用正在探索。批量数据分发是传感器网络应用的基本构建块。设计有效的批量数据传播协议的问题已经在最近的一些研究中得到了解决。然而,准确地分析这些协议的性能的问题,还没有得到充分的文献中。在这项工作中,我们展示了一种方法,准确地分析在无线传感器网络中的批量数据传播协议的性能。我们的模型可以应用到实际的网络拓扑结构,通过使用最短的传播路径,我们的模型是准确的,考虑到拓扑信息,竞争的影响,和流水线的影响。我们通过试验台和详细的模拟验证分析结果。结果表明,分析结果与试验台结果和仿真结果吻合较好。此外,我们证明,分析结果可以用来帮助协议设计的性能优化,例如,页面大小调整,缩短完成时间。
Wireless sensor networks (WSNs) have recently gained a great deal of attention as a topic of research, with a wide range of applications being explored. Bulk data dissemination is a basic building block for sensor network applications. The problem of designing efficient bulk data dissemination protocols has been addressed in a number of recent studies. The problem of accurately analyzing the performance of these protocols, however, has not been addressed sufficiently in the literature. In this work, we show a way of accurately analyzing the performance of bulk data dissemination protocols in WSNs. Our model can be applied to practical network topologies by use of the shortest propagation path. Our model is accurate by considering topological information, impact of contention, and impact of pipelining. We validate the analytical results through testbeds and detailed simulations. Results show that the analytical results fit well with the testbed results and simulation results. Further, we demonstrate that the analytical results can be used to aid protocol design for performance optimizations, e.g., page size tuning for shortening the completion time.
