基于DTN的地震救助移动模型及路由策略的研究

Research on earthquake rescue mobility model and routing strategy based on DTN

通过分析地震救援在黄金时间内的特性需求,在随机路径点模型和随机方向模型的基础上提出了基于DTN(delay tolerance network,DTN)的地震救助移动模型。在该模型下分别对灾民自救和救援队救助两个阶段进行研究,并提出了适合于地震救援系统的路由策略,通过机会网络仿真环境ONE进行仿真实验并验证了该移动模型和路由策略的正确性。

Based on random waypoint and random direction model,this paper proposed a novel earthquake relief mobility model through analyzing the demand characteristics of earthquake relief within prime time. Then,through analyzing victims self-rescue and rescue from relief teams these two phases respectively,it proposed the routing strategy for earthquake rescue.This mobility model and routing policy are validated correct by simulation experiments with the opportunistic network environment simulator.
