Research on the Analytical Method for Survivability of Airborne Ad-Hoc Networks Based on Information Timeliness
摘要
Abstract
The airborne Ad-Hoc network needs to interact with the target in a timely manner based on the environmental information sensed by the aircraft for real-time decision-making.However,most of the existing research on network survivability focuses on the effective transmission of information within the network,while ignoring that the airborne Ad-Hoc network is an end-to-end complex network integrating information sensing,transmission,and processing decision-making.To address this issue,this paper proposed an analytical framework for the survivability of airborne Ad-Hoc networks based on the information timeliness,where the age of information(AoI)represents the survival time of the latest successfully received sensing data used for decision-making at the receiver,characterizing the information timeliness.For the airborne Ad-Hoc network scenario,via extracting the spatial distribution characteristics of aircraft,the time dynamics of information sensing,and the signal propagation attenuation characteristics,this paper adopted a spherical Poisson point process and Bernoulli arrival process to establish the spatio-temporal network model of the airborne ad-hoc network.Considering two extreme retransmission strategies,the AoI metric is decomposed into end-to-end transmission delay and the interval between successive successful transmissions.By using stochastic geometry and queuing theory,an analytical expression is derived for the average peak AoI.Numerical analysis investigated the impact of key system parameters on the AoI,providing the critical system parameter values such as information sensing frequency,information transmission duration,and network node density that keep the AoI finite.This offers theoretical guidance for the practical design of airborne Ad-Hoc networks.关键词
