航空自组网节点密度与组网概率分析

Analysis of the Node Density and Probability of Forming A Network in Aeronautical Ad hoc Networks

随着Adhoc的发展,人们开始研究它在航空通信领域的应用。应用于航空通信中的Adhoc有很多特点,如节点运动速度快,节点密度小,通信距离远,频段为超短波波段等。而节点的密度是关系到能否构成航空自组网的首要问题。提出了一种航空自组网的模型,并研究了在该网中节点密度与能否组成Adhoc网络的关系。利用贝努利试验的思想,推导出了在不同节点密度下一定区域内节点个数与其对应概率的关系式和节点密度与组网概率之间的关系式,并通过随机试验进行了仿真验证。为研究航空自组网提供重要的参考依据。

With the progress of Ad hoc networks, people begin to study its application in aeronautical communications. Some achievements have been made in certain countries. Other than common usage, in aeronautical communication, the nodes have a higher speed and a lower node density and the frequency is the U/VHF. Among these characters, the low node density is the main problem because as it determines whether or not an aeronautical Ad hoc network can be formed. The paper presents a model of the aeronautical Ad hoc n...
