存在传感器网络的几种应用，其中数据传输的可靠性可能是关键的。虽然传感器网络中固有的冗余可能会增加可靠性的程度，但它绝不能提供任何有保证的可靠性语义。在本文中，我们考虑的问题，可靠的汇到传感器的数据传输。我们首先确定几个基本的挑战，需要解决的，是独特的无线传感器网络环境。然后，我们提出了一个可扩展的框架，用于可靠的下游数据传输，专门设计用于解决和利用无线传感器网络的特性，同时以有效的方式实现可靠性。通过基于ns2的模拟，我们评估所提出的框架。
There exist several applications of sensor networks wherere liability of data delivery can be critical. While the redundancy inherent in a sensor network might increase the degree of reliability, it by no means can provide any guaranteed reliability semantics. In this paper, we consider the problem of reliable sink-to-sensors data delivery. We first identify several fundamental challenges that need to be addressed, and are unique to a wireless sensor network environment. We then propose a scalable framework for reliable downstream data delivery that is specifically designed to both address and leverage the characteristics of a wireless sensor network, while achieving the reliability in an efficient manner. Through ns2 based simulations, we evaluate the proposed framework.
