中文摘要: 利用移动Sink进行数据收集是无线传感器网络数据收集的一个趋势。本文提出一种能量有效、延迟敏感的移动数据收集协议(Energy-efficient and Delay-Sensitive Data Gathering Protocol for Wireless Sensor Networks,简称EEDS)。EEDS中，移动Sink在网络中穿行，从代理节点收集传感器节点监测到的数据。为了减少数据收集的延迟，采用类TSP(Traveling Salesman Problem)的解决方法，确保移动Sink在各个代理节点中收集数据时，始终选择一条最短路径在网络中行走。模拟仿真表明，提出的数据收集协议在延长网络生命周期以及减少数据收集延迟方面都有显著的优势。
Abstract:Using mobile sink to gather data is one of the comprehensive trends in wireless sensor networks. This paper proposes an energy-efficient and delay-sensitive data gathering protocol (EEDS)for wireless sensor networks. In EEDS, The mobile sink traverses in the entire network to upload the sensed data from agent nodes. In order to reduce the length of path which mobile sink traverses the network, the solution of TSP-like is proposed, which ensures mobile sink always choose the shortest path to walk through the network. Simulation results have demonstrated that the proposed data collection strategy has a significant advantage in extending the network life time and reducing data transmission delays.
