无线通信系统的快速发展推动了支持大规模无线系统仿真的技术的发展。然而，人们广泛认识到，无线通信不具有保守同步协议所需的实质性“先行”。本文的重点是识别和利用前瞻性等模型。我们发现前瞻性的三种方式，利用低功耗网络的特点，收发器的逻辑，以及协议栈通常构造的方式。我们展示了这些观察如何允许各种保守的同步协议，以利用前瞻，描述了我们使用的同步方法，并实证研究这种方法提供的性能上的一个大规模模拟的传感器网络打算为国土防御方案
Rapid growth in wireless communication systems motivates the development of technology supporting the simulation of large-scale wireless systems. However, it is widely recognized that wireless communications do not have substantial "lookahead" needed by conservative synchronization protocols. This paper focuses on identifying and exploiting lookahead for such models. We find lookahead in three ways, exploiting characteristics of low power networks, the transceiver logic, and the way in which protocol stacks are typically constructed. We show how these observations allow a variety of conservative synchronization protocols to take advantage of lookahead, describe a synchronization method we use, and empirically examine the performance this method offers on a large-scale simulation of a sensor network intended for homeland defense scenarios
