基于轻型机步野战场景的DTN通信策略设计与性能分析

Strategy Design and Performance Analysis of Delay Tolerance Network Based on Tactical Battlefield

通过对基于轻型机步野战场景的DTN通信策略的研究,提出了一种新的DTN通信策略,根据排队论G/G/1模型和切比雪夫不等式对提出的DTN通信策略进行了建模和关键参数的理论值推算,利用ONES架构对轻机步DTN场景进行了仿真实验,将得到的实验数据与预期值进行对比和分析,验证了通信策略的正确性,确定了影响系统传输效率的关键因素,并在相同仿真场景下与感染路由策略做了性能比较。

Based on the research of the DTN communication strategy in tactical battlefield,a novel DTN c ommunication strategy was proposed.It was modeled and calculated key parameters by using G/G/1 model and Chebyshev inequality.Also the whole DTN process under ONEs simulation tools was simulated.The key factors that affect the system transmission efficiency by comparing the experimental data with the expected value was comfined.The perfomance of the novel strategy compared with epidemic router strategy in the same simulation scenarios.
