中文摘要： 无线传感器/执行器网络(WSAN)中移动执行器节点与休眠传感器节点的共存，使得数据传输过程同时具有时变和时滞的特性。因此，独立的移动性管理和休眠唤醒机制难以满足用户对传输的服务质量(QoS)和能耗效率的需求。针对上述问题，本项目将对移动性管理和休眠唤醒机制的联合调度与优化展开研究。研究首先利用执行器节点的移动路径与传输路径的时空相关性，通过执行器节点的"足迹"来刻画传输路径的动态特性，进而将足迹跟踪与位置服务算法结合，设计能够容忍休眠时延的移动性管理机制；其次，以移动性管理机制建立的传输路径为基础，设计分段的休眠唤醒机制，通过建立连续的唤醒时隙序列减少传输过程的等待时延；最后综合分析移动性管理和休眠唤醒机制对网络性能的影响，求解在QoS约束条件下的能耗优化问题。本项目的研究将促进移动执行器和休眠机制在WSAN中的应用，并为提高WSAN的服务质量和能耗效率提供理论和技术支撑。

英文摘要： In wireless sensor and actor networks (WSAN), the coexistence of the mobile actor nodes and sleeping sensor nodes makes the data transmission process has the characteristics of time-varying and delay simultaneously. Therefore, the independent design of mobility management and duty cycle scheduling is difficult to meet the requirements of quality of service (QoS) and energy efficiency. In order to solve these problems, this project will study the joint scheduling and optimization of mobility management and duty cycle in WSAN. At first, we will exploit the spatio-temporal relations between the actor movement path and data transmission path, then use the "footprints" of actor nodes to characterize the dynamic characteristics of the transmission path. Then we will combine the footprint tracking algorithm with location services to design the mobility management schemes that can tolerate the sleep latency. Based on the transmission path established by the mobility management, we will study asynchronous duty cycle scheduling scheme which builds a continuous wake-up slots sequence to reduce the waiting delay during data transmission. Finally, we will evaluate the impact of the proposed mobility management and duty cycle scheduling schemes on network performance, and try to solve the optimization problem of minimize the
