在这个物联网（IoT）时代，各种电池供电的设备通过无线多跳通信相互通信或与一些远程网关通信。尽管Wi-Fi因其高数据速率、高可靠性和原生IP兼容性而被证明对广泛的物联网应用有很大的好处，但它本质上是耗能的，并可能面临一个困境：更频繁（更少）使用Wi-Fi会导致更短（更长）的延迟，但更高（更低）的能耗。这种困境成为Wi-Fi在长期但延迟受限的物联网应用中使用的主要障碍。为了解决这个问题，我们提出了一种双向交叉接口调度（BCS）方案，该方案利用广泛使用的低功耗ZigBee与高数据速率和可靠的Wi-Fi协作，以实现可持续和可靠的端到端（E2 E）数据传输物联网。目标是最大化网络寿命，同时满足一定的E2 E延迟限制。已经进行了大量的模拟和试验台实验。结果表明，BCS的网络寿命是33.4%和346.9%，分别比那些国家的最先进的计划和IEEE 802.11的标准节能计划与默认设置，。
In this era of Internet of Things (IoT), a variety of battery-powered devices communicate with each other or some remote gateways via wireless multihop communications. Although Wi-Fi has been shown to be of great benefit to a wide range of IoT applications due to its high data rate, high reliability, and native IP compatibility, it is inherently energy-hungry and potentially suffers from a dilemma: more (less) frequent use of Wi-Fi results in shorter (longer) delay but higher (lower) energy consumption. This dilemma becomes the major obstacle in the use of Wi-Fi in long-term but delay-bounded IoT applications. To address this, we propose a bidirectional cross-interface scheduling (BCS) scheme, which leverages the widely used low-power ZigBee to collaborate with the high data rate and reliable Wi-Fi for sustainable and reliable end-to-end (E2E) data delivery in IoT. The objective is to maximize network lifetime while satisfying certain required E2E delay bound. Extensive simulations and testbed experiments have been conducted. The results show that the network lifetime of BCS is 33.4% and 346.9% longer than those of a state-of-the-art scheme and the IEEE 802.11's standard power-saving scheme with the default settings, respectively.
