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.

具有一般移动性的延迟容忍网络中有效路由协议的一种新的信息模型本项目支持对具有一般移动性的延迟容忍网络中的有效路由协议的一种新的信息模型的研究。延迟容忍网络(DTN)是一种无线移动网络，它在任何时候都不保证源和目的地之间存在路径。它在传感器、卫星、水声网络和偏远地区的互联网连接方面有着广泛的应用。在这个项目中，节点的移动性是无法预测的。由于网络连通性的不确定性和时变性，具有一般移动性的DTN中路由提出了独特的挑战。为了便于布线，探索了一种使用最小二乘方法及其变体的新的信息模型。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和不可预测，也可以将消息尽快传递到目的地。
