Abstract

Connectivity of Mobile Ad-hoc Networks (MANET) is highly dependent on the mobility model it follows. From previous studies, it has been found that Random Waypoint Mobility Model (RWP) is widely used to simulate performance of the MANETs. This mobility model resembles the mobility of people using mobile phones in a given area. Connectivity is an important issue in a MANET following RWP model and hence researchers are trying out different ways to enhance connectivity. So, this model is considered and the variation of connectivity for different varying parameters is studied. The RWP model is simulated in MATLAB, followed by the study of the node connectivity by changing different parameters like number of user nodes, simulation time and simulation area. Further, it is shown that connectivity is enhanced in each case after introducing agent nodes. This study gives an estimate of number of nodes required for achieving desired connectivity of the network.
移动自组织网络随机航路点移动模型仿真研究
移动自组织网络(MANET)的连通性高度依赖于它所遵循的移动性模型。从以往的研究中发现,随机路点移动模型(RWP)被广泛用于模拟自适应机动网络的性能。这种移动性模型类似于人们在特定地区使用手机的移动性。在遵循RWP模型的MANET中,连通性是一个重要的问题,因此研究人员正在尝试不同的方法来增强连通性。因此,考虑了该模型,研究了不同变化参数下的连通性变化。首先在MATLAB中对RWP模型进行仿真,然后通过改变用户节点数、仿真时间、仿真面积等参数对节点连通性进行研究。此外,在引入代理节点后,在每种情况下连接性都得到了增强。本研究给出了实现期望的网络连通性所需的节点数量的估计。
