SGER: A Novel Information Model for Efficient Routing Protocols in Delay Tolerant Networks with General Mobility

具有一般移动性的容延迟网络中高效路由协议的新信息模型本项目支持具有一般移动性的容延迟网络中高效路由协议的新信息模型的研究。容忍延迟网络（Delay tolerance Network， DTN）是一种不保证源端和目的端在任何时候都有路径的无线移动网络。它在传感器网络、卫星网络、水声网络和偏远地区的互联网连接中有着广泛的应用。在这个项目中，节点的迁移是无法预测的。由于网络连接的不确定性和时变性质，具有一般移动性的ddn中的路由提出了独特的挑战。为了方便布线，研究了一种新的信息模型，该模型采用最小二乘法及其变体。这些技术涉及每个节点应该收集和处理的信息，以便即使目的地的位置未知且不可预测，也能尽快将消息传递到目的地。

A Novel Information Model For Efficient Routing Protocols in Delay Tolerant Networks with General MobilityThis project supports the research on a novel information model for efficient routing protocols in delay tolerant networks with general mobility. Delay Tolerant Network (DTN) is a type of wireless mobile network that does not guarantee the existence of a path between a source and a destination at any time. It has broad applications in sensor-based, satellite, underwater acoustic networks, and Internet connectivity in remote places. In this project, nodes mobility cannot be predicted. Routing in DTNs with general mobility poses unique challenges due to the uncertainty and the time-varying nature of network connectivity. To facilitate the routing, a novel information model using the least square methods and their variations are explored. The techniques involve the information that each node should gather and process so that the message can be delivered to the destination as soon as possible even though the location of the destination is unknown and unpredictable.
