摘要
为了更加深入的研究容迟网络(delay tolerant networks,DTN)路由技术中决定性能表现的主要因素,以3种具有代表性的主流DTN路由为例,设计了一个典型的地区探测场景,利用ONE模拟器进行了仿真实验。实验结果表明,在相同的应用场景下,采用不同策略的DTN路由表现出很大的性能差异。实验数据的对比分析证明,路由算法的性能主要受网络中报文拷贝数量及其转发策略的限制,同时跟网络硬件性能也有很大关系。
For more in-depth research of the main factors deciding the function performance in DTN routing technology, three representative major DTN routing is taken for examples, the simulation experiment is done by design a typical regional detection scene using ONE simulator. The experiment proves that, in the same scene, the DTN routing using different strategies shows much difference in performance. Comparative analysis of experimental data shows that the performance of the routing algorithm is mainly restricted by the network message quantity and the transition strategy, and it has a great relationship with the network hardware performance.
