This paper investigates scheme of Tethered Balloon network architecture based public safety network and emergency communications. Recently, Tethered Balloon technology represents the most powerful and promising technology to improve the public safety and saving people lives. The capability of network architecture enables Tethered Balloon to accomplish unique and specific missions for temporary events such as natural hazardous and terrorist acts. Natural hazardous and terrorist acts have significant potential to disrupt the entire terrestrial wireless communication infrastructure. In order to mitigate the effects of catastrophic, we propose Tethered Balloon as the key technology for delivering broadband services where communication infrastructures are partially or totally destroyed. This work is done by using OPNET Modeler 14.5 for network implementation. The result is shown the significant performance of using proposed technology to provide high priority for disaster area and deliver broadband communication services. It proves that rescue teams have significantly performed their duty effectively and efficiently.

“…This study was undertaken to understand the ways of fulfilling the requirements for SAGIN's delay, reliability, bandwidth, and QoS and explore the approaches for solving these problems. The issues of creating and using SAGIN are considered in articles (Bithas et al, 2019; Grekhov et al, 2020a, 2020b; Grekhov, Kondratiuk, et al, 2019; Liu et al, 2018; Marchese et al, 2019; Wang et al, 2016; Xiong et al, 2016; Yan et al, 2019; Yang et al, 2019; Yao et al, 2018; Zhang et al, 2017; Zhu et al, 2017), and reviews (Grekhov, 2019; Yan et al, 2019) are devoted to modeling RPAS/UAV communication channels.…”

“…Overloading and paralysis of terrestrial networks during disasters and catastrophes forces to solve the problems of fast emergency communications network deployment with a high data rate and wide coverage. Hybrid satellite‐aerial‐terrestrial (HSAT) networks are reviewed in (Wang et al, 2016) in terms of emergency scenarios. HSAT aerial platforms and networks are discussed, as well as key technologies for delivering effective services during an emergency.…”

Remotely piloted air systems (RPASs) are increasingly used for data transmission in the space‐air‐ground integrated networks (SAGINs). That is why it is important to know the possibilities and ways of integrating existing space, air and terrestrial networks for effective interaction with RPASs. This paper studies the issues of ensuring the required quality of service during heavy traffic in SAGIN and the choice of the necessary data transmission modes for this. Models of communication channels were created, including line‐of‐sight transmission (Model 1), public terrestrial network (PTN) (Model 2), low‐orbit satellite transmission (Model 3) and PTN plus satellite transmission (Model 4). The relationships between models' performance and traffic parameters, channel bandwidths, bit errors, lost packets and models' topology were investigated using NetCracker Professional 4.1 software. The dependencies of the average utilization on the transaction size and the time between transactions with different statistical distribution laws were analyzed. The effect of different bandwidths was investigated. The influence of the bit error rate and the probability of packet fail chance on the channel performance was studied. The traffic characteristics in all models were compared.

Establishing a reliable communication infrastructure at an emergency site is a crucial task for mission-critical and real-time public safety communications (PSC). To this end, use of unmanned aerial vehicles (UAVs) has recently received extensive interest for PSC to establish reliable connectivity in a heterogeneous network (HetNet) environment. These UAVs can be deployed as unmanned aerial base stations (UABSs) as part of the HetNet infrastructure. In this article, we explore the role of agile UABSs in LTE-Advanced HetNets by applying 3GPP Release-11 further-enhanced inter-cell interference coordination (FeICIC) and cell range expansion (CRE) techniques. Through simulations, we compare the system-wide 5th percentile spectral efficiency (SE) when UABSs are deployed in a hexagonal grid and when their locations are optimized using a genetic algorithm, while also jointly optimizing the CRE and the FeICIC parameters. Our simulation results show that at optimized UABS locations, the 3GPP Release-11 FeICIC with reduced power subframes can provide considerably better 5th percentile SE than the 3GPP Release-10 with almost blank subframes.
