新兴的无线传感器/执行器网络WSAN技术有可能实现半自动气流控制，以改善飞机的空气动力学性能。本文提出了一种由多个由执行器终止的线性传感器簇组成的无线存储区域网络，用于主动气流控制，目标是最小化汇聚广播延迟。这里，收敛延时被定义为从采样周期开始到该采样周期的所有传感器数据被执行器接收所需的时间。通过最小化并发数据传输的间隔距离，使同一时隙内发送数据的节点数量最大化来实现这一目标。该问题转化为具有适当干扰分离选择的调度问题。然而，大多数已有的线性网络调度工作都使用最小两跳间隔来避免冲突。本文研究了跳频间隔、信噪比和选择干扰间隔的时延之间的关系。提出了一种新的干扰感知混合线路调度HLS算法，并对其能量消耗进行了分析。分析和仿真结果表明，与其他调度策略相比，在节点密度较高的情况下，精心选择跳数间隔的HLS算法能在一定程度上降低时延和能耗，最高可达15%。版权所有©2012 John Wiley&Sons，Ltd.
Emerging wireless sensor/actuator network WSAN technology has the potential to enable semi-autonomous airflow control to improve the aerodynamic performance of aircraft. In this paper, a WSAN comprising of multiple linear sensor clusters terminated by actuators is proposed for active airflow control with the objective of minimizing convergecast latency. Here, the convergecast delay is defined as the time required from the beginning of a sampling period to all all sensor's data of this sampling period is received by the actuator. The objective is achieved by minimizing the separation distance of concurrent data transmission so that the number of nodes sending data in the same time slot is maximized. The problem turns into a scheduling problem with a proper selection of interference separation. However, most existing work on the scheduling in linear networks use the minimum separation of two hops to avoid collisions. This paper examines the relationship between the hop separation, signal-to-noise ratio, and the latency to make a selection of interference separation. A new interference aware hybrid line scheduling HLS algorithm is proposed and its energy consumption is analyzed. Compared with other line scheduling policies, the analysis and simulation results show that, at moderately high node densities, the proposed HLS with carefully selected hop separation is able to reduce both the delay by up to 15% and the energy consumption somehow.
