Abstract

本发明属于无线网络领域,提出一种用于仿真的移动模型,可用于移动自组网络的相关研究中。

Description

一种用于仿真的移动模型
技术领域
本发明涉及一种用于仿真的移动模型,属于无线网路领域。
 背景技术
移动自组网是一种无需架设网络基础设施的无线通信模式,由于具有展开速度快,抗毁性强的特点,移动自组网在数字化作战***,抗灾救险等领域有着重要作用。
移动模型用来模拟网络中各节点的移动模式,包括其位置、速度、加速度的变化,以便在现实场景不可知或不可模拟的情况下,对基于移动自组网络的***或协议、算法性能进行设计或分析评价。
在目前的移动自组网络协议的模拟研究中多采用随机路点移动模型,在模拟开始时,节点被随机放置的模拟区域中,每个节点选择区域中的一个点作为目标点,然后以随机的速度向目标运动,到达目标之后停顿随机长的一段时间。所有随机的选择都均匀地分布在一个预先给定的范围内,但是由于节点选择需要穿过模拟球中心的目的地或者位于区域中心的目的地的概率会比较高,因此移动节点的移动会出现聚合-分散-聚合的密度波现象。
发明内容
本发明就是针对上述背景技术中的不足之处,提出的一种用于仿真的移动模型。
本发明的目的是通过如下技术措施实现的。
一种用于仿真的移动模型,其节点移动规则遵循如下步骤:
(1)    将仿真区域均匀地划分为若干个区域;
(2)    开始时节点以等同的概率选择上述区域中的一个区域,在该区域内随机选择一个目的地;
(3)    节点在一定的速度范围内以等同的概率选取一个速度值匀速移动,到达目的地后,停留一定时间;之后,重复步骤(2)和(3)直至仿真结束。
 
有益效果
降低了节点在仿真区域中心出现的概率,一定程度上能削弱密度波现象。
具体实施方式
下面结合实施例详细说明本发明的技术方案,但保护范围并不受此限制。
实施例  一种用于仿真的移动模型
仿真区域为4×4的矩形区域,共一个节点,仿真次数为1000个移动周期。
(1)    将仿真区域均匀地划分为32个区域;
(2)    仿真开始时节点以1/32的概率选择32个区域中的一个区域,在该区域内随机选择一个目的地,使其横、纵坐标在该区域内满足均匀分布;
节点的速度满足[0, 2.1]上的均匀分布,到达目的地后,停留时间为零;之后,重复步骤(2)和(3)直至仿真结束。

Claims (1)

1.一种用于仿真的移动模型,其特征在于其移动规则遵循如下步骤:
将仿真区域均匀地划分为若干个区域;
开始时节点以等同的概率选择上述区域中的一个区域,在该区域内随机选择一个目的地;
节点在一定的速度范围内以等同的概率选取一个速度值匀速移动,到达目的地后,停留一定时间;之后,重复步骤(2)和(3)直至仿真结束。
