一种基于TinyOS的容延迟移动传感器网络协议栈

容延迟移动传感器网络（Delay Tolerant – Mobile Sensor Network, DT-MSN）是指部署在多个移动物体上的传感器节点所组成的稀疏网络。在DT-MSN中，不存在稳定的端到端的多跳路径，基于多跳路径的传统数据传输模式不再适用，这使得DT-MSN采用了一种全新的数据传输模式。由于这一独特的数据传输模式，传统网络协议栈无法用于DT-MSN，针对这种情况，本文提出了一种基于TinyOS的DT-MSN协议栈。该协议栈不仅描述了一种通用的DT-MSN网络架构，而且采用了分层结构和模块化的设计，使得DT-MSN研究人员不仅可以将注意力集中到某一具体的功能模块，还可以根据需要重用现有的功能模块。基于该协议栈架构我们对其进行了实现，并引入了具体的数据传输机制。

A Protocol Stack for DT-MSN on TinyOS

Delay Tolerant-Mobile Sensor Network (DT-MSN) is a sparse network which is composed of motes attached on the mobile objects. In DT-MSN, there does not exist a complete end-to-end path from source to destination, which means the conventional data transmission pattern based on multi-hop path is no more appropriate. As a result, DT-MSN has to employs a new data transmission pattern. This unique pattern results in the failure of conventional protocol stack in DT-MSN. According to this situation, this paper introduces a protocol stack for DT-MSN on TinyOS, which aims at providing an in-depth view of the protocol design and evaluation. This stack describes a general architecture for DT-MSN, and employs the layering model and modularity to allow the researchers concentrate on special function components and reuse the existing components according to their requirements. Based on the structure of this stack, we exemplify it with several popular protocols, in order to demonstrate the soundness of our design.
