Development of communication scheduling schemes for mobile sensor networks consisting of nodes without autonomous mobility

针对利用丢入管道中的多个无线传感器节点检测污水管道等水管的形状或故障点的问题，设计了管道内流动无线传感器网络（PFWSN）的体系结构、调度方案和数据采集方案。通过仿真验证了基于改进的HEED算法和基于随机丢弃的传输缓冲管理算法的主动节点选择和唤醒/睡眠调度对网络是有效的。

Aiming for detecting the shape or failure points of water pipes such as sewerage pipes using multiple wireless sensor nodes thrown into the pipes, we designed architecture of In-Pipeline Flowing Wireless Sensor Networks(PFWSN) and scheduling schemes and data collecting schemes for the networks. We confirmed that active node selection and wake-up/sleeping schedule of based on our improved HEED algorithm and Random Drop-based transmission buffer management algorithm is effective for the network through simulation.
